COMPARATIVE HYGIENIC ASSESSMENT OF WORKING CONDITIONS AND OCCUPATIONAL RISK IN THE APPLICATION OF PESTICIDES (ON THE EXAMPLE OF FUNGICIDE AMISTAR EXTRA 280, SC) USING DIFFERENT TYPES OF SPRAYERS.
OBJECTIVE
The aim: Was a comparative hygienic assessment of working conditions and occupational risk in the application of fungicide Amistar Extra 280, SC using slotted and injector sprayers.


PATIENTS AND METHODS
Materials and methods: Sprayers Super Poly 110-04 (variant №1) and Guardian Air GA110-04 (variant № 2), and certified equipment were used. The occupational risk was assessed in accordance with the methodological recommendations proposed by the L.I. Medvedia Scientific Center for Preventive Toxicology, Food and Chemical Safety specialists.


RESULTS
Results: When using the slotted sprayer Super Poly 110-04 in the air of the working zone of the tractor driver the content of azoxystrobin was 0.0015 ± 0.0001 mg/m3, cyproconazole - 0.085 ± 0.002 mg/m3, at a distance of 10 m from the edge of the field on the leeward side - 0.003 ± 0.001 and 0.11 ± 0.02 mg/m3, respectively. Visual analysis of water-sensitive cards after using slotted sprayers showed the presence of single drops of pesticide working solution in the wear zone. When applying the pesticide using a Guardian Air GA110-04 injector sprayer in the air of the working zone of the tractor driver, areas of possible wear (10 and 100 m), theconcentration of the active substances of Amistar Extra 280, SC formulation was below the limit of quantification of the method. When assessing the complex risk for tractor drivers, a statistically significant difference was found for azoxystrobin (p = 0.002) and cyproconazole (p = 0.001) when using a slotted sprayer Super Poly 110-04 and injector Guardian Air GA110-04.


CONCLUSION
Conclusions: Values of the combined complex risk of application of the Amistar Extra 280, SC formulation for tractor drivers of variant №2 application were significantly lower than those for tractor drivers of variant №1.
