Introduction. Among the new pesticides relevant one is application of benthiavalicarb-isopropyl pertaining to the carbamates class.
Hygienic standards and regulations are not approved for this substance in Ukraine.
The aim of studies was to substantiate the maximum allowable concentration (MAC) of new carbamates class fungicide benthiavalicarb-isopropyl in the water.
Materials and methods. Physical and chemical, organoleptic, photometric, chromatographic, and statistical analysis methods were used.
Results. Threshold concentrations of benthiavalicarb-isopropyl were established according to organoleptic properties of water at the level of 0.06 mg/dm3 (limiting criteria – odor at 20°Ñ), to gen-eral-sanitary index – 0.06 mg/dm3 (limiting criteria – influence on biochemical oxygen intake and nitrification processes) and to sanitary-toxicological index of hazard – 0.005 mg/dm3.
Conclusions. The maximum allowable concentrations (MAC) of benthiavalicarb-isopropyl in water on the level – 0,005 mg/dm3 were scientifically substantiated (limiting criteria of hazard – sani-tary-toxicological).
