  • U.S. Embassies Halt Air Quality Monitoring Abroad

    U.S. Embassies Halt Air Quality Monitoring Abroad


    What’s the air quality in New Delhi, Jakarta or Buenos Aires? Until Tuesday, the United States Embassy in those cities could have told you.

    But the Trump administration has effectively shut down a global air quality monitoring program, ending more than a decade of public data-collection and reporting from 80 embassies and consulates worldwide.

    The information has supported research, helped thousands of foreign service officers working abroad to decide if it was safe to let their children play outdoors, and has directly led to air quality improvements in countries like China.

    The State Department said in an email that the program was being suspended “due to budget constraints.”

    Health officials and environmental experts said ending air quality monitoring would hurt Americans overseas, particularly those who work for the U. S. government.

    “Embassies are situated sometimes in very difficult air quality circumstances,” said Gina McCarthy, who led the Environmental Protection Agency in the Obama administration.

    She, along with John Kerry, who was secretary of state at the time, expanded globally what had been a limited but transformational air monitoring effort in China.

    “You can’t send people in risky areas without information,” Ms. McCarthy said. “We generally think of risky areas as war zones or something like that. But it’s equally important to look at whether their health is deteriorating because they are in a place with such poor air quality.”

    In 2008, United States officials in Beijing installed air quality monitors on the roof of the American Embassy and eventually began posting data hourly about levels of one of the most dangerous types of air pollutants, tiny particulate matter known as PM 2.5. The particles can enter the lungs and bloodstream and have been linked to respiratory problems, heart attacks and other serious health effects.

    The information revealed what local residents already knew: that pollution was far worse than the Chinese government would acknowledge.

    “All hell broke loose,” Ms. McCarthy recalled. The Chinese government tried unsuccessfully to pressure the American Embassy to stop making the data public, calling the readings illegal and attacking the quality of the science, she and others said.

    Ultimately, Chinese officials relented. They put in place their own monitoring system, increased the budget for pollution control and eventually began collaborating with the United States on air quality projects.

    In 2015, Ms. McCarthy and Mr. Kerry announced that they would expand air monitoring across American diplomatic missions, arguing that air pollution, like climate change, required global data and solutions.

    A 2022 study published in the Proceedings of the National Academy of Sciences found that when U.S. embassies began tracking local air pollution, host countries took action. The study found that, since 2008, there had been substantial reductions in fine particulate concentration levels in cities with a U.S. monitor, resulting in a decrease in the risk of premature death for more than 300 million people.

    Dan Westervelt, a research professor at Columbia University’s Lamont-Doherty Earth Observatory, said many countries did not have public air quality monitoring and that the data from the embassies provided researchers with reliable information.

    Dr. Westervelt said he had been working on a project through the State Department using air quality data from embassies in five West African countries, but received a stop-work order when President Trump took office in January.

    “In my opinion it puts the health of foreign service officers at risk,” he said. “But they’re also hindering potential research and policy.”

    The data had appeared on AirNow, a website that was managed by both the E.P.A. and the State Department, and also on ZephAir, a mobile application run by the State Department. On Tuesday the website was offline and no data was being shown on the app.

    The State Department said the air monitors at embassies would continue to run for an undetermined length of time but would not be sending live data to the app or other platforms “if/until funding for the underlying network is resolved.”

    Embassies and other posts would be able to retrieve historical data through the end of the month, according to an internal email viewed by The New York Times.

  • Donald Shoup, 86, Dies; Scholar Saw the Social Costs of Free Parking

    Donald Shoup, 86, Dies; Scholar Saw the Social Costs of Free Parking


    Donald Shoup, a professor of urban studies whose provocative and occasionally amusing 734-page treatise on the economics of parking sparked reforms in thousands of cities, helping reduce traffic, create green space and make cities more walkable, died on Feb. 6 at his home in Los Angeles. He was 86.

    The cause was a stroke, his wife, Pat Shoup, said.

    Professor Shoup was an intellectual hero to urbanists. His disciples called themselves the Shoupistas — their Facebook group has more than 8,100 followers — and referred to their bearded guru as Shoup Dogg, after the rapper Snoop Dogg.

    Professor Shoup, who bicycled to his office at the University of California, Los Angeles, in khaki pants and a tweed sport coat, did not rap. But he managed to take a dry subject — parking — and turn it into an entertaining one.

