URI researcher: ‘Emerging contaminants of concern’ detected throughout Narragansett Bay watershed

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.
