Systematic determination method for various kinds of pesticides (organochlorine, organophosphorus, carbamate, acid amide, dinitro aniline) was described. The pesticides were simultaneously extracted from sample with acetone and acetone-water (7 : 3) mixture, diluted with 10% NaCl solution, and reextracted with dichloromethane-hexane (1 : 4) mixture. The organic layer was concentrated, purified by partition between acetonitrile and hexane, fractionated by silica gel or active charcoal column chromatography, and then determined by gas chromatography with electron capture or flame thermionic detection system. Recoveries of the 8 pesticides (quintozene, chlorothalonil, disulfoton, o, o-Diisopropyl S-benzyl phosphorothioate, 3-(sec-Butyl) phenyl N-methylcarbamate, propoxur, alachlor and trifluraline) added to orange and wheat were within the range of 57.0-71.8% by the proposed method.
