NOAA-NWFSC Tech Memo-3: Intraorgan Distribution of Chemical Contaminants In Harbor Porpoises

Chlorinated Hydrocarbon Analyses for the Harbor Porpoise Contaminant Distribution Study
Explanatory Notes for Tables A1-A14

Abbreviations used:

nd - indicates that the analyte was not detected above the limit of detection which ranged from < 0.1 to < 2 ng/g (ppb) wet weight.

RSD - relative standard deviation - the standard deviation divided by the mean and expressed as a percent.
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 (surrogate standards) analyzed with the subsamples and the quality control samples averaged 91%, RSD = 8%, n=52.

Identification of analytes was confirmed for lab sample 59-370 by GC/mass spectrophotometry (MS); the identification applies to all other samples (blubber and liver).

Mean values given for samples are calculated using those samples in which the designated compounds were detected. The means of the concentrations of duplicate samples were calculated first and that value was used in the calculations of the mean and RSD.
