RESUMO
The article highlights the methodical features of hygienic regulation of pesticide preparation in water bodies, concretizes and supplements (specified) number of positions of the acting current methodical document on hygienic evaluation of new pesticides. From the position of the comprehensive hygienic standardization there are marked principles of the study of MPC for pesticides in water bodies, there is substantiated the expediency of expanding the arsenal of methods for determination of threshold concentrations of pesticides on the impact on organoleptic properties of water and sanitary regime of reservoirs, shows the role and importance of hydrolysis processes of active ingredients ofpesticides in water, which should be considered in the assessment of the impact of drugs on the processes of self-purification of water bodies.

The paper gives the recent results of researches made at the F.F. Erisman Federal Hygiene Research Center on water-supply hygiene. It presents a functional model of comprehensive assessment of the factors determining the sanitary reliability of drinking water supply, shows the specific features of formation of conditions for water consumption in a number of regions of the Russian Federation and the risk of a water factor to human health, and substantiates the mechanism of water quality control and management at the regional level.

The research has shown that in calculation of the permissible load of a water body all compounds should be taken into account whatever their harmful limit indicator. Total loading coefficient at a level below I in all cases does not guarantee a negative influence on auto-purification process.