    “Many of us,” he liked to remind conference audiences, “were probably even conceived in a parked car.”

    In his 2005 book, “The High Cost of Free Parking,” a hefty tome that legions of urban studies students have lugged around to the detriment of their spinal cords, Professor Shoup explained the problems that city planners created by providing too much free or underpriced parking after automobile use soared in the early 20th century.

    He liked to quote George Costanza, the bald, neurotic “Seinfeld” character: “My father didn’t pay for parking, my mother, my brother, nobody. It’s like going to a prostitute. Why should I pay when, if I apply myself, maybe I can get it for free?”

    To Professor Shoup, that quote showed the economic calculus that drivers make: Instead of paying for a pricey garage, they are tempted to keep looking and waiting for an elusive (and cheaper) spot to become magically available — wasting energy and creating traffic and air pollution in the process.

    In Professor Shoup’s 2005 book, he explained the problems that city planners created by providing too much free or underpriced parking after automobile use soared in the early 20th century.Credit…Routledge

    “The curb spaces are like fish in the ocean: a parking space belongs to anyone who occupies it, but if you leave it, you lose it,” Professor Shoup wrote. “Where all the curb spaces are occupied, turnover leads to a few vacancies over time, but drivers must cruise to find a space vacated by a departing motorist.”

    As cities grew, free or inexpensive parking was regarded as an inalienable right. City planners mandated that developers provide off-street parking for residential and commercial projects, incentivizing driving over other forms of transportation. It was a waste of valuable land, Professor Shoup noted, that contributed to urban sprawl.

    He drew on the board game Monopoly to illustrate his point.

    “In Monopoly, free parking is only one space out of 40 on the board,” he wrote. “If Monopoly were played under our current zoning laws, however, free parking would be on every space. Parking lots might cover half of Marvin Gardens, and Park Place would have underground parking.”

    The problem would mushroom.

    “Free parking would push buildings farther apart, increase the cost of houses and hotels, and permit fewer of them to be built at all,” Professor Shoup wrote. “Smart players would soon leave Atlantic City behind and move to a larger board that allowed them to build on cheaper land in the suburbs. Connecticut Avenue would not be redeveloped with hotels, the railroads would disappear and every piece on the board would move more slowly.”

    He proposed a three-pronged solution: Ban off-street parking requirements, letting developers (and market forces) dictate how much parking to supply; employ dynamic pricing for on-street parking, raising prices when demand is highest; and spend the resulting increased revenue from meters to spruce up sidewalks, encouraging more walking.

    “The High Cost of Free Parking” was widely praised, especially for turning parking into a riveting read.

    “When I told a group of transportation colleagues about the book, they expressed both disbelief and sympathy — how could there be that much to say about parking, let alone anything interesting?” Susan Handy, a professor of environmental science and policy at the University of California, Davis, wrote in The Journal of Planning Education and Research. “But as Shoup adeptly shows, parking is interesting, and it is hugely important.”

    The book captured the attention of progressive policymakers and grass roots activists, who began pushing for cities big and small to adopt Professor Shoup’s ideas.

    “Don is treated in some places like Einstein, like he has discovered the theory of relativity,” Bonnie Nelson, a founder of Nelson\Nygaard, a transportation consulting firm, told The Los Angeles Times in 2010.

    More than 3,000 cities have adopted some or all of Professor Shoup’s recommendations, according to the Parking Reform Network, a nonprofit that champions the book’s ideas.

    “The size and breadth of this book gives it authority,” Tony Jordan, the group’s founder, said in an interview. “You can literally stand on it when you make an argument.”

    Donald Curran Shoup was born on Aug. 24, 1938, in Long Beach, Calif. His parents were Francis Elliott Shoup Jr., a captain in the U.S. Navy, and Muriel Shoup, who ran the home.

    When Donald was 2, the Shoups moved to Honolulu, where his father was stationed.

    “The only thing I’m famous for is that I was living in Honolulu when Pearl Harbor was attacked,” he recalled in an interview with the American Planning Association. “So I think everything has been very calm ever since. If you start with Pearl Harbor as your first memory, life seems very easy.”

    He studied electrical engineering and economics at Yale and then did his graduate studies there in economics, receiving his doctorate in 1968.

