Researchers have reported that the melting Alpine glaciers are letting off harmful pollutants once captured by the ice, which could result in a "dire environmental impact" for the region. In a study of sediment from an Alpine lake, Swiss researchers found trace amounts of now banned chemicals such as dioxins and pesticides like DDT. "We can confirm with the help of these layers that, in the 1960s and 1970s, POPs (Persistant Organic Pollutants) were produced in great quantities and were also...

Plumes of harmful air pollutants can be transported across oceans and continents -- from Asia to the United States and from the United States to Europe -- and have a negative impact on air quality far from their original sources, says a new report by the National Research Council.  Although degraded air quality is nearly always dominated by local emissions, the influence of non-domestic pollution sources may grow as emissions from developing countries increase and become relatively more...

Pollutant plumes observed in the United States can be attributed unambiguously to Asian sources based on meteorological and chemical analyses, researchers say. Charles Kolb -- president of Aerodyne Research Inc. and chairman of the committee that wrote the report on air pollution by the National Research Council -- said the report examines four types of air pollutants: ozone; particulate matter such as dust, sulfates, or soot; mercury; and persistent organic pollutants such as DDT. The...

 A scientific trend to view the world's biggest cities as analogous to living, breathing organisms is fostering a deep new understanding of how poor air quality in megacities can harm residents, people living far downwind, and also play a major role in global climate change. That's the conclusion of a report on the "urban metabolism" model of megacities presented here today at the 238th National Meeting of the American Chemical Society (ACS).Charles Kolb, Ph.D., reports that the concept...

According to Lisa Jackson, administrator of the U.S. Environmental Protection Agency, the government will reverse a Bush administration policy and increase the role of scientists in creating air standards for pollutants. The EPA will reinstate a policy document called "staff paper" written by agency scientists that analyzes options for the EPA to consider when creating air standards. The staff paper process was replaced with a notice of proposed rule-making which outlined options for air...

We are used to thinking of heart disease as a product of genetic factors or lifestyle choices, such as what we eat and how much we exercise. There is another road to heart disease: breathing. Accumulating evidence indicates that an increase in particulate air pollution is associated with an increase in heart attacks and deaths. Research has begun in the relatively new field of environmental cardiology -- a field that examines the relationship between air pollution and heart disease. Aruni...

Broken System Allowing a Few Legislators to Hold Up Budget Must Be Fixed SACRAMENTO, Calif., Feb. 19 /PRNewswire-USNewswire/ -- Environmental Defense Fund (EDF) today called for reforms to prevent a minority of legislators acting on behalf of special business interests from demanding policy changes that are irrelevant to the budget process resulting in lengthy, painful and costly delays. One possible solution to prevent costly budget stalemates is repealing California's unique status as one...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...
