Excessive ozone gas has become the prime pollution problem in Beijing in recent days, replacing the notorious PM2.5, and it's likely to linger for a couple of days, the capital's environmental monitoring authority said on Monday. Because of the sunshine, many residents may not have noticed that ozone reached an …
Efforts to reduce dangerous air and climate pollutants by Latin American and Caribbean (LAC) countries could reap immediate and long-term benefits for health, food security and the climate according to the first ever Integrated Assessment of Short-lived Climate Pollutants (SLCPs) for the region. The assessment, released by the United Nations …
India can enhance its rice yields by 2.5 percent and wheat by 3.3 percent if emissions leading to generation of ground-level ozone could be mitigated, say scientists who have developed an ozone risk estimate database. It could aid policymakers examine suitable mitigation strategies for crop protection against ozone pollution, they …
MEXICO CITY — Mexico City authorities have lifted a smog alert one day after ozone levels rose above 150 percent of acceptable limits. A statement from the metropolitan area's environmental commission said favorable weather conditions Sunday morning and rains in the afternoon led to a reduction. The alert had banned …
The Government of National Capital Territory of Delhi had implemented oddeven scheme from 15th to 30th April, 2016. As per as Direction of Hon’ble NGT, ambient air quality of Delhi was monitored through a set of Continuous Ambient Air Quality Monitoring Systems (CAAQMS) and manual stations (NAMP) spread across different …
Scientists say they have made a startling discovery about the link between domestic oil and gas development and the world’s levels of atmospheric ethane — a carbon compound that can both damage air quality and contribute to climate change. A new study in the journal Geophysical Research Letters has revealed …
Levels of tiny pollution particles (PM 2.5) are relatively lower now than in winter. But there is no relief from dirty, toxic air in the city. With the summer heat rising, ozone (O3) levels are breaching the safe standard at several locations in the city. O3 levels were the highest …
In this study, we evaluate the potential impact of ground level ozone (O3) on rice and wheat yield in top 10 states in India during 2005. This study is based on simulated hourly O3 concentration from the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem), district-wise seasonal crop production …
More than half of the US population lives amid potentially dangerous air pollution, with national efforts to improve air quality at risk of being reversed, a new report has warned. A total of 166 million Americans live in areas that have unhealthy levels of of either ozone or particle pollution, …
American Lung Association’s ‘state of the air’ report finds 166 million Americans are living in unhealthy ozone or particle pollution with serious health risks. More than half of the US population lives amid potentially dangerous air pollution, with national efforts to improve air quality at risk of being reversed, a …
The present study examines the role of tropical cyclones in the enhancement of tropospheric ozone. The most significant and new observation reported is the increase in the upper-tropospheric (10–16 km) ozone by 20–50 ppbv, which has extended down to the middle (6–10 km) and lower troposphere ( < 6 km). …
Millions of people in Mexico City are choking on the worst air quality in 14 years, as cars and trucks add to the pollution with their outdated emissions controls. And it’s not as though Mexico lacks access to the best technology. The nation’s export-oriented factories, the focus of a $20 …
Data published by the town hall here on Tuesday shows the Spanish capital registered levels of pollution above those fixed by the World Health Organization (WHO) for "all primary contaminants" except ozone for 2015. A total of 13 of the 24 stations situated in Madrid to measure pollution levels showed …
We develop a statistical model using extreme value theory to estimate the 2000-2050 changes in ozone episodes across the United States. We model the relationships between daily maximum temperature (Tmax) and maximum daily 8-hour average (MDA8) ozone in May-September over 2003-2012 using a Point Process (PP) model. At ~20% of …
Authorities in Mexico City have temporarily ordered all cars to remain idle one day a week in response to this notoriously smoggy capital’s worst air-quality crisis in over a decade. Until now vehicles have been exempt from the Mexican capital’s “no circulation” rules if owners obtain a holographic sticker from …
Mexico City's government ordered traffic restrictions on Tuesday and recommended people stay indoors due to serious air pollution, issuing its second-highest alert warning for ozone levels for the first time in 13 years. While conditions persisted, residents were better off inside between 1 pm and 7 pm, should refrain from …
Adults with long-term exposure to ozone (O3) face an increased risk of dying from respiratory and cardiovascular diseases, a study “Long-Term Ozone Exposure and Mortality in a Large Prospective Study” published online ahead of print in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine suggests. Using …
Having announced another round of odd-even driving in April, the Delhi government has to gird itself for a crucial test. Particulate matter (PM) levels are usually "moderate" to "poor" during the warm season, but ozone emissions, which are linked with respiratory problems, go up dramatically when vehicular and other emissions …