    After teaching at the University of Michigan, he joined U.C.L.A.’s department of urban planning in 1974.

    Back then, parking wasn’t exactly in vogue as a scholarly subject. He covered his office door with cartoons about it.

    “Because most academics cannot imagine anything less interesting to study than parking, I was a bottom feeder with little competition for many years,” Professor Shoup wrote in “The High Cost of Free Parking.” “But there is a lot of food down there, and many other academics have joined in what is now almost a feeding frenzy.”

    He was married for 59 years to Ms. Shoup, who helped edit his writing. She is his only immediate survivor.

    Professor Shoup loved being called Shoup Dogg, she recalled, and even used the nickname as his website address.

    “He would do absolutely anything,” she said, “to get people to pay attention to the important issue of parking.”

  • Delhi-NCR’s Poor Air Quality NOT Linked To Crop Burning In Punjab And Haryana, Claims Study

    Delhi-NCR’s Poor Air Quality NOT Linked To Crop Burning In Punjab And Haryana, Claims Study


    New Delhi: The high PM2.5 levels in Delhi-NCR are largely independent of crop residue burning (CRB) in Punjab and Haryana, and are due to local reasons, claimed a study by researchers from Japan, based on an analysis of observations across a network of 30 sites, on Tuesday. 

    The study, part of the Aakash Project led by a team from the Research Institute for Humanity and Nature (RIHN) in Kyoto, showed that even during the peak rice stubble burning period (October-November) crop fires are not the reason for poor air quality in the national capital and adjacent areas.

    The adverse impacts of air pollution on human health, economic activities, and lifestyle have been a major concern for decades as pollution at an alert level occurs each year during the Oct-Nov months in Delhi-NCR.


    Large contributions from the paddy CRB in Punjab and Haryana states of northwest India have been reported as a major reason for this air pollution seen in the national capital and adjacent areas.

    “Our study underscores the importance of continuous monitoring of air pollution in both source (Punjab), receptor (Delhi-NCR) and intermediate (Haryana) regions for implementation of targeted mitigation strategies to combat the persistency of harmful air pollution,” said lead author Dr. Poonam Mangaraj, from the institute.

    “We have concluded that CRB in Punjab and Haryana cannot be made responsible for determining the air quality in Delhi-NCR, even during the peak rice stubble burning period (Oct-Nov),” said the researchers in the paper published in the journal npj Climate and Atmospheric Science.

    In the study, the team installed 30 units of compact and useful PM2.5 in situ instruments with gas sensors (CUPI-Gs) which have continuously recorded air pollutants in 2022 and 2023.

    They used a combination of (1) measurements from the low-cost CUPI-G network, (2) analyses of air mass trajectories, fire counts, and wind patterns, and (3) chemistry-transport simulations to assess the impact of CRB on PM2.5 in rural, sub-urban and megacity regions.

    The findings highlight that, despite a significant reduction in the satellite fire detection counts (FDCs) over Punjab and Haryana from 2015 to 2023, PM2.5 concentrations in Delhi have remained high.

    The PM2.5 concentrations showed large day-to-day fluctuation from site to site in both 2022 and 2023.

    Both years saw significant fire counts in southwest Punjab with daily-mean PM2.5 exceeding 300 micrograms per cubic metre of air in Delhi, but the meteorological conditions were markedly different for the peak CRB days of November 1-12 of 2022 and 2023.

    November 2022 witnessed a prevalence of northwesterly winds allowing the transport of airmass from Punjab and Haryana to Delhi-NCR on two occasions.

    However, in November 2023, a southwesterly low wind condition and limited air movement caused an accumulation of local pollutants in Delhi-NCR.

    The analyses showed that the buildup and sustenance of PM2.5 in the Delhi-NCR is primarily of local origin and can be inferred from the rise/drop in concert with the implementation/revocation of the Graded Response Action Plan (GRAP) stages as administered by the Commission of air quality management (CAQM).

    “With the measurements at a network of about 30 sites covering Punjab, Haryana, and Delhi NCR, we are able to separate the contributions of paddy straw burning to Delhi’s PM2.5 variations on the basis of characteristic PM2.5 events and at week-monthly averages,” said Prof. Prabir Patra, the leader of Aakash Project and principal scientist at Japan Agency for Marine-Earth Science and Technology (JAMSTEC).

