Introduction. Hygienic regulation of modern pesticides Kelvin Plus and Plenum 50 WG includes studying work conditions in their application for protection of oil crops and risk assessment of the combined (inhalation and dermal) effect of active substances (a. s.) of both preparations on workers.

Purpose of the study. Risk assessment of isolated and combined effects of dicamba, diflufenzopyr, nicosulfuron and pymetrozine on workers, engaged in the use of Kelvin Plus and Plenum 50 WG.

Materials and methods. Field studies have been conducted; samples of the working zone air were taken, there have been taken washings from open skin areas and from under the protective clothing, from stripes of the protective clothing; the content of residues of pesticide active substance in samples are defined; exposure and permissible inhalation and dermal doses of active substances and coefficients and hazard indexes have been calculated.

Results and discussion. It is stated that Boom spraying of Kelvin Plus and Plenum 50 WG with maximum consumption rates (0,40 and 0,25 kg/ha) is not accompanied by the dangerous contamination of the working zone air and the skin of workers. Hazard indexes of the combined harmful effect of a. s. of both preparations and the combined effect of three a. s. of Kelvin Plus are below 1,0; work conditions of a setter and a tractor operator are permissible. The inhalation intake of pesticides plays the leading role in the formation of occupational risk. The hazard coefficient of the inhalation intake for tractor operators is about 2,0–4,3 times higher than for setters. The safety coefficient for clothing is 21,2–41,8.

Conclusion. The use of both preparations on oil crops sowings does not cause any harm to workers when using traditional technical means of plant protection in the case of keeping to the established agrotechnical and hygienic regulations.

Key words: herbicide, insecticide, a hazard coefficient, hazard index, occupational risk
