This assessment report summarises current scientific knowledge on transboundary air pollution issues within the UNECE region and describes the effectiveness of air pollution measures in addressing large-scale effects on forests and lakes as well as in protecting human health and preventing other air pollution effects, such as loss in biodiversi

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 moni

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.

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 ris

MEXICO CITY — Mexico City authorities have lifted a smog alert one day after ozone levels rose above 150 percent of acceptable limits.

The Government of National Capital Territory of Delhi had implemented oddeven scheme from 15th to 30th April, 2016.

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

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.

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 datasets and accumulated daytime hourly O3 concentration over a threshold of 40 ppbv (AOT40) indices to estimate crop yield damage resulting from ambient O3 exposure.

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 new report has warned.
