Flame retardant chemicals are building up in some of Washington’s rivers and lakes, according to a state Department of Ecology (Ecology) study released on Aug. 31.

Ecology collected fish from 20 major rivers and lakes throughout Washington during 2005. Three-to-four fish species were typically analyzed for each waterbody. The goal of the survey was to establish existing levels of PBDEs (polybrominated diphenyl ethers) that could be used in the future to evaluate the effectiveness of the state’s efforts to reduce PBDEs in the environment.
