Popis: Japan was associated with the rice production per area prompted us to test the role of agricultural chemicals on the occurrence of cancer. For the examination of agricultural chemicals, an environmental pollution index (EPI) was introduced. The index refers to the quotient obtained by dividing a total amount of agricultural chemicals annually distributed to each prefecture by the area of the prefecture. Then, Pearson's correlation analysis was made between EPIs from 1962 to 1975 and SMR in 1975. The number of chemical products subjected to analysis was about 300 every year. Among these chemicals, EPIs of phenoxy herbicides, MCPA and MCPB were frequently associated with the SMR for biliary tract cancer.
