Comparative Study[Relation between the processes of water self-purification and the level of microbial pollution in the southern regions of the 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.

[Contribution of petroleum-processing plants to the total level of atmospheric air pollution].
On the basis of results of field studies the means to reveal the contribution of oil extracting and processing enterprises (the main components of discharges are similar to the common prevalent impurities in the air of residential areas) into the total level of ambient air pollution has been developed. The method takes into account the relationship between average annual concentrations of oil hydrocarbons and carbon oxide.
