A correlation between agricultural pesticides and cancer in Western states has been found by University of Idaho and Northern Arizona University researchers. Two studies were conducted, one that examined correlating data in 11 Western states and one that took a closer look at data in Idaho specifically.
The studies found a possible relationship between agricultural pesticides, particularly fumigants such as metam, and cancer incidences through analyzing data. For the larger study, pesticide data was pulled from the U.S. Geological Survey Pesticide National Synthesis Project database and cancer data was gathered from National Cancer Institute State Cancer Profiles, according to the study.
The other study examined Idaho specifically and found similar trends in data as the first study saw across the West of the lower 48 states.
