Abstract Niigata prefecture (Japan) has a very high mortality rate from biliary tract cancer. There is a correlation between the standardised mortality ratio (SMR) for biliary tract cancer and the amount of certain agricultural chemicals consumed. Agricultural chemicals were detected in cholesterol gallstones of 99 patients, including 11 patients with gallbladder cancer. DLD, pp'-DDT, β-BHC and PCB were detected in the gallstones, even though the epidemiological study showed no positive correlation between them and the SMR for biliary tract cancer. MCPA, MCPB, CNP and simetryn, which did show significant correlations with the SMR, were not detected. Further investigation of the biliary excretion of the metabolites of these chemicals is indicated.
