ASSESSMENT OF HARMFUL EFFECT OF ENVIRONMENTAL POLLUTION ON HUMAN HEALTH IN NORTH OSSETIA

A.D. Badov

Purpose. The article deals with the degree of correlation between the pollution degree and the level of children and adult morbidity of the population in the Republic of North Ossetia-Alania. Methods. The features of geo-ecological location of North Ossetia are determined. The main features are: hollowed location of the cardinal planar part of Ossetia, the fact that it is surrounded by mountains; extremely low probability of wind; low degree of atmospheric air self-purification; high level of streamflow autonomy(excluding the district of Mozdok); considerable density of federal highways with high traffic load and as a result – aggravation of ecological situation; concentration of mining, processing and dressing factories of non-ferrous metallurgy, tailing ponds, clinkers in the republic; advanced distillery production with a virtual absence of sewage treatment plants. Results. It was revealed that air contamination level in the republic increases constantly. And that is despite the fact that atmospheric emissions from stationary sources have been decreased dramatically, especially emissions from “Electrozinc” plant. Air contamination level increases on account of  increase of vehicles and transit transport. Overwhelming majority of vehicles are concentrated in Vladikavkaz. As a result the contamination level of atmospheric air in the capital of the republic is several times higher than in other districts. This applies both to the absolute( emissions, tonnes) and relative(emission per unit area of land, tons / sq. km) indicators. Mozdoksky district is on the second place in absolute pollution. These areas turned out to be the leaders in sickness rate – Vladikavkaz in adult morbidity, and Mozdoksky district – in child morbidity. Similar situation can be observed in other districts: areas with high pollution level have higher morbidity rate, and areas with low pollution level have lower morbidity rate. Conclusions. The studies have shown a high level of correlation between pollution degree and the level of children and adult morbidity. Nevertheless other factors should be also taken into consideration like wind rose, naturally high level of radiation (e.g. – Digorsky Gorge) and many others.Keywords: North Ossetia, districts, en- vironmental pollution, population, emission, morbidity, dependence.
