Sanitary condition of soil in the territory of Astrakhan state technical university and nearby territories of higher educational institutions

Objective. The authors of this article studied and analyzed the sanitary condition of the soil in the territory of Astrakhan State Technical University and the nearby territories of higher educational institutions.

Materials and methods. The study was carried out in May – June 2019 on the basis of the laboratory of the Department of Infectious Diseases and Epidemiology of Astrakhan State Medical University and the laboratory of the Department of Applied Biology and Microbiology of Astrakhan State Technical University. Thirty soil samples were taken from these territories.

The studies of soil samples for parasitological indicators were performed according to the guidelines "Control Methods. Biological and Microbiological Factors. Methods of Sanitary and Parasitological Research", for microbiological indicators – "Methods of Soil Microbiological Control".

Results. The following results were obtained: the sanitary-parasitological condition of the soil in parks near higher educational institutions in Astrakhan remains very tense as evidenced by positive findings of geohelminthoses; when assessing the degree of epidemic hazard of soil, there were identified nematode eggs and adult worm Strongyloids, that corresponds to the indicators of moderately hazard soil; the presence of live strongylid larvae in the studied samples indicates contamination of the soil with feces of infested animals, and the presence of Ascaris eggs indicates contamination of the soil with sewage or feces of infested children walking and resting in these territories; the total microbial number on average gave indicators for evaluating the selected soil samples as a slightly polluted soil.

Conclusions. The sanitary and parasitological state of soil in parks of Astrakhan higher educational institutions remains rather tense as evidenced by positive findings of geohelminthoses.
