Carried out ecological and hygienic assessment of pollution of surface and groundwater of mining areas in the Republic of Bashkortostan. Revealed exceeding standards for fishery water bodies and drinking and cultural and community water use, which indicates the potential danger of surface water for the health of the region's population. The greatest relative contribution to the overall pollution of surface water bodies are making manganese (33,0–66,6 %), iron (9,1–15,6 %), calcium (6,5–11,7 %), lead (5,8– 7,2 %). The quality of water used for drinking purposes from decentralized water sources (boreholes, wells, springs), do not always correspond to the hygienic and sanitary-epidemiological requirements. In this case, the highest priority performance of drinking water contamination are increased stiffness, high content of iron, calcium, nitrate, presence cadmium, and hexavalent chromium.

Background: Within the framework of cholera surveillance in the Russian Federation, annual isolation of nontoxigenic V. cholerae O1 strains from water bodies is registered in the Republic of Kalmykia. This fact is the rationale for the present study and analysis of data on contamination of water bodies with V. cholerae O1 with account for some environmental and quality indicators of water bodies used for recreational purposes. Objective: To study contamination of water bodies with V. cholerae O1 as a component of cholera control surveillance in the Republic of Kalmykia. Materials and methods: We used notifications issued by Offices of the Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing (Rospotrebnadzor) in the constituent entities of the Russian Federation, passports for V. cholerae O1 strains, and information from “Cholera vibrios. Russia” database for 1991–2019. Results: In the 1970s, 1980s and 1990s, several outbreaks, sporadic and single imported cases of cholera were registered in the republic. The total of 446 strains of V. cholerae O1 El Tor were isolated during the analyzed period. The PCR analysis identified them as V. cholerae O1 ctxA–tcpA– and V. cholerae O1 ctxA– tcpA+. We observed an increasing trend in the number of isolated strains with the approximation coefficient of 0.374 against its general decrease in the country in 1991–2019. Strains were isolated annually, mainly from the Elista River, Zayachy Pond and other water bodies with poor microbiological and chemical water quality parameters. V. cholerae O1 ctxA– tcpA+ were isolated mainly at the wastewater discharge sites, which indicated their imported origin, along with V. cholerae O1 ctxA– tcpA– with InDel and PCR genotypes not previously found in this region. We consider the contamination of water bodies with V. cholerae O1 ctxA– tcpA– and V. cholerae O1 ctxA– tcpA+ as prerequisites for possible deterioration of the local epidemiological situation due to cholera importation from endemic areas. Conclusion: When analyzing the pollution of water bodies in the Republic of Kalmykia with V. cholerae O1, we established a long-term annual isolation of cholera vibrios from some water bodies in the city of Elista, including Elistinka river, Zayachy and Kolonsky ponds, notorious for poor microbiological and chemical water quality indicators. The contamination was mainly attributed to domestic wastewater discharge and poorly treated effluents of sewage treatment plants into the Elistinka river within the city boundaries, as well as watercourses from hollows. This proves the imported origin of the bacterium confirmed by isolation of V. cholerae O1 ctxA– tcpA– with InDel- and PCR-genotypes not previously found in this region.

This article presents results of studying distribution and seasonal dynamics of associative parasitosis of gastrointestinal tract of sheep. It was found that most common cases in surveyed sheep farms were recorded invasion of sheep with strongyles of gastrointestinal tract (in 100% of cases) with an average invasion intensity of 55.47% and an invasion intensity of 14.26 eggs per 1 g of feces. The predominant trichostrongylidae spp. in structure are haemonchus – 54.56%, they also pose greatest danger to sheep, since they are hematophages. Samples from 66.67% of surveyed farms revealed Eimeria spp. with an invasion intensity from 32.2% to 72% and an invasion intensity from 233.15 to 1685.32 oocysts in 1 g of feces. Strongyloides invasion was detected in 50% of surveyed farms. On average, prevalence of invasion was 18.38%. It was found that most critical period with a significantly high degree of invasion in young lambs is spring season (p<0.001), which is characterized by a high degree of extensiveness and intensity of invasion (Eimeria spp. and cryptosporidium).

