Abstract

Pollution of the environment, besides doing harm to nature, leads to various diseases of the population living in the contaminated area, including cancer diseases. Environmental pollution of the territory of the Republic of North Ossetia-Alania is mainly caused by enterprises of non-ferrous metallurgy and motor transport. Vladikavkaz, the capital of the republic, where the main stationary sources of pollution are located and the number of vehicles is the largest, is exposed to the hardest pollution. In rural areas of the republic, the state of atmospheric air is consistently satisfactory because of the absence of large industrial enterprises in the countryside and a smaller number of motor transports. The material on the population morbidity of malignant growth in various regions of Vladikavkaz was selected. The functional dependence of the patients' percentage on the age group with a high value of approximation reliability was obtained. The main proportion of newly registered malignant neoplasms falls to age groups over 60 years. The analysis of cancer morbidity showed that in the areas of the republic, as well as in Vladikavkaz, where the level of environmental pollution is higher, the rates of cancer morbidity are higher.