  • The Silent Killer: How Air Pollution Worsening Respiratory Diseases And Cardiovascular Health, Check What Doctor Says

    The Silent Killer: How Air Pollution Worsening Respiratory Diseases And Cardiovascular Health, Check What Doctor Says


    Delhi-NCR is currently struggling with severe pollution, with the AQI in many areas surpassing 349. This situation remains extremely critical, leading to school closures and the implementation of various restrictions. Air pollution has become an overlooked and serious crisis. Due to the increasing pollution, not only are respiratory issues on the rise, but heart-related problems are also becoming more prevalent. 

    Air pollution is often referred to as a “silent killer” because the toxic particles in the air are gradually harming our bodies, especially for those with weak immune systems or pre-existing health conditions. This growing issue is leading to a rapid increase in respiratory and heart diseases, creating a dangerous situation.

    Dr. P.N. Arora, Chairman of Yashoda Super Specialty Hospital, Kaushambi, stated, “Air pollution negatively impacts the respiratory system. Pollutants enter the respiratory tract and cause diseases like asthma and bronchitis. Additionally, pollution also affects the heart and blood vessels. Air pollution causes inflammation in the blood vessels, leading to their hardening and causing circulation problems.”

    Dr. Arora further explained, “Pollution is also contributing to an increase in heart attacks, high blood pressure, and strokes. The micro-particles in the air raise blood pressure, which puts additional strain on the heart and blood vessels. Therefore, the effects of pollution are not limited to the respiratory system alone; it also impacts heart health.”

    To protect oneself from the harmful effects of air pollution, Dr. Arora recommended several preventive measures. He advised ensuring clean air at home by using air purifiers and keeping windows closed, especially during periods of high pollution. Maintaining a healthy diet rich in Vitamin C and antioxidants is essential to boost the immune system and provide protection against pollution. 

    Dr. Arora also emphasized the importance of exercise and spending time outdoors for fresh air, but only when the air quality is safe. Furthermore, regular health check-ups for heart and respiratory conditions are crucial, particularly for those living in areas with high pollution levels, to monitor and manage any potential health issues.

    Dr. Arora also emphasized that the government must take strict measures to reduce pollution to minimize the impact of this “silent killer.” This problem cannot be solved by individual efforts alone; collective action and spreading awareness are essential for all of us to address this issue together.

  • Aloe Vera To Snake Plant: Purifying Indoor Plants To Enhance Air Quality At Home – News18

    Aloe Vera To Snake Plant: Purifying Indoor Plants To Enhance Air Quality At Home – News18


    Last Updated:

    Apart from adding a touch of greenery to your living spaces, these indoor plants can also help in purifying the air quality of your house.

    NASA lists spider plant as one of the top three plants to have indoors.

    A thick layer of smog and haze engulfed the national capital this morning, raising the quality of air to the ‘severe’ category. The Air Quality Index (AQI) in Delhi breached the 400 mark at 9 AM, as per the Central Pollution Control Board (CPCB). This pressing issue has detrimental effects on health and well-being, leading to respiratory problems, heart diseases, and other health complications. While various measures are being taken to combat severe air pollution, it is important for Delhitees to improve indoor air quality through air-purifying plants.

    Here’s a handy list of houseplants that enhance indoor air quality while adding beauty and life to your living spaces.

    Aloe Vera

    Every household does own an Aloe Vera plant, thanks to its air-purifying capabilities and healing properties. This succulent plant is particularly effective at removing benzene and formaldehyde from indoor air. Do you know what’s the best part about this plant? It can tolerate a range of soil types and conditions, requires indirect sunlight, and requires very little watering. Besides its extensive air-purifying qualities, Aloe Vera has been used for centuries to treat burns, cuts, and other skin irritations.

    Snake Plant

    Popularly known for its exceptional air-purifying properties, this plant thrives in both light and dark places and does not require much care. Snake plant is a resilient and effective air purifier for purifying the air by removing formaldehyde, xylene, trichloroethylene, and benzene. It is also recognized for its nighttime oxygen-release properties. Another reason for its popularity is its striking upright leaves that can grow quite tall, reaching up to several feet in height.

