SUMMÀRY:
Development and scientific substantiation of pesticides safe content in water used for domestic and drinking purposes are the key role of preventive medicine among other modern urgent tasks.
The aim of our studies was to carry out experimental research to substantiate the maximum allowable concentration (MAC) of dodine in water of water reservoirs.
Organoleptic, physical-chemical, photometric, microbiological and mathematical methods of water quality evaluation were used to substantiate dodine toxicological parameters and safety criteria for water of water reservoirs.
Threshold concentrations of dodine by organoleptic index were established at 0.03 mg/dm3 (limiting criterion – smell at 20°C); by general-sanitary index – 0.003 mg/dm3 (limiting criteria – bacteriostatic effects on the aquatic microbial flora and impact on the process of organic nitrogen-containing substances mineralization); by sanitary and toxicological index – 0.2 mg/dm3.
Maximum allowable concentration of dodine in water of water sources was substantiated at the level of 0.003 mg/dm3 taking into account general sanitary limiting criterion of hazard.
