Background. Implementation of new pesticide preparations in agriculture, which are produced in many countries of the world and have similar acting ingredients or a wide range of application, requires a comprehensive check of hygienic regulations in their application, adopted in Ukraine, i.e. their application should not be dangerous for workers.

Purpose of the work. To investigate the quality of the work environment, basing on the results of chemical-analytical studies in state trials of new pesticide preparations on cereal and oil cultures.

Methods, analytical equipment, materials. Methods of gas liquid and high effective liquid chromatography were used with the gas chromatograph "Kristallux 4000 and 4000M" (Russia) and the computer program "Total Turbochrom"; analytical standard samples of pesticides; мethods of statistical analysis.

Results. 19 active ingredients of 20 examined preparations in the working zone air have been defined in the process of preparation of working solutions and in the operator’s cabin, when applied on cereal crops and corns: in 1 year in the air over the treated area and in the soil; in washes from the skin of hands and face and on patches on the working cloth after ceasing the work. A degree of the probable risk for worker’s health did not exceed the permissible level. The reentry period for workers to appear at the treated area has been defined.

Conclusion. The content of pesticides in the working zone air did not exceed hygienic standards in case of keeping to technological regulations. The vapor constituent in the air pollution was not significant, excluding pesticides which could be volatile in combination with aerosols, due to their high volatility (cyproconazole, S-metolachlor). The contamination of skin on hands, face and working cloth can be connected not only with contamination of the air by liquid-drop and dust aerosols but the equipment as well. The use of earlier established hygienic regulations for the control of safety in pesticide application has been proved.

Key words: new pesticide preparations, chemical-analytical studies, pollution of the work environment (air, spoil, hands surface, face, working cloth), safe application
