Lakes Are Loaded With Chemicals, Even Cocaine
May 20, 2013
From urban and developed to remote and isolated, lakes around Minnesota contain a wide range of chemicals, including DEET, BPA, prescription drugs and even cocaine.
The findings, which came out of the first large-scale, systematic statewide study, suggest that it might be worth taking a wider look at bodies of water around the country for chemicals that have potential consequences for both the environment and human health.
For now, it’s not clear how all of the chemicals are getting into Minnesota’s lakes or exactly what effects they might be having on animals or people.
PCBs Are Everywhere: Problem Exists in Industrial City and Rural Community
May 8, 2013
Since polychlorinated biphenyls (PCBs) are produced through industrial processes or activities, it is assumed that people living in industrial cities will have higher concentrations of these toxic chemicals in their blood than people in rural communities.
Researchers at the University of Iowa say this isn't the case. In a paper published in March in the journal Environmental Science & Technology, scientists report that mothers and children in East Chicago, Ind., and Columbus Junction, Iowa, had only subtle differences in their PCB blood levels. This analytical paper is the first to report such a comparison between two communities, between mothers and children, and including all 209 PCB compounds.
