Introduction. Inadequate water is the second risk factor for the development of diseases after poverty. Therefore, one of the most important tasks in the sphere of creating the sanitary and epidemiological welfare of the population of the Russian Federation is to provide it with benign drinking water, safe in epidemiological terms and harmless in chemical composition. The purpose of this work. Conducting a hygienic assessment of the quality of drinking water for the content of this trace element at the regional level is very relevant as fluorine is important for human health, and the main way of its entry into the body is water. Material and methods. The paper presents data of own research for 2018. During this period, there were studied about 150 water samples of centralized water supply in the Vladimir region, most of which were selected in the largest settlements. The content of fluoride ions in water was determined by the method of capillary electrophoresis (HDPE F 14.1: 2: 4.157-99). As a result of the study, the Vladimir region was found to be characterized by a significant differentiation (from 0.05 mg/l to 2.75 mg/l) in the content of fluoride ions in the centralized supply water. A map was constructed for ranking the regions of the region for the content of fluoride ions in the centralized supply water. Discussions. In eight districts of the region, the fluorine content in water is much lower than the optimal values; in five regions, an exceeding the maximum permissible concentrations was detected; and only in three regions the average values are close to optimal. The different content of fluorine in water in the districts of the region is due to the natural factor of the given geographic zone. Conclusion. Providing the population of the region with benign drinking water requires a set of various measures with the development and implementation of programs to improve the water supply of populated areas. At the forefront is the individual prevention of tooth decay and fluorosis, in which an important role is played by health education, advertising of preventive drugs that have been praised by specialists.

Over a half (about 54 %) of all types of anthropogenic pollution belongs to transport. Soils at roadside areas experience active pollution with heavy metals, which are the most hazardous contaminants penetrating into the soil with the exhaust gases due to the increased traffic intensity of vehicles. Hygienic assessment of heavy metals content in the roadside area soils of the Federal highway “R-22” with a total length of 798 km has been carried out in this research. The results based on soil sampling at 11 points along the entire length of the highway at the distance of 20 and 50 m from the roadbed have been assessed. Soil sampling was done in compliance with the State Standard of GOST 17.4.4.02-2017 by the envelope method from the soil horizon at the depth of 0-20 cm. HM content in soil samples was determined by the X-ray fluorescence method applying spectrometer “Spectroscan MAX-G” in compliance with the Environmental State Standards PND F 16.1.42-04. The greatest HM content was detected in the roadside area located on the black soils of spodzol, typical, southern, dark chestnut and chestnut saline soils. It testifies of the considerable soil contamination by the passing vehicles and of a real ecological harm to public health and environment. In order to reveal harmful contaminants for the population living at the roadside areas, it is recommended to organize sanitary and hygienic monitoring of soil, surface and groundwater of the roadside areas which are subject to constant HM exposure and accumulation exceeding maximum permissible concentrations (MPC) and approximate permissible amounts (APA) set by sanitary and hygienic standards.

The paper presents an analysis of official statistics of the “Center for Hygiene and Epidemiology in the Vladimir Region” on parasitic diseases of the population of the region in 2000-2016. Analysis of the statistical material showed the following groups of parasitic diseases to be registered in the territory of the region, depending on the systematic belonging of the pathogen: protozoosis, helminthiases, acariases, and insectoses. The greatest morbidity in the region among parasitic diseases is in enterobiosis and pediculosis, the main proportion of which falls on children. The conducted ranking of the territory with the subsequent construction of maps for each nosology made it possible to identify the area’s most unfavorable both for the individual.

The population of the industrialized centers is constantly affected by the complex of technogenic factors of environmental pollution. The leading technogenic factor is known to impact negatively the population health is air pollution. Technogenic air pollution in cities is caused by the emissions of contaminants both as a result of motor transportation and industrial enterprises. This impact is one of the main reasons for the public health deterioration. Glass production is among such sources. Air pollution with toxic substances causes soil pollution, which ecological and sanitary condition can serve as a marker of environmental pollution rate. The study objective was the ecological and hygienic environment assessment of the Gorokhovets town in the Vladimir region, where modern glass empties production is functioning. Statistics of the regional official services in Gorokhovets district of the Vladimir region, as well as data from our own research have been applied for the research. Heavy metals in soil have been detected by x-ray fluorescence method applying spectrometer “Spectroscan MAX-G”. Anions content in soils was determined using water extracts from soil samples by capillary electrophoresis applying device “Kapel-104”. Results. The statistics published by the official regional state services on the gross amount of air pollutants emissions have been analyzed. Data on the heavy metals (HM) and anions content in various parts of Gorokhovets have been obtained. Conclusion. The ecologic-hygienic assessment of environment allowed to reveal that vehicles make the largest contribution to the air pollution in Gorohovets area in recent years. The main stationary air pollution source n is the glass works “Rusdzham” as first of all nitrogen oxides are its by-products.
