Brief Method Summary

Chlorinated hydrocarbons are quantitatively determined by gas chromatography with an electron capture detector (ECD). The ECD is very sensitive and allows for detection of the chlorinated hydrocarbons at trace concentrations (ppb) in marine animal tissue. Silica gel/alumina cleanup with activated copper was used to remove interfering materials from the sample prior to analysis.

Scope and Application

This method quantitatively determines chlorinated pesticides and PCBs in animal tissue using GC/ECD.

Applicable Concentration Range

5 to 200 ng/g

Interferences

Method interferences may be caused by contaminants in solvents, reagents, glassware, and other sample processing hardware, and lead to false positives during instrumental analysis. All materials used in this method are routinely demonstrated to be free from interferences by processing procedural blanks identical to samples (one blank per 20 samples or each batch whichever is more frequent). Matrix interferences result from co-extraction of compounds other than the analytes of interest. Elemental sulfur and naturally occurring lipids can cause interferences in the analysis of tissue extracts.

Quality Control Requirements

The quality assurance / quality control requirements were as follows: Initial calibration and continuing calibration checks. Method blank analysis. Surrogate compound analysis. Matrix spike analysis. Reference sample analysis.

Sample Handling

Collect samples in a glass container and store in the dark at or below -20 deg. C. Store extracts in the dark at 4 deg. C.

Maximum Holding Time

6 months (frozen)

Relative Cost

$201 to $400
