摘要
Liver and muscle tissues from Atlhntic salmon (Salmo salar) were analyzed for residues of dichlorvos after treatment against salmon lice infestations at water temperatures of 4 and 12 °C. Dichlorvos was extracted from tissue samples with cyclohexane and acetone, cleaned by gel permeation chromatography, and determined by gas chromatography (glass capillary column and alkali flame nitrogen-phosphorus specific detector). Though at a water temperature of 4 °C residues were detectable in muscular tissue for up to 3 days after treatment, at 12 °C they could only be detected in samples taken directly after treatment. In liver tissue, residues were detectable for up to 3 days after treatment at 4 °C, while at 12 °C traces of dichlorvos were evident in some samples for up to 6 days after treatment. © 1990, American Chemical Society.
