Specifically, they used mussels as a barometer of pollution in the waters off Seattle, and discovered that oxycodone is now present enough in the marine environment there for shellfish to test positive.
Since mussels are “filter feeders,” they absorb contaminants from their environment into their tissues in a concentrated way. Scientists used cages to transplant clean mussels from an aquaculture source on Whidbey Island to 18 urbanized locations around Puget Sound. Several months later, they pulled those previously uncontaminated mussels back out of the urban waters and, together with the Puget Sound Institute, tested them again.
In three of the 18 locations, the mussels then tested positive for trace amounts of oxycodone. How, you ask? […]