Invasive diseases of horses are an urgent problem in the horse breeding industry of the Republic of Belarus, as well as in the near and far abroad countries. The main role among the parasitic pathology is occupied by helminths of the small and large intestine, as well as larvae of gasterophilus. In associative course, they are the cause of significant economic losses associated with the growth and development of sick young animals, reduced performance, endurance of animals, increased susceptibility to other diseases, and even the death of animals. Planned therapeutic and preventive measures using broad-spectrum anthelmintics is a priority measure to reduce economic damage in development of the horse breeding industry. The paper provides data on spread of parasitoses of gastrointestinal tract in horses in the Republic of Belarus during period of 2004-2020. The paper presents the species composition of horse parasites localized in the stomach, small and large intestines. Data on extensiveness and intensity of invasions of horses by parasitocenosis of digestive tract in terms of age are presented. Therapeutic efficiency of antiparasitic drugs of various pharmacological groups in mono- and polyinfestations of gastrointestinal tract of horses are studied. High extensibility of Avermectin series preparations (Avermectin paste 1 %, Rivertin 1 %) has been determined for nematodes of gastrointestinal tract of horses and gastrointestinal disease. High efficiency has been obtained from a new complex antiparasitic preparation for horses “Prazimax” in mono- and polyinfestations caused by parasites of gastrointestinal tract, including nematodes of the small and large intestines, larvae of gasterophilus and Anoplocephala perfoliata cestodes. Data on spread of associative course of parasitocenoses of the digestive tract of horses, age and seasonal dynamics will allow veterinary specialists to make timely diagnosis, conduct differential diagnostics, determine the optimal timing of diagnostic, therapeutic and preventive treatments, taking into account the specifics of parasitocenosis.

Abstract The process of integration into the European Union (EU) requires from new member states significant efforts; not only harmonizing legislation but also respecting all posed standards. Among numerous issues, wastewater purification represents a significant request. To achieve the goal of discharging good-quality water into natural water bodies as recipients, various methods have been used. The method of constructed wetland (CW) is based on wastewater purification by using wetland plants. The method of CWs shows the best results for small settlements for up to 5,000 inhabitants and can be nicely integrated within the landscape of a plain where waterbodies’ banks are overgrown by wetland plants. Such facilities have been used for decades in the territory of the EU, and only a few have been built in the Republic of Serbia. Since the Republic of Serbia is a candidate country for the EU, there is a strong intention to take action focused upon solving wastewater purification from various sources. Therefore, this paper aims to examine favourable locations for CW installations within the rural area of the South Bačka District. Geographic information system was applied for examination of the basic spatial criteria (distance from the settlement, distance from water bodies, elevation, and land use). These were presented in separate maps and finally in one joint map of favourability for establishing CWs in the vicinity of 35 villages within the District. The obtained results have fulfilled the basic spatial preconditions, but further analyses should be conducted to precisely position the location of each CW concerning land ownership criterion.

Safe Condition

Deep underground reservoirs are characterized by a stable structure with unique properties to contain and retain various production waste for a long time in a safe condition. In this context, deep underground aquifers are considered as localized underground targets designed for industrial waste disposal to prevent or reduce a maninduced load on surface water bodies, resources of which are sought-for the drinking and domestic water supply.  In the environmental legislation of the Republic of Kazakhstan, the limits for the environmental emissions are established within the maximum permissible discharges (MPD) of industrial wastewater exclusively for surface water bodies. At the same time, no define procedural conditions were determined in the legal norms for MPD limitation when injecting industrial wastewater to the underground aquifers that are also referred to the water bodies as defined.  A methodological approach to the limitation of harmful and (or) hazardous substances in industrial wastewater injected to the deep underground localized horizons is considered in the proposed review based on the existing developments of the leading oil companies in the Republic of Kazakhstan taking into account the requirements of the national environmental legislation.
