Abbreviations used: nd - indicates that the analyte was not detected above the limit of detection which ranged from 2 to 30 ng/g (ppb) wet weight.

RSD - relative standard deviation is the standard deviation divided by the mean and expressed as a percent

GC/MS - gas chromatography/mass spectrophotometry

Results were determined by gas chromatography (GC)/electron capture detection (ECD)

4,4'-dibromooctofluorobiphenyl was the internal standard (surrogate standard) for all the analytes

Percent recoveries for the internal standards averaged 87%, RSD = 20%, n = 55.
