A modification of Miles' method for determining azinphos-methyl residues in crops

Abstract

Meagher's, Bluman's and Miles' methods for determining azinphosmethyl residues were assessed on a range of crops. Some shortcomings were encountered with the three methods and, to overcome them, a modification of Miles' method, involving the use of acetone extraction, is proposed and evaluated. The cleaned-up extract can also be used in an established chromatographic identification procedure.
