摘要：

Traces of fourteen organophosphorus pesticides in environmental samples such as river water, sediment and fish were determined by capillary GC-MS with selected-ion monitoring. The pesticides could be determined within the range 0.02-0.75 ng/ml in water with relative standard deviations (R.S.D.s) of 1.0-31.4% (except for MPP, 1.0-10.9%). The detection limits of the pesticides were 0.013-0.120 ng/ml in water. Their recoveries from river water, sea water, sediment and fish samples were 101-132%, 103-145%, 93-166% (except for isoxathion) and 67-101% (except for isoxathion and phosmet), with R.S.D.s of 1.1-8.0%, 0.9-8.2%, 6.2-28.5% and 4.2-10.8%, respectively.
