Water Translocation of Diazinon-C14and Parathion-S35off a Model Cranberry Bog and Subsequent Occurrence in Fish and Mussels

摘要

Transportation of diazinon-C14and parathion-S35off a model cranberry bog following a simulated frost protection flood was shown 24 hr after application of the chemicals. Fish (Fundulus heteroclitus L.) and freshwater mussels (Elliptio complanatus Solander) were exposed to these contaminated waters and analyzed periodically. The majority of the chemicals disappeared from the water after 144 hr. During this time, no labeled metabolites of diazinon were detected; however, three labeled parathion degradation products were encountered. Accumulation of both pesticides occurred in the fish and mussels, often to levels far in excess of that present in the waters. The fish appear able to metabolize these accumulated chemicals at a faster rate than the mussels.
