'Emerging contaminants of concern' detected throughout Narragansett Bay watershed
Date:9/21/2011

n upper Narragansett Bay, while some detergents were detected at similar levels at nearly every site.

"Many of the trends in society from early puberty changes to some diseases may be caused by chemical exposures," said Lohmann. "They trigger hormones and disrupt the normal functioning of the body. We have no resistance against them."

The chemical compounds were detected using polyethelene passive samplers, thin pieces of plastic that absorb chemicals that are dissolved in water. The volunteers placed the samplers in various rivers and coves in the Narragansett Bay watershed in the fall of 2009 and retrieved them two to three weeks later. The chemical compounds were then extracted from the samplers in a lab at the URI Graduate School of Oceanography.

"We couldn't have done this work without the volunteers," Lohmann said. "They have helped us find potential sources for some of these chemicals."

"Unfortunately, no matter how you choose your lifestyle, you can't avoid exposure to these compounds," he added. "You just can't escape."
