It's all a bit of harmless fun but the fish themselves may not be. Tests have found that Seattle-area salmon are real druggies.
The everyday chemicals that humans ingest to relieve pain, fight depression and diabetes, or treat infection are winding up in the tissue of fish in Washington's Puget Sound.
A study in the journal Environmental Pollution detected unusually high levels of drugs like Advil, Benadryl, Prozac, and even birth control pills, in the tissue of salmon.
The culprit, according to the study, is human waste.
"About 45 of the 150 chemicals we examined were found in the fish," said James Meador, the lead author of the study and an aquatic toxicologist working with the National Oceanic and Atmospheric Administration. "Some of them were at high concentrations. That's the kind of information that raises eyebrows.
"Over 4,000 pharmaceuticals are currently in use or in development in the United States. Many of them are finding their way into rivers, streams, and lakes, raising concerns about how exposure could impact wildlife, or even humans who consume fish."
There are new technologies that can strip this sort of chemical contamination in the process of treating waste water but they're expensive.
