Description
Summary:The extent of 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and 2,3,7,8-tetrachlorodibenzofuran (TCDF) contamination of 2 types of shellfish within their migratory ranges in a polluted environment was studied by collecting blue crabs (Callinectes sapidus and American lobsters (Homarus americanus) at sea and purchasing in markets. Samples of hepatopancreas and thoracic, claw, leg and tail meat were homogenized, saponified, extracted, acid-washed, cleaned-up by a series of extractions and elutions, then analysed by gas chromatography-mass spectrometry. Combined samples from blue crabs from the lower Hudson river and Raritan bay had average TCDD equivalents of 78.2 pg per g which exceeded the no-consumption guideline of 50 pg per g. There were no detectable levels in controls. Concentrations in lobsters were 44.4 and 38.5 pg TCDD equivalents per g for the lower Hudson river and Raritan bay, respectively. Most of the contaminants were in the hepatopancreas with little in the muscle. The commercial origin of some of the shellfish and the relatively high levels of detection cast doubt on the accuracy of the conclusions.
