[Evaluation of the efficiency of measures to reduce the influence of risk factors on human health].

65% of the region's population is covered by the complex monitoring and control of environmental factors. Chemical contamination of drinking water with iron, manganese, boron, or nitrates makes a 60% contribution to anthropogenic load. Implementation of the measures of a special urban program could reduce the proportion of the drinking water, which did not meet the hygienic standards by sanitary chemical indicators, in Voronezh from 10.2% in 1999 to 8.5% in 2008 and halve the concentration of manganese and iron.
