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...

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...

Unique database of agricultural pesticide application records informs research FREMONT, Calif., Sept. 24 /PRNewswire-USNewswire/ -- Northern California Cancer Center (NCCC) research reveals that children exposed to agricultural pesticides applied near their home may experience an increased risk of the most common form of childhood leukemia. The NCCC study, led by Rudolph Rull, Ph.D., used a database unique to California to reveal an elevated risk in acute lymphoblastic leukemia (ALL) among...

Scientists say the four-day testing period the U.S. Environmental Protection Agency uses to determine safe levels of pesticide exposure is too short. The University of Pittsburgh researchers said they found the highly toxic pesticide endosulfan -- a neurotoxin banned in several nations, but still used extensively in U.S. agriculture -- can exhibit a lag effect with the fallout from exposure not occurring until after direct contact has ended. The team that included lead author Devin Jones,...

 Although it is known that infants are more susceptible than adults to the toxic effects of pesticides, this increased vulnerability may extend much longer into childhood than expected, according to a new study by researchers at the University of California, Berkeley.Among newborns, levels of paraoxonase 1 (PON1), an enzyme critical to the detoxification of organophosphate pesticides, average one-third or less than those of the babies' mothers. It was thought that PON1 enzyme activity in...

WASHINGTON, June 18 /PRNewswire-USNewswire/ -- Farmworker unions, support groups, and worker advocacy organizations today asked Environmental Protection Agency (EPA) Administrator Lisa P. Jackson to stop the pesticide poisoning of farmworker communities and uphold the Obama administration's commitment to environmental justice. Citing a long EPA history of "inhumane neglect of toxic pesticide effects on farmworker community health," the groups asked the Administrator to amend a recent May 2009...

 The cause of Parkinson's disease (PD), the second most frequent neurodegenerative disease after Alzheimer's disease, is unknown, but in most cases it is believed to involve a combination of environmental risk factors and genetic susceptibility. Laboratory studies in rats have shown that injecting the insecticide rotenone leads to an animal model of PD and several epidemiological studies have shown an association between pesticides and PD, but most have not identified specific pesticides...

U.S. scientists say they have discovered marine mammals are being exposed to a cocktail of pesticides, as well as new contaminants. In what's called the most extensive study of pollutants in marine mammals' brains, Woods Hole Oceanographic Institute scientists found the animals are exposed pesticides such as DDT and PCBs, as well as contaminants such as brominated flame retardants. Eric Montie, lead author of the study, performed the research in collaboration with Mark Hahn and Chris Reddy of...
