ResumoAbstract Models for assessing associations between environmental risks and cancer are becoming increasingly important in epidemiology. Studies relating air pollution levels to cancer mortality or morbidity may employ models of varying complexity to predict ground-level dosages. This study utilizes a simple method based on the inverse of distances from point sources, weighted by annual average emissions, to create an industrial emissions score for each census tract in two industrialized Texas counties. In a case-control study of liver cancer, residential patterns at time of death were evaluated utilizing a model in which the appropriate census tract scores were assigned to study subjects. The hypothesis that there was no difference between cases and controls in their proximity to industrial plants was tested and could not be rejected. No interaction between employment status and proximity scores was observed.
