‘Forever chemicals’ found in Chesapeake region's freshwater fish
"High levels of “forever chemicals” have been reported in freshwater fish and water from a Maryland creek, raising new questions about the extent and seriousness of these compounds’ contamination in the Chesapeake Bay watershed.
Per– and poly-fluoroalkyl substances, or PFAS, were found in the blood plasma of smallmouth bass taken in 2018 from Antietam Creek near where it flows into the Potomac River, according to Vicki Blazer, a biologist with the U.S. Geological Survey's Leetown Science Center in Kearneysville, WV.
PFAS compounds also were detected — though at lower levels — in the plasma of the popular gamefish in three other locations: the South Branch of the Potomac in West Virginia and at two sites in the Susquehanna River in Pennsylvania.
PFAS are a group of more than 4,700 chemicals that have been used for decades in a wide variety of products, including nonstick cookware, stain– and water-repellant fabrics and fire-fighting foams. They are very persistent — hence their nickname — and have been found across the United States in groundwater and surface water, in fish and other foods, as well as in people’s bodies. . ."