    Spider Plant

    This plant is on the list of NASA’s top 3 houseplants, which are great at removing formaldehyde from the air. Spider plant is a fast-growing, easy-to-care-for houseplant that helps regulate carbon monoxide, formaldehyde, benzene, xylene, and nitrogen dioxide levels in the air. Its long, arching leaves and low maintenance requirements make it a popular choice among indoor gardeners. This plant prefers bright, indirect sunlight and relatively less watering, making them suitable for those who may forget to water their plants regularly.

    Bamboo Palm

    Another NASA-certified air-purifying plant is the Bamboo Palm. Similar to Aloe Vera, this plant is known to release oxygen at night and add moisture to the air. Not only this, this plant is also effective at filtering out toxins like benzene, formaldehyde, trichloroethylene, xylene, and chloroform. Bamboo palms can grow up to 12 feet tall, thrive in bright, indirect light, and prefer consistently moist soil. Regular watering is vital, especially during the growing season. With its elegant appearance and air-cleaning capabilities, it is an excellent choice for living rooms, offices, or any indoor space to add a touch of greenery.

    Peace Lily

    Known for its air-purifying capabilities and beautiful white flowers, peace lilies are a popular indoor plant that is highly effective at removing harmful toxins. It removes formaldehyde, benzene, and trichloroethylene from the air and requires relatively less care. Peace lilies prefer indirect sunlight and require regular watering to keep the soil moist. Moreover, peace lilies are known for their ability to regulate humidity levels in indoor spaces. Through a process called transpiration, they release moisture into the air, which helps alleviate dry skin and respiratory issues.

    Rubber Plant

    The rubber plant, also known as the rubber tree, is a large, striking houseplant that prefers bright, indirect light and should be watered when the top inch of soil is dry. It is great for removing formaldehyde and improving overall air quality. The large, glossy leaves and ability to grow quite tall add a touch of elegance to any room.

    Chinese Evergreen

    This plant emits a high oxygen content and purifies the air in the house by removing harmful chemicals such as formaldehyde and xylene. Chinese Evergreen also eliminates benzene, carbon monoxide, trichloroethylene, etc. It requires full shade and water in moderate quantities. The leaves of this plant turn a beautiful pinkish colour if left near a moderate to brightly lit window, providing lush foliage in your home spaces.

    Pothos

    The pothos, also known as the Devil’s Ivy, is excellent at filtering out formaldehyde, benzene, and xylene from indoor air. This fast-growing, trailing houseplant thrives in a variety of lighting conditions, making it a popular choice among indoor gardeners. Pothos plants are relatively easy to care for as they prefer bright, indirect light and should be watered when the soil is dry. One of the most appealing aspects is its long, vining stems that can climb up a trellis or be allowed to trail down from a hanging basket or shelf.

  • Air Pollution Can Affect Weight Gain And Hormonal Health; Check Experts Say On This

    Air Pollution Can Affect Weight Gain And Hormonal Health; Check Experts Say On This


    Amid poor air quality in the national capital, doctors on Friday warned that the air pollutants, besides causing respiratory and cardiovascular issues, can also lead to weight gain, contribute to rising obesity rates, and also affect hormonal health. 

    The air quality in Delhi-NCR on Friday morning was reported to be in the ‘very poor’ category with a thin layer of smog engulfing the region. According to the Central Pollution Control Board (CPCB), Delhi’s average air quality index (AQI) at 7.15 a.m. remained at 371.

    In seven areas of Delhi, the AQI level remained above 400 and between 450. The AQI was 410 in Anand Vihar, 411 in Bawana, 426 in Jahangirpuri, 402 in Mundka, 410 in Nehru Nagar, 402 in Shadipur, and 413 in Wazirpur.

    “Air pollution can affect weight gain by altering metabolism and can also affect hormonal health. Air pollution causes metabolic disorders that can lead to weight gain. It can also cause inflammation which leads to obesity,” Dr. Shailly Sharma, Senior Consultant and Associate Director, Obstetrician and gynaecologist, at Cloudnine Hospital, told IANS.

    “Air pollution can precipitate sedentary behaviour because it can cause certain respiratory symptoms like coughing, and shortness of breath, which can restrict physical activity and precipitate weight gain. It also increases insulin resistance, leading to weight gain and obesity,” Sharma said.

