Order of the National Green Tribunal in the matter of News Item titled “CSE report finds dangerous increase in ozone pollution across urban India” appearing in Down to Earth dated 06.08.2024. The Principal Bench of the NGT heard the matter on March 21, 2025. In the original application, registered suo …
WMO has published the first issue in the 2015 series of the Antarctic Ozone Bulletin, with information on the state of the ozone layer in Antarctica and surrounding areas. Measurements with ground-based instruments and with balloon sondes from some stations in the Global Atmosphere Watch network show first signs of …
A new study has suggested that use of ozone-tolerant cultivars can enhance the food security of India. University of Eastern study highlighted the current status of ozone research in the Indo-Gangetic Plains (IGP), which have been classified as a "hot spot" for air pollution, that is agriculturally important and densely …
BEIJING - Ozone overtook PM2.5 to become the main air pollutant in China in July, and may remain so until the end of October, according to a report released Monday. China sees a regular pattern in terms of the regional and seasonal distribution of ozone -- the density is higher …
Particulate matter and NO2 air pollution are associated with increased risk of severe heart attacks despite being within European recommended levels, according to research presented at ESC Congress today by Dr Jean-Francois Argacha, a cardiologist at University Hospital Brussels (UZ Brussel-Vrije Universiteit Brussel), in Belgium. "Dramatic health consequences of air …
ARIES, acronym for Aryabhatta Research Institute of Observational Sciences, located in the Central Gangetic Himalayan (CGH) region is emerging as one of the unique sites for climate change studies. The long-term, in situ, precise measurements of aerosols and trace gases obtained from this region provide valuable inputs for climate studies. …
Nitrogen oxides, released from fossil fuel use and other combustion processes, affect air quality and climate. From the mid-1990s onward, nitrogen dioxide (NO2) has been monitored from space, and since 2004 with relatively high spatial resolution by the Ozone Monitoring Instrument. Strong upward NO2 trends have been observed over South …
The Kathmandu Valley in South Asia is considered as one of the global "hot spots" in terms of urban air pollution. It is facing severe air quality problems as a result of rapid urbanization and land use change, socioeconomic transformation and high population growth. Original Source
China has recently made available hourly air pollution data from over 1500 sites, including airborne particulate matter (PM), SO2, NO2, and O3. We apply Kriging interpolation to four months of data to derive pollution maps for eastern China. Consistent with prior findings, the greatest pollution occurs in the east, but …

Grimy city buildings and statues aren’t just unsightly, they also contribute to smog. A new study says sunlight triggers the release of smog-forming nitrogen oxide compounds from dirt coating buildings and statues in urban areas. And this process may be a surprisingly significant contributor to air pollution in cities. The …
PARIS – Progress slashing unhealthy ozone in the western United States has largely been undone by pollution wafting across the Pacific from China, according to a study published Monday. Scientists have long suspected this might explain why ozone levels along the U.S. west coast remained constant despite a significant local …
Harmful ozone pollution in Shanghai over the past 12 days has reached levels that are 1.5 times higher than the World Health Organisation’s recommended limit. Pollution from the toxic gas has now replaced PM2.5 particulates – minute chemical particles suspended in the air with diameters no bigger than 2.5 microns …
Question raised in Lok Sabha on pollution from ozone/black carbon, 04/08/2015. A research paper on ‘Recent climate and air pollution impacts on Indian agriculture’ has been published in Current Issue of the Proceedings of the National Academy of Sciences of the United States of America in November 2014. As per …
Air pollution in many national parks, from Yosemite to Joshua Tree and Kings Canyon, means a hike in the ‘fresh air’ is not as healthy as it seems, reports Mother Jones It’s late summer, and Americans are flocking to the country’s national parks for some recreation and fresh air. But …
Imagine asking your phone to calculate the optimal route for cycling to work while enjoying the best air quality, or calculating whether it's better to just take the train or bus to reduce pollution. Similar requests might soon be possible. On Tuesday, Google and Aclima, a San Francisco-based startup that …
Millions of vacationers escape to national parks each summer to take in the fresh air and scenic vistas. But a report released Tuesday by a conservation group finds that some of the nation’s most treasured landscapes are plagued with polluted air and hazy skies — and remain decades behind schedule …
We’ve come to rely on Google Street View for everything from roads to hiking paths to coral reefs, but we may soon rely on it for something even more important – mapping urban air pollution. Tech startup Aclima just announced a partnership with Google Earth Outreach to equip Google Street …
CHINA saw a modest improvement in the levels of two common air pollutants in the first half of the year, environmental group Greenpeace East Asia said yesterday. Average levels of PM2.5 — the tiny particles that can penetrate deep into the lungs and are particularly hazardous to human health — …
In a report titled 'State of the Climate in 2014,' the American Meteorological Society has described 2014 as the warmest year on record. The World Meteorological Organization (WMO) has also reported that the January-June 2015 period was the hottest on record, citing figures provided by the National Atmospheric and Oceanic …
When Hamish Stewart bikes the streets of London, he clips a tiny digital device to his shirt collar or pants pocket. The wearable technology isn’t tracking the distance he travels or the calories he burns: Instead, it measures how many toxic pollutants from cars, buses and factories are sullying Stewart’s …
