New project searches for contaminants of emerging concern

PSI research scientist Andy James has been funded by the Environmental Protection Agency’s National Estuary Program to identify contaminants of emerging concern (CECs) in the waters of Puget Sound.

There are literally thousands of man-made chemicals known as CECs circulating in local waters, but very little is known about their impacts on wildlife. They are often found in tiny concentrations and can include residuals from pharmaceuticals and personal care products that are flushed through treated wastewater.

James’ project will extend through May 2019 and will focus on the non-targeted sampling of marine waters and shellfish, as well as selected streams in Puget Sound. James will use mass spectrometry to analyze samples with an eye toward identifying CECs that might have the potential to cause risk to aquatic organisms.

Collaborators include researchers at the University of Washington Center for Urban Waters, the Department of Ecology and the Washington Department of Fish and Wildlife.

Funding Amount: $200,000.

Project duration: Now through May 2019.

Healthy stream, healthy bugs

Many groups have been formed around the goal of saving salmon, but few people talk about a concerted effort to save microscopic creatures. Whether or not a pro-bug movement catches on, future strategies to save salmon are likely to incorporate ideas for restoring streambound creatures known as benthic invertebrates.

The Puget Sound Ecosystem Monitoring Program released its fifth annual Marine Waters Report today. The report provides an assessment of marine conditions for the year 2015 and includes updates on water quality as well as status reports for select plankton, seabirds, fish and marine mammals.

According to the report, water temperatures broke records throughout Puget Sound. The year was also the worst on record for two distinct stocks of Pacific herring. You can read the full report on the Puget Sound Partnership website.

New theory rethinks spread of PCBs and other toxics in Puget Sound

Last month, more than 1100 scientists and researchers converged on Vancouver, B.C. to attend the Salish Sea Ecosystem Conference. The biennial conference is the region’s largest gathering on the state of the ecosystem, and we sent a group of reporters to bring back some of the highlights. Over the next several months, we’ll be collecting those highlights into a new series on the Encyclopedia of Puget Sound. We kick things off today with a must-read story from Christopher Dunagan. He reports that scientists may be changing their view of how PCBs and other toxics enter the Puget Sound food web. Read the story in Salish Sea Currents.
