For the first time, researchers have identified two important strategies for optimizing the effects of the enzymes involved in degrading persistent pollutants such as PCBs. These scientific advances, achieved by Professor Michel Sylvestre of Centre INRS—Institut Armand-Frappier in conjunction with U.S. and Indian researchers, will serve not only to help develop effective biocatalysts for resolving environmental pollution problems, but also to synthesize new chemical compounds of...

Chemicals found at low levels at all sites tested URI researcher: 'Emerging contaminants of concern' detected throughout Narragansett Bay watershed A group of hazardous chemical compounds that are common in industrial processes and personal care products but which are not typically monitored by the Environmental Protection Agency have been detected throughout the Narragansett Bay watershed, according to a URI researcher. Rainer Lohmann, associate professor of chemical oceanography,...

The technology in "fire paint" used to protect steel beams in buildings and other structures has found a new life as a first-of-its-kind flame retardant for children's cotton sleepwear, terrycloth bathrobes and other apparel, according to a report presented here today at the 242nd National Meeting & Exposition of the American Chemical Society (ACS). "People are concerned about the potential toxicity of flame retardants that are currently used on a variety of products, especially...

  Exposure during pregnancy to flame retardant chemicals commonly found in the home is linked to lower birthweight babies, according to a new study led by researchers at the University of California, Berkeley's School of Public Health. In the study, published Tuesday, Aug. 30, in the peer-reviewed publication American Journal of Epidemiology, researchers found that every tenfold increase in levels of PBDEs, or polybrominated diphenyl ethers, in a mother's blood during pregnancy...

A new study finds that pregnant women in Northern California have the highest PBDE flame retardant exposures reported to date among pregnant women worldwide. It also describes some of the first evidence from humans that certain flame retardants may interfere with thyroid hormone signaling during pregnancy, which is critical to fetal brain development. The study, described as one of the most extensive to date on flame retardant exposures in pregnant women, appears in the ACS journal...

Toxic chemicals that have been trapped in Arctic ice and snow are now being released due to global warming, according to a study published on Sunday. Researchers warn that the amount of poisons in the polar region is unknown and the release of large amounts of such poisons could "undermine global efforts to reduce environmental and human exposure to them." Those chemicals include the pesticides DDT, lindane and chlordane; and industrial chemicals PCBs and HCB. All of these are known as...
