Microbiological indicators of water in the coastal areas of the Gulf of Finland

Abstract

The article is devoted to the study of the microbiological indicators of the water of the Gulf of Finland and the assessment of the safety of products extracted from there for the population. Exceeded the maximum permissible concentrations for microbiological indicators and identified the causes of the excess. For the study, water samples were taken at various points in the coastal areas of the Gulf of Finland. Samples were tested for such safety indicators as total microbial count, total and thermotolerant coliforms, as well as the content of bacteria of the genus Salmonella. The total microbial number was taken into account at different temperatures, which made it possible to further calculate the degree of self-purification of the reservoir. The obtained results were checked for compliance with the standards for each of the indicators, which made it possible to determine the degree of water safety, as well as, indirectly, the fish caught from this source for humans.
