of polar pesticides in water, vegetables and fruits by HPLC method
for the determination of 25 combined pesticides operating substances
(neonicotinoids, imidazole derivatives, urea derivatives, sim-triazines,
triazoles, carbamates, phosphororganic compounds, piretroids) in water,
vegetables and fruits have been developed. The range of concentrations is
0,005–10 mg/l (mg/kg) by HPLC with diode matrix detection in 220 nm. The
determination of pesticides in water has been carried out devoid of the sample
preparation and concentrating. Sample preparation in analysis of vegetables and
fruits (pesticides extraction and extract purification) was held on QuEChERS
method. The duration of the analysis is 0,5–1,0 hour, the relative standard
deviation of results does not exceed 0,05.
Key words: HPLC, combined pesticides, QuEChERS method, surface and ground
water, vegetables, fruits.