    Recent studies show that prolonged exposure to air pollution which contains particulate matter, nitrogen dioxide, and carbon monoxide, could lead to systemic inflammation and metabolic disturbances — key in weight gain and obesity.

    A meta-analysis published in BMC Public Health in July found that air pollution can impact metabolic function by influencing inflammation in fat tissue, increasing oxidative stress, and altering individual dietary habits.

    Breathing toxic air affects immune function and breathing pathways. This raises inflammation markers and increases oxidative stress.

    Dr. Vikas Mittal, Pulmonologist and director, Department of Respiratory Medicine, CK Birla Hospital told IANS that while there have been reports about air pollution affecting metabolism, leading to metabolic syndrome and obesity, the exact mechanism by which air pollution affects metabolism and hormonal health is not known.

    “It could be because air pollution is an irritant and it can cause inflammation in the airways, and then leads to the secretion of inflammatory markers in the body and blood, which then affects various organs, and thus can lead to increase the change in the hormonal milieu and increase in the pro-inflammatory markers. This can lead to worsening of cholesterol, high blood pressure, and diabetes — an important part of anybody having metabolic syndrome,” the doctor explained.

    Studies have shown that long-term exposure to the pollutants in the air can disrupt hormones, causing imbalance and also leading to reduced conception rates and overall fertility.

  • 10 Tips To Protect Your Heart Health During Smog Season – News18

    10 Tips To Protect Your Heart Health During Smog Season – News18


    Last Updated:

    The cold weather, coupled with increased pollution levels, can significantly impact heart health.

    While stepping outside, ensure you wear a mask to cover the nose and mouth.

    The onset of winter brings with it a host of health concerns, particularly for individuals with heart concerns. The cold weather, coupled with increased pollution levels, can significantly impact heart health. When we inhale polluted air, fine particulate matter (PM2.5), ozone, nitrogen dioxide, and other pollutants from vehicles, industrial sources, and factories, it can penetrate the respiratory system followed by the circulatory system. This causes inflammation in blood vessels, promotes plaque buildup, and leads to the hardening of arteries (atherosclerosis), increasing the risk of heart attacks and strokes.

    Therefore, it’s crucial to take proactive measures to protect your heart during this season. In this article, check out ten tips to safeguard your heart health during the winter season in India.

    Limit Outdoor Activities

    To improve your heart health, it is quite important to monitor air quality indexes (AQI) and stay indoors on days when pollution levels are high. Limiting outdoor activities will reduce exposure to harmful particles that can stress the heart and arteries.

    Wear A Mask

    While stepping outside, ensure you wear a mask to cover the nose and mouth securely. When selecting a mask, focus on three key factors: the mask’s ability to filter out particles smaller than 2.5 microns, the type of filter used, and the fit.

    Stay Hydrated

    Drink plenty of water to keep your body hydrated, especially during the winter months. Dehydration worsens the impact of air pollution on the cardiovascular system. When the body is dehydrated, the blood thickens, making it tougher for the heart to pump efficiently. This increases the risk of cardiovascular diseases such as heart attacks or strokes. Recognize the signals the body gives when the body is dehydrated, including dark urine, dizziness, or dry mouth, to help maintain proper water balance, reducing the strain on the heart.

    Monitor Blood Pressure

    With the increase in pollution levels, there is an increase in blood pressure levels, which places additional stress on the heart. Hence, it is essential to monitor your blood pressure regularly during smog season, particularly for individuals who have a history of hypertension or heart disease. Buy home blood pressure monitors and check blood pressure at the same time each day for consistency. Consult your healthcare provider if you notice significant spikes in high blood pressure during periods of poor air quality.

    Monitor Heart Stress Symptoms

    Pay close attention to symptoms that indicate that the heart is under stress during smog season. Shortness of breath, fatigue, chest discomfort, dizziness, and palpitations are all signs of cardiovascular issues. If you notice any of these symptoms, it is advised to seek medical attention immediately. Document symptoms that can help correlate symptoms with pollution exposure.

    Schedule Regular Health Checkups And Cardiac Screening

    Visit your healthcare provider and schedule regular ECG tests, particularly during or after smog season, to identify any early signs of heart stress. An electrocardiogram (ECG) provides a more comprehensive picture of the electrical activity of the heart, making it essential for detecting irregular heart rhythms and other cardiovascular issues. Although some wearable devices offer ECG functionality, professional evaluation remains critical if symptoms such as fatigue, chest pain, or irregular heartbeats occur.

