| description | Objective of research: The purpose of the study is to carry out ecological and sanitary-parasitological monitoring of soils, waste water and sewage for the presence of eggs of geohelminths (Toxocara SPP) in Nizhnevartovsk, Khanty-Mansiysk Autonomous Okrug - Ugra, in 2013 to 2015. The materials and methods. The collection of material and dynamic observations were carried out in the period from 2013 to 2015 on the territory of Nizhnevartovsk. The research was conducted in parasitological lab of the Center of Hygiene and Epidemiology in Khanty-Mansiysk Autonomous Okrug Ugra in Nizhnevartovsk and Nizhnevartovsk district, in the cities Megion and Raduzhny. Dog feces, soil samples, wastewater and sewage served as our research material. We used the sanitary-parasitological, coproovoscopic and statistical methods of research. The results and discussion. Thus, the results obtained in this study give reason to believe that the population of dogs in the city is a constant source of abundant contamination of the environment by helminth eggs, first of all, by Toxocara eggs, representing a threat to humans. An important element in reduction of toxocariasis should be the control of dog populations through intensive trapping of stray and neglected animals, the development of rules and regulations of the density of their populations through the relevant veterinary and sanitary authorities, as well as improving sanitary requirements for maintenance of animals. Assessing soil contamination by eggs of Toxocara spp. we can conclude that in accordance with the sanitary-epidemiological rules and norms, the degree of epidemic danger of soil given in SanPiN 2.1.7.1287 - 03 «Sanitary and epidemiological requirements for soil quality», the city of Nizhnevartovsk (Khanty-Mansiysk Autonomous Okrug) can be characterized as moderately hazardous. The results obtained in the study of wastewater sewage and its precipitation showed that the treatment plant while going through all the stages of decontamination provides full dehelmintization and desinvasion (inactivation of viable helminth eggs) of wastewater and their fractions. |
