Bad air pervades in half of Chinese cities

Oct 24 ,Space & Earth science


China said Tuesday air quality is moderately or seriously polluted in nearly half of its cities, with particulate matter being the chief culprit.

The state Environmental Protection Administration said most urban citizens are living with excessive particulate matter in the air, reports Xinhua news agency. The agency said in cities with more than 1 million people, sulfur dioxide and particulate matter are the top pollutants.

"About 48.1 percent of Chinese cities are suffering from moderate or serious air pollution," SEPA Deputy Director Zhang Lijun told a workshop meeting.

His agency suggested that China along with the United States and the European Union should set up a coordinated air quality surveillance system.

Mountain pine beetles appear to be doing more than killing large swaths of forests in the Rocky Mountains. Scientists suspect they are also altering local weather patterns and air quality.

National study examines health risks of coarse particle pollution
Researchers at the Johns Hopkins Bloomberg School of Public Health have conducted the largest nationwide study on the acute health effects of coarse particle pollution. Coarse particles are airborne pollutants that fall between 2.5 and 10 microns in diameter. These particles are larger than fine particles (less than 2.5 microns) and are produced by processes such as mechanical grinding, windblown dust and agriculture. These particles are of interest from both public health and regulatory perspectives.
Link between ozone air pollution and premature death confirmed
Short-term exposure to current levels of ozone in many areas is likely to contribute to premature deaths, says a new National Research Council report, which adds that the evidence is strong enough that the U.S. Environmental Protection Agency should include ozone-related mortality in health-benefit analyses related to future ozone standards. The committee that wrote the report was not asked to consider how evidence has been used by EPA to set ozone standards, including the new public health standard set by the agency last month.
Black carbon pollution emerges as major player in global warming
Black carbon, a form of particulate air pollution most often produced from biomass burning, cooking with solid fuels and diesel exhaust, has a warming effect in the atmosphere three to four times greater than prevailing estimates, according to scientists in an upcoming review article in the journal Nature Geoscience.
