[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.

[Assessment of the quality of drinking water in the industrial city and risk for public health].

Karabash city sprang up around the copper plant that uses local copper ore, which was composed of zinc, sulfur, barium, beryllium, arsenic, manganese, lead, antimony, chromium, cadmium, gallium, indium, scandium, thallium, germanium, osmium, and others. Centralized water supply for the city is organized from the lake Serebry and the flowage on the river B. Kialim.

[Assessment of children's health risk posed by traffic-related air pollution as exemplified by the city of Salekhard].

With the aim of determination of the levels of children's health risk from chemical air pollution caused by vehicle emissions, on the territory of the municipal district of the city of Salekhard there was carried out the work on the study of the intensity and the chemical structure of traffic-related air pollution in the locations of 16 children's preschool institutions. There was used the technique of the counting campaign for the structure and intensity of road traffic flows, children's health detriment was calculated according to the method of risk assessment. The main danger in the emissions of vehicles is belonged to nitrogen dioxide (43.

[Case-control study of lung cancer and combined home and work radon exposure in the town of Lermontov].

Relation between the risk of lung cancer and combined home and work indoor radon exposure was studied on the example of the population of Lermontov town (Stavropol Region, Russia). The town is situated in the former uranium mining area. Case (121 lung cancer cases) and control (196 individuals free of lung cancer diagnosis) groups of the study included both ex-miners and individuals that were not involved in the uranium industry.

[Analysis of the late irradiation effects in the population of the north part of the East-Urals radioactive track].

Death records were used to analyze cancer mortality in the rural areas of the Kamensky District, Sverdlovsk Region, within the East-Urals radioactive track area. A study group showed a significant increase in cancer mortality as compared with a control group (65 of the 691 examinees; 90% confidence interval (CI) 18-144; the mean colonic radiation dose was 80 and 3 mGy in the study and control groups, respectively). The additional relative risk per colonic dose was 1.
