An epidemiological study of industrial emissions and cancer incidence in Contra Costa County, California, is described. Areas of the county were classified as industrial or nonindustrial based on census tract data, and cancer incidence data since 1969 was analyzed for each census tract. Occupational monitoring was planned to determine whether any labor union or working group had a higher incidence rate for any cancer site than other labor or working groups in the county. A study of 150 cases of lung cancer and a matched comparison group of 300 persons was planned to identify the major factors associated with the difference in lung cancer rates between the industrialized and nonindustrialized parts of the county. Air samples were collected at 15 stations and analyzed for total suspended particulates, inorganic substances, organic substances soluble in benzene, polycyclic aromatic hydrocarbons, and mutagenicity. Air sampling data was being used in a modeling technique to characterize the census tracts by estimating a value for each air pollutant measured. The incidence of lung cancer was significantly higher for males in the industrialized area of the county than for those in nonindustrialized areas. The authors suggest that the study should help in determining the role of occupational and environmental exposure to industrial emissions in cancer induction.
