[Hygienic aspects of Nizhnekamsk and Kuibyshev water reservoir protection under conditions of reclamation of irrigated deposits of non-ore building materials]. / Gigienicheskie aspekty okhrany Nizhnekamskogo i Kuibyshevskogo vodokhranilishch v usloviiakh osvoeniia obvodnennykh mestorozhdenii nerudnykh stroitel'nykh materialov.

Effects of sand and gravel extraction on water quality of two reservoirs were assessed. Water quality was found to depend on flow velocity. Hygienic requirements to safe water use by population in places of such work were substantiated.

[Complex sanitary-microbiological criteria of evaluating the quality of water in increasing anthropogenic load]. / Kompleksnye sanitarno-mikrobiologicheskie kriterii otsenki kachestva vodnykh ob''ektov v usloviiakh vozrastaiushchei antropogennoi nagruzki.

It has been established with the help of sanitary-hygienic, microbiological and statistical methods, that the increasing ++anthropogenic stress on water reservoirs induce quantitative and qualitative changes of water biocenosis under the conditions of intensive use of water reservoirs for economic purposes. It can produce unfavourable health effects on the population, as well as on the equilibrium of the local ecological microsystems. The necessity has been substantiated of the use of complex sanitary-microbiological criteria of the assessment of the quality of water objects to provide their epidemic safety, to preserve and rehabilitate the processes of ++self-purification of water under the conditions of technogenic exposures.

[Relation between the processes of water self-purification and the level of microbial pollution in the southern regions of the RSFSR]. / Zavisimost' protsessov samoochishcheniia ot urovnia mikrobnogo zagriazneniia vody v usloviiakh iuzhnoi zony RSFSR.

It has been found out as result of complex sanitary-hygienic, microbiological and statistical studies, that the intensity of processes of self-purification of the water in water objects form potentially pathogenic microflora is reduced under the im fluence of the increasing anthropogenic stress on the water bodies in the Southern area which can produce unfavourable human health effects. The necessity that a complex of sanitary-microbiological indicators of water quality should be used to provide its epidemic safety has been revealed, and also a criterion of the assessment of the process of self-purification of the water in water bodies according to the acute intestinal infections morbidity of the population.

[Evaluation of the risk of exposure to unfavorable environmental based on the results of sanitary, microbiological and clinical studies]. / Otsenka riska vozdeistviia neblagopriiatnykh faktorov okruzhaiushcheisredy po rezul'tatam sanitarno-mikrobiologicheskikh i klinicheskikh issledovanii.

It has been established as result of studies with the use of complex sanitary-hygienic, microbiological, clinical and statistical methods, that the increasing antropogenic stress causes changes in microbiocenosis of water objects of the environment and of blood serum, which may produce unfavourable human health effects. The necessity to use integral complex indexes of the state of man and water medium for the assessment of the degree of risk of ++eco-technogenic effects has been found out.