    Maintain A Healthy Diet

    Consume a heart-healthy diet rich in antioxidants, omega-3 fatty acids, and fibre, such as fruits, vegetables, fish, and whole grains. It helps mitigate the effects of air pollution, reduce inflammation, and support heart health. Moreover, add more anti-inflammatory foods like leafy greens, berries, and nuts to your diet.

    Regular Exercise

    Engage in regular physical activity for heart health, but avoid excessive exertion, especially in cold weather. During days with high pollution, consider shifting your workout indoors in well-ventilated spaces or air-purified rooms to avoid inhaling polluted air that can negate the benefits of exercise.

    Use An Air Purifier

    Invest in a high-quality air purifier, especially when you have the elderly, children, and pregnant women at home. Air purifiers can significantly reduce indoor pollutants and improve air quality, ensuring cleaner air in bedrooms and living areas where people spend the most time. Ultimately, it protects your cardiovascular system from prolonged exposure to airborne toxins.

    Track Local Air Quality

    Another thing to follow during this chilling weather is keeping an eye on air quality levels. It is one of the most effective ways to reduce exposure to harmful pollutants. Stay informed about the air quality in your area through various apps and online tools such as AirVisual or AQICN, which provide real-time updates on pollution levels. The AQI is an easy-to-understand rating system that ranks pollution from ‘good’ to ‘hazardous.’ When you see the AQI reaches unhealthy levels (typically at 100 or above), it’s best to limit outdoor activities as it helps minimize the cardiovascular strain caused by inhaling fine particles and gases.

    How Factory Pollution May Be Linked To Unexpected Snowfall | Explained – News18


    Last Updated:

    A study by scientists found that industrial pollution can trigger a phenomenon that results in more snowfall in nearby areas.

    In recent years, Delhi has been grappling with hazardous levels of air pollution, especially during the colder months. The combination of industrial pollutants and fog often results in poor visibility, creating serious health risks for residents. However, a recent scientific study has revealed an unexpected consequence of this pollution: snowfall. It turns out that emissions from factories may be influencing local weather patterns, leading to more frequent snowfall in areas close to industrial sites. Here’s how it works and what this means for the environment.

    Pollution and Snowfall: An Unlikely Connection

    The air quality in Delhi, and many other industrial areas around the world, is deteriorating due to increased pollution from factories, power plants, and other industrial sources. While the air may seem to clear up momentarily when it rains, new research suggests that this could also be linked to snowfall – but not in the way most people would expect.

    A study conducted by an international team of scientists found that industrial pollution, specifically the tiny particles emitted by factories, can trigger a phenomenon that results in more snowfall in nearby areas. This happens through a process known as cloud glaciation, which takes place under specific temperature conditions.

    How Factory Pollution Triggers Snowfall

    Clouds typically form when water vapour condenses into droplets. In colder conditions, these droplets can freeze and form ice crystals, creating snow. However, this process doesn’t always occur naturally. The new study suggests that pollutants, such as aerosols emitted by factories, can play a crucial role in this transformation.

    When the temperature drops between -10°C and -24°C (14°F to -11°F), these pollutants serve as ‘nuclei’, providing a surface on which water droplets can freeze. This is known as cloud glaciation. The study also highlights that emissions from industries, including coal-fired power plants, can release heat and water vapour into the atmosphere, which might further contribute to the process.

    Unexpected Snowfall Around Industrial Sites

    Researchers observed satellite images of clouds near 67 industrial sites, analysing near-infrared data from NASA’s Terra satellite. The data revealed something unusual: while clouds were forming, they were not composed of the typical liquid water droplets. Instead, the pollution-laden clouds were turning into ice clouds, even in places where such snowfall wouldn’t usually occur.

    In fact, snowfall levels in these areas were higher than in surrounding regions, with snowfall reaching up to 15 mm (over half an inch) in some cases. The intensity of the snowfall was also greater, averaging 1.2 mm per hour. This means that, in some cases, industries are not just contributing to air pollution but may also be causing significant weather changes in their immediate surroundings.

