Chemicals pumped into the air by fossil fuels create smog-forming chlorine atoms that boost ozone levels, researchers in California said. Under extreme circumstances, the chemicals could account for nearly half of California's state-set limits on outdoor air pollution, scientists at the University of California, Irvine, said Monday in a release. We should be monitoring it and incorporating it into atmospheric models, chemistry professor Barbara Finlayson-Pitts said. We still don't really...

La Plata/Leipzig. Increasing numbers of children around the world are suffering from respiratory problems "“ coughing, wheezing and asthma attacks. Although the key external causes of these diseases were identified a long time ago (traffic and industrial air pollution), it had not previously been possible to distinguish clearly between these two factors so as to have a targeted impact on them. Researchers at the Helmholtz Center for Environmental Research (UFZ) and the University of...

University of Leicester researcher probes role of hydrogen sulphide Scientists at the University of Leicester are investigating how the stuff of stink bombs and flatulence could play a critical role in the human reproductive system. Hydrogen sulphide "“partially responsible for the foul odor of stink bombs- is also a toxic gas and has been used for chemical warfare. But research at the University of Leicester is now looking at beneficial effects it has in the body- and the potentially...

U.S. researchers found particulate air pollution in Beijing was far worse than other recent Olympic Games. The study, published in Environmental Science and Technology, was done before, during and after the 2008 Olympics by scientists from Oregon State University and Peking University. Particulate matter air pollution in the Beijing Olympics were about double the levels of recent games in Athens, triple those of Atlanta and 3.5 times higher than the games in Sydney. However due to massive...

FARGO, N.D., April 29 /PRNewswire-USNewswire/ -- As cleanup from this year's record floods continue in the Fargo-Moorhead region, a new report from the American Lung Association is providing the city some badly needed good news. Fargo was the only city to be listed as the best cities for ozone pollution, short-term particle pollution and long-term particle pollution. According to the report, more than 40 million Americans live in areas that failed all three tests. The rest of the state...
