Taking into account the fact that current calculation methods for substantiation of standards in the water of water reservoirs valid in Ukraine are outdated the aim of our research was to scientifically substantiate the possibility to make and to use prediction models of pesticides design standard in the water of ponds used for household and drinking water supply. Array of experimentally substantiated and approved to use in Ukraine maximum allowable concentrations (MAC) of organic pesticides active ingredients in the water was analyzed (n = 201). Analysis of dependence between MAC value of pesticides in the water and its physical and chemical properties, indices of ecotoxicological hazard and persistency in the water was carried out using correlation and regression analysis methods.

It it confirmed by the value of de Ritis coefficient, which is statistically the same as control. Morphological studies also confirm these data--degenerative changes of hepatocytes, reactive changes of the stroma and vascular responses were detected.

Risk for population health due to consumption of raw agricultural crops with triazole residues is acceptable on hazard index, point of departure index and cumulative risk index, exceeds allowable level on criterion "total margin of exposure".

However, interns, Masters, practitioners are still in great need of modern educational literature/training aids. There has not yet been developed a general concept of structure of sanitary epidemiological service of Ukraine, forms and methods of its work under present-day conditions.
