摘要

Dioxathion residues in milk (expressed as the sum of the cis and trans isomers) have been determined by gas liquid chromatography using the N-P thermionic detector. It was found that dioxathion residues of 0.06 to 2.29 ppm (fat basis) are present in milk and are associated with tick control procedures of spraying cows with 0.05% w/v dioxathion (Delnav) twice weekly. Average concentrations from bulked milk were 0.96 ppm after 10 hours, 0.54 ppm after 34 hours and 0.4 ppm after 58 hours following spraying. The levels of residues in the milk differed greatly in different animals.
