Surface ozone pollution remains stubbornly persistent even as emissions of traditional precursors decline. New research reveals that oxygenated ...

An international effort to measure air quality in South Korea, a region with complex sources of pollution, may provide new insights into the atmospheric chemistry that produces ozone pollution, ...

We humans spend the vast majority of our time indoors, and we are constantly bombarded with compounds emitted from environmental sources. But we aren’t just passive targets of a chemical barrage. Our ...

Irvine, Calif., June 13, 2006 -- Standard methods of predicting air pollution don't take atmospheric chlorine into account, but the chemical could be responsible for 10 percent or more of daily ozone ...

Haze is formed when a cocktail of various gaseous pollutants is oxidized and forms particulate matter diffusing sunlight. This process is mainly mediated by hydroxyl radicals (OH), and researchers ...

An international team of researchers has found that while indoors, people are exposed to various chemicals from the atmosphere, including reactive chemicals emitted directly from human skin and breath ...
