Water, suspended solid (SS) and sediment samples were collected from nine water courses in Tianjin, China and analyzed for dichlorodiphenyltrichloroethane (DDT) and its metabolites (DDXs, including o, p′-, p, p′-DDT, DDD and DDE). The average DDX concentrations in water, SS and sediment were 59 ± 30...
