Abstract The concentrations of DDT and its metabolites in 19 sediments samples from a highly developed agricultural region in the upper reaches of the Yangtze River were measured. Non-cancer hazard quotient for different age groups was evaluated using reference doses given by the USEPA, and the excess lifetime cancer risk due to eating fish was assessed based on the local eating habits. The results showed that this region has a high level of residual DDT (12.84 ± 8.97 ng/g), which mainly came fr
