Occupational and Environmental Exposure Assessment

Occupational Exposure Assessment

Evaluation of exposure-response relationships is a crucial component in assessment of causes of cancer. Quantitative exposure assessment is therefore an essential element in high-quality epidemiologic investigations. The Occupational and Environmental Epidemiology Branch devotes considerable effort to improving exposure assessment techniques and evaluating the reliability and validity of procedures used in cohort and case-control studies of occupational and environmental exposures.

Use of Remote Sensing Data and a Geographic Information Systems (GIS) in Cancer Epidemiology

The possible link between occupational exposure to certain pesticides and the risk of non-Hodgkin's lymphoma raises a concern about nonoccupational exposures. A methodologic project has been designed to investigate the feasibility of using remote sensing data and a GIS to reconstruct general environmental exposures. This project links satellite imagery data on cropping patterns with U.S. Department of Agriculture information on agricultural chemical use to estimate pesticide application on farmland adjacent to residential communities.
