Scientists begin testing mussels for pollutants

California scientists hope studying 180 black mussels pried from algae-covered rocks in San Francisco Bay will provide clues into how many drugs and chemicals are polluting waters across the nation.
Mussels filter water and store contaminants in their tissue, providing a record of pollution in the environment. The creatures are being culled from 80 sites in California as part of a pilot study by the National Oceanic and Atmospheric Administration.
Regulators are concerned about an array of chemicals and pharmaceuticals that can accumulate in the tissue of animals and people. Recent studies found levels of a flame retardant waters off of every U.S. coast.
The data from tests on the mussels will help guide the study of contaminants in other states.
