The Environmental Health Investigations Branch has developed a method to calculate pesticide exposure in humans based on location. Applying pesticide-use amounts into a GIS system has enabled researchers to observe exposure per year in census blocks. With data from 1991, high amounts of childhood exposure can be observed and potentially linked to childhood cancer.
