A multifactor assessment of effects of technogenic pollution on the occurrence of lung cancer in the population of an industrial town

: The study was devoted to the evaluation of technogenic geochemical pollution of the residential area of an industrial town and its effects on lung cancer incidence in the population living under severe exposure to emissions of a copper smelter plant. For mathematical treatment of epidemiologic data there were used methods of a system multifactor analysis based on pattern recognition principles. The result of the long-term operation of the copper smelter plant was established to become the intensive technogenic pollution of environment with carcinogenic substances. The contribution of environmental contamination in the lung cancer incidence of the population exposed to industrial emissions of the copper smelter was shown to be about 10%.
