SAN FRANCISCO — 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.
Dominic Gregorio, a senior environmental scientist with the State Water Resources Control Board will probably put together a report in few years!

Regulators are concerned about an array of chemicals and pharmaceuticals – synthetic estrogen used in birth control pills, anti-bacterial agents in hand sanitizers and a flame retardant used on computers, furniture and cars – that can accumulate in the tissue of animals and people. Recent studies found levels of PBDEs, or polybrominated diphenyl ethers, a flame retardant used in the manufacture of a wide range of consumer products, in waters off of every U.S. coast.
