Progress has been made towards optimizing a rapid, accurate method for extracting pesticides from soil for routine analyses. The basis of the method is the formation of a supernatant by sonication of the soil with a water-acetone mixture. After removal from the soil particles, the pesticides are extracted by passing through a disk of octyl-bonded silica sorbent.To establish the suitable extraction...
