Abstract
an elegant and efficient microcolumn cleanup method is described for the analysis of pesticide residues present in some environmental samples. Crude extracts of conifer foliage, forest soil and fortified with four commonly used forestry pesticides, fenitrothion, aminocarb, carbaryl and mexacarbate. After necessary microcolumn cleanup using different solvent systems, the samples were analyzed by N-P specific gas chromatography (GC). The analytes gave very clean chromatograms. The recoveries ranged from 79% to 100% and the eluting times varied from 1o to 30 min. The method diescribes is simple, fast, economical and not laborious. A total of 12 samples could be cleaned simultaneously by one individual. the time involved in the cleanup and the use of expensive organic solvents are minimized considerably.
