Abstract

In most regions of the central part of the North Caucasus, there is a persistent increase in the prevalence rate of congenital malformations of the child population and the development of other health problems. It is probable due to the fact that unlike many other regions of Russia the upper reaches of the Kuban water are contaminated by metals with a significant excess of MPCrx due to their entry from rock depths. The highest excess of manganese, copper and iron was observed. For other metals there are specific for individual waters deviations upward or downward. To date, the water in large quantities for the irrigation network is transmitted in steppe regions, feasting upon the path of additional quantities of natural contaminants, and mainly anthropogenic origin. The massive use of irrigated agriculture, the saturation of groundwater contaminants is the basis for their accumulation in the agricultural products. Thus, after drinking it is the second a local source of metals in the human body. The problem for detection of correlative relationships between pollution and human health in this case is the lack of such a target as the total MPC of pollutants in the human body, balancing entry-selection for different age, gender and other characteristics of human differences.
