Abstract

The measurement of xenobiotics (polycyclic aromatic hydrocarbons (PAHs) group) in agricultural objects: soil, water, plant products was developed and tested by the high performance liquid chromatography method in this work. Our investigation was carried out by using laboratory samples taken from the research farm "Snitynka". Optimal modes of high-performance liquid chromatography method with a fluorescent detector (HPLC/FLD) were established for xenobiotics measurement: benzo(a)anthracene, benzo(a)pyrene, benzo(e)pyrene, benzo(b)fluorine, chrysene and their mixtures. Metrological characteristics of PAHs measuring were established: the limit of quantitative analysis (LOQ = 1.0 μg/kg), the limit of detection (LOD = 0.25 μg/kg), measuring range 1.0 - 10.0 μg/kg, the total measurement error (%) for each xenobiotics content average did not exceed 20%. The approbation of the methodology was performed in series of 50 model samples in the concentration range of each xenobiotics from 1.0±0.1 μg/kg to 10.0±0.1 μg/kg and in series of 50 natural samples. It is established that the developed method allows to unify laboratory control of PAHs and improves the process of monitoring analysis of xenobiotics.
