ABSTRACT
The present-day ecological crisis progressively deteriorates the population's health and demographic indices. Since 1990 primary morbidity has shown a 50.2% increase in the town of Samara. There has been a rise in the incidence of diseases, primarily those of the blood, digestive, respiratory, and other systems. A correlation analysis revealed that there was an association of morbidity with the environmental content of specific industrial chemical pollutants. The incidence of respiratory diseases is related to the concentrations of CO, NO2 and SO2 in the ambient air.

A prospective cohort research revealed an increased morbidity level among oil-processing workers with chronic pretumour diseases (chronic bronchitis, anacid gastritis, ailments of the larynx and skin, diseases of cervix uteri, benign tumour of the uterus and pretumour mammary gland diseases). Statistically reliable data have been received with regard to lung cancer mortality of males in the sample cohort, and lung and cervix uteri cancer mortality of females, as well as the risk factors of lung, larynx and skin cancer in males, and lung and large intestine cancer in females,--all in comprison with workers who have no contact with oil-processing products.

In a large industrial Povolzhje region-Kuibyshev Province, within a 15-year period according to standardized indices the incidence of malignancies increased by 71.9% (1956-133,7; 1973-229,9; Pt = 0.95) It prevailed among urban population in relation to cancer of the breast and other organs; no reliable differences were found in relation to cancer of the lung, larynx, esophagus, stomach and skin. The incidence of cancer of the lower lip and female genitalia was higher in rural population. In the central industrial complex, where all cities and industrial enterprises are concentrated, the incidence rate among the rural population is higher than the average provincial one (100), so cancer of the upper respiratory tract is 129.5, esophagus--118, stomach-114, breast-115. The incidence rate is mostly high in cities with machine, petrochemical, electrical industry enterprises and aged population.
