Mathematically determining exposure levels of chemicals, PCBs effects on cochlear function, PAH concentrations from salmon smoking, arsenic in well water, and mountaintop mining dust are highlighted this week.

and Richard Judson, alongside colleagues, have developed a mathematical model to help predict the household and industrial chemicals to which people are most exposed. As published in Environmental Science & Technology, the researchers analyzed 8,000 chemicals and found that some of the ones with the highest potential exposure levels have not been extensively studied.

PCB.pngNew research in Environmental Health Perspectives, featuring Marc-André Verner as one of the authors, indicates postnatal exposure to polychlorinated biphenyls (PCBs) causes a minor change in children’s cochlear function. In the article accompanying the research, Susan Schantz indicates this research may have implications for other areas, such as research into language development.

Increases in hydroxylated PAH concentrations were discovered in urine samples of members of the Confederated Tribes of Umatilla Indian Reservation after six hours of fish smoking, according to new research in Science of the Total Environment. To conduct the research, David Stone and his colleagues had to develop an analytical method to measure 19 PAHs and 34 hydroxylated PAHs.

Author and columnist Deborah Blum’s latest article for The New York Times focuses on arsenic levels in drinking water, specifically focusing on the issue of private wells. She interviewed many experts, including Aaron Barchowsky, to discover the health effects of arsenic exposure.

Chemical & Engineering News featured an article on research by Yon Rojanasakul and Travis Knuckles that we discussed a few weeks ago, which showed health effects from dust generated from mountaintop mining operations.
