Abstract
The article reports on the contamination in the canals of Ho Chi Minh City in Vietnam. Ho Chi Minh City is situated in a transitional delta formed by two rivers Saigon and Dong Nai. The contaminants found in the canals of Ho Chi Minh are polychlorinated biphenyls (PCB), dichlorodiphenyltrichloroethane (DDT) and heavy metals in sediments. PCBs and DDTs are recognized since long time as persistent hazardous environmental contaminants and appear in the priority pollutant list of some western countries. Sediments are also sensitive indicators for both spatial and temporal trends.
