RESUMO
The hygienic analysis of centralized and decentralized water supply in rural population in Irkutsk region was performed. About 403 thousand of the upstaters use water wells, voids and springs. In drinking water there were detected significant concentrations of iron, nitrates, manganese. On the base of the application of risk assessment methodology there was calculated noncarcinogenic risk for adults (HI = 1.2-1.3) and children (HI = 1.1-2.9). Carcinogenic risk for water from groundwater sources supply is 1.56 · 10(-5)-2.1 · 10(-4) for 22.2 thousand of upstaters. There were determined priority carcinogenic ingredients: arsenic (contribution is 56.3-100%) and hexad chromium (contribution is 29.9-35.8%).

AIM: Determine the level of antibodies against socially significant types/serotypes of influenza virus in sera of individuals residing in various regions of Russia. MATERIALS AND METHODS: 1525 samples of blood sera collected in August-December 2013 in 8 regions of Russian Federation were studied in hemagglutination inhibition reaction (HAI) with antigens obtained from A/California/07/09, (H1N1)pdm09, A/Victoria/361/2011(H3N2), B/Brisbane/60/2008 (Victoria line), B/Massachusetts/2/2012 (Yamagata line), A/Commongull/Chany/2006 (H5N1), A/Anhui/01/2013 (H7N9) influenza virus strains. RESULTS: None of the blood sera samples had significant HAI titers against A/H5 and A/H7 antigens. Of all the 1525 samples, 788 (52%) were positive with A(H1N1)pdm09 antigen; 734 (48%) reacted with A(H3N2) antigen; 1010 (66%) samples were positive with B/Victoria antigen and 602 (39%) samples were positive with B/Yamagata antigen. CONCLUSION: Healthcare institutions should pay attention to the correction of population immunity profile in regions for the reduction of social-economic losses from seasonal influenza epidemics.

Soil contamination with heavy metals, arsenic, and their impact on human health continues to be one of the most pressing problems. The results of studies performed in various industrial centers of the Irkutsk region are presented. Toxic substances are found to be accumulated in soils and biosubstrates of the children population.
