Malathion in the blood was determined by gas liquid chromatography with a flame thermionic detector on 1.0 m glass column packed with 10% DC-200 at 225°C. The blood was haemolyzed by the addition of 9 parts of water, subjected to modified Extrelut[○!R] column and malathion was eluted from the column with n-hexane. Determination was carried out successfully by the internal standard method using cyanophenphos. The calibration curve of malathion in ethyl acetate solution (0.5-4.0 μg/ml) showed a straight line. The recovery of malathion added to the blood (4.0 μg/ml) was 100.32±2.07%. Malathion in the blood of a suicide was identified by gas liquid chromatography-chemical ionization mass spectrometry and the content was 1.03 μg/ml.
