Abstract
A method is described for analyzing polybrominated diphenyl ethers (PBDEs) in fish tissue using gas chromatography with atomic emission detection (GC/AED) and quantitation by compound independent calibration (CIC). The method has the advantage of an element-selective response, including selectivity between bromine and chlorine. An analysis of fish tissue samples from selected locations in Washington State showed total PBDE concentrations ranged from 1.4 μg/kg (wet weight) in rainbow trout from a remote spring-fed stream to 1,250 μg/kg in mountain whitefish from the urbanized Spokane River. Tetra and penta isomers were the major compounds present. There appear to be substantial between-species differences in the ability of fish to metabolize PBDEs.
