Relevance. The scientific substantiation of the method selection, the development of conditions for qualitative identification and quantitative determination of Axial 050 EC, Peak 75 WG, Tilt 250 EC, Magnello 350 EC, Enzhio 247 SS, Karate Zeon 050 CC pesticides (by its simultaneous presence) used in cereal crops protection system was given in the article, as well as preparation conditions for the analysis of water and air samples were described, which will allow to control the established hygienic standards and minimize pesticide negative impact on population health and the environment.
Objective of the research is to develop methods for the analytical determination of 9 active substances of 7 pesticide preparations applied in the wheat and barley protection system with its simultaneous presence in water and air.
Materials and methods. Chromatographic analysis was performed by Shimazu (Japan) liquid chromatograph. Chromatograph control, recording, analysis and storage of chromatographic data were performed using S/w LC solution software. The package of IBM SPSS StatisticsBase v.22 and MS Exel statistical programs was used for statistical processing of results.
Results. The developed optimal conditions of sample preparation and chromatographic determination in the combined presence of 9 different chemical classes pesticides used in the cereal crops protection system will allow to control their content with the limit of quantitative determination of each compound 0,001 mg/dm3 in the water sample, and 0,05 mg/m3 in the air, thus allowing control the established hygienic standards of these compounds in the water and in the working zone air.
Conclusions. The conditions for simultaneous determination of prosulfuron and pinoxaden herbicides, thiamethoxam and lambda-cyhalothrin insecticides, fludioxonil, sedaxane, tebuconazole, propiconazole, diphenoconazole fungicides in its combined presence in the water or air samples by high-efficiency liquid chromatography method were elaborated allowing the efficiency of analysis to be increased and its total price to be reduced.
