Indiana University, EPA to study airborne PCBs
BLOOMINGTON, Ind. -- The elevated PCB levels in U.S. lakes and rivers that led to hundreds of U.S. Environmental Protection Agency fish consumption advisories in 2003 may be the result of not only the toxin's persistence underground but also its diffusion through the air....... To investigate the phenomenon, the EPA announced today (Sept. 27) that it would continue its collaboration with Indiana...Carnegie Mellon researcher tests tools for protecting Anacostia River ecosystem from PCBs
PITTSBURGH-- A sediment-capping mat developed by Carnegie Mellon engineers and CETCO (Arlington Heights, IL) soaks up dangerous PCBs (polychlorinated biphenyls) and could prevent their long-term release into waterways, according to the researchers, who are evaluating it in field trials in Washington D.C.'s contaminated Anacostia River. ...In hundreds of contaminated waterways across the country,...Carnegie Mellon scientists reveal ways of studying, resolving PCB contamination in US rivers
PHILADELPHIAThe distribution and movement of PCBs (polychlorinated biphenyls) in the environment has threatened scarce water supplies, ecosystems, tourism and the world's fragile fishing industry. In the three decades since PCB production and use were banned, sediments of many lakes and waterways continue to provide a source of these deadly toxins to the water and ultimately to fish and people....PCB breakdown in rivers depends on sediment-specific bacteria, find Carnegie Mellon U. scientists
One of Mother Nature's most promising weapons to break down persistent, toxic polychlorinated biphenyls (PCBs) is bacteria. Now, a study by Carnegie Mellon University scientists provides convincing evidence that how quickly a PCB gets eaten and what it becomes depends on where it settles. Using DNA fingerprinting, the Carnegie Mellon team discovered distinct bacterial populations in the first-eve...Latest findings on PCBs to be subject of June workshop at Illinois
CHAMPAIGN, Ill. -- Some 200 scientists from around the world will gather June 13-15 at the University of Illinois at Urbana-Champaign to discuss their latest findings on the health effects of exposure to PCBs (polychlorinated biphenyls) -- long-lasting chemicals manufactured and widely used before being banned or restricted since the late 1970s.... ...The talks at the will be review...New study suggests that women eating PCB contaminated fish are less likely to give birth to boys
New research published in the open access journal, Environmental Health: a Global Access Science Source suggests that women exposed to polychlorinated biphenyls are less likely to give birth to boys. The results come from a study of mothers and fathers around the Great Lakes region of the United States who have eaten large quantities of contaminated fish. These findings add to a growing body of e...Researchers close in on natural solution to PCB contamination
WEST LAFAYETTE, Ind. -- An environmentally friendly solution to one of the world's most notorious chemical contamination problems may be a step closer to reality, reports a research team from Purdue University and the University of British Columbia. ......The team has identified one of the key stumbling blocks that prevent microorganisms from decomposing PCBs (polychlorinated biphenyls), a persis...Sunlight, PCB exposure enhance skin cancer chances
CHAMPAIGN, Ill. Sunlight and PCB exposure can hit you where you least expect it. The combination enhances the development of non-melanoma skin cancer on parts of the body not directly exposed to the sun, according to a University of Illinois study.... Preliminary results of the research, which used the hairless mouse model of humans with non-malignant skin cancer, were presented today (March 2...Men with higher levels of PCBs more likely to father boys
A Michigan State University study indicating that men with higher levels of PCBs in their bodies are more likely to father boys than girls is more evidence of the effects environmental contaminants can have on the human body. ...... The study, using data from three separate studies in which PCB levels were measured in the bodies of men who ate fish taken from Lake Michigan, found that of the 208...Microbe first to break down PCBs
BALTIMORE, Md. --A first strain of bacterium that breaks down tough chlorine bonds of the pollutant PCBs, polychlorinated biphenyls, in estuarine sediment is reported in the current issue of the journal Environmental Microbiology by scientists with the University of Maryland Biotechnology (UMBI). ... In experiments repeated many times on bottom sediments from Baltimore harbor, researchers of UMB...PCB exposure is bad news for the female sex drive
.Female rats that are exposed to PCBs in the womb are reluctant to mate as.adults. This raises the possibility that similar chemical contaminants can cause.low sex drives in women. . . PCBs are a group of stable chemical additives once widely used in the.production of pesticides, lubricants and plastics. Their use was banned in many.countries after it became clear that some PCBs mimic hor...Breast Milk Of Women Who Eat Lake Ontario Fish Contains High Levels Of PCBs, UB Study Finds
. BUFFALO, N.Y. -- Women who eat fish from Lake Ontario have significantly.higher levels of PCBs and pesticides in their breast milk than women who do not.eat Lake Ontario fish, results of a study of lactating women in the New York.State Angler Cohort has shown.. .

BUFFALO, N.Y. -- A new study of the relationship of pesticides and PCBs with breast cancer shows that these compounds are not a risk factor for breast cancer for the general population of women. . Researchers at the University at Buffalo found that blood levels of organochlorines -- such as DDE, HCB, mirex and PCBs -- were not higher in women with breast cancer than in healthy women. ....