    Potential Health and Environmental Impacts

    The findings are concerning for both public health and the environment. While the harmful effects of air pollution have been well-documented, this new research suggests that the pollutants from factories could also lead to unexpected weather events, like snowstorms, in areas that might not typically experience such conditions.

    Professor Nicolas Bellouin, one of the study’s co-authors, pointed out the broader implications: “We already knew about the health effects of air pollution, but now we know that emissions from factories can turn rain clouds into ice clouds. This can lead to unexpected snowfall that does not occur in other areas.” The impact of such snowfall could be severe, particularly for local communities who might not be prepared for heavy snowfalls in the middle of winter.

    Snowfall Threat That Could Affect Larger Areas

    In some cases, the snowfall generated by industrial pollution could cover large areas. A single snow event could potentially drop more than 1.3 cm (half an inch) of snow over an area larger than a typical city. This raises concerns for people living near industrial sites, who may need to adapt to the possibility of sudden snowstorms.

    There’s also a broader environmental concern at play. Clouds are known to play a crucial role in reflecting sunlight back into space, helping to regulate the Earth’s temperature. Ice clouds, however, reflect less sunlight than liquid clouds, meaning that as more ice clouds form, they could contribute to changes in global weather patterns.

    Need for More Research

    While the study’s findings provide compelling evidence of the connection between factory pollution and snowfall, the researchers emphasise that more research is needed. Understanding how industrial pollutants affect cloud formation and precipitation is complex, and scientists are keen to explore the full extent of their impact on the global climate.

    The study, published in *Science*, concludes that aerosols from industrial sites may have a far-reaching impact on both local weather and the wider climate system. However, much remains to be understood about how these particles interact with clouds and what long-term consequences they might have for our environment.

    This new research provides valuable insight into the unexpected consequences of industrial pollution, shedding light on the complex relationship between air quality and weather. While the snow generated by pollution may seem like a minor inconvenience, its implications for public safety, health, and the environment could be far-reaching. As the study shows, it’s not just the air we breathe that’s at risk – it’s also the weather patterns that affect our daily lives. With further research, we may better understand how to mitigate these effects and prepare for the impact of pollution-driven snowfall.

    Study Links Increased PM10 Exposure To Higher Risk Of Eye Infections And Ocular Conditions


    New Delhi: People living in areas with increased exposure to PM10 can be at twice more risk of suffering eye infections, according to a study in the US. 

    Researchers from the University of Colorado Anschutz Medical Campus showed that clinical visits by patients suffering ocular surface eye conditions more than doubled when ambient particulate matter from air pollution was in the atmosphere.

    Ocular surface disease (OSD) is a group of eye conditions that affect the surface of the eye, including the cornea, conjunctiva, and eyelids.

    “The World Health Organization has declared climate change to be “the single biggest health threat facing humanity,” said lead author Jennifer Patnaik, Assistant Professor of epidemiology and ophthalmology at the University of Colorado School of Medicine.

    “Yet there are limited studies on the impact of climate change-related air pollution on ocular health,” Patnaik added.

    In the study, the team examined the link between ocular surface irritation and allergy-related daily outpatient office visits with daily ambient particular matter (PM) levels in the Denver Metropolitan area.

    About 144,313 ocular surface irritation and allergy visits to ophthalmic clinics were recorded.

    The daily visit counts were 2.2 times higher than average when PM10 concentrations were 110. The clinic visit rate ratio increased as daily concentrations increased, the researchers said. Notably, conjunctivitis represented one-third of all the visits.

    The study, published in the journal Clinical Ophthalmology, is among the first to look into how climate change may affect the eyes.

    Patnaik said the health risks of air pollution and climate change span a wide range of outcomes including infectious disease, weather-related morbidity, and a variety of lung, kidney, and cardiovascular maladies.

    The study may also be significant for India, even as the northern areas continue to suffer from severe air pollution.

    For the fourth consecutive day, the national capital continues to battle a worsening pollution crisis, with its air quality plunging into the ‘severe’ category.

    A dense smog has blanketed the city, with the Air Quality Index (AQI) recorded at 406 on Saturday morning, according to the Central Pollution Control Board (CPCB).

    The smog and pollution are also causing other health concerns, including respiratory distress, and heightened risks of cardiovascular complications.
