Chances are examined for the identification and determination of pesticides of different types and polycyclic aromatic hydrocarbons, 46 items, in water and food by means of gas chromatography with time-of-flight mass spectrometry detection. The detection limits make from 0.01 to 0.5 mg/L if the injected volume of samples is 1 μL; the analytical range is 0.02–10 mg/L. In the mode of selective ion registration and preliminary preconcentration by liquid and solid-phase extraction, the detection limits of analytes make from 2 to 100 ng/L in water and from 0.2 to 10 μg/kg for solid samples.
