Heavy metals in sediments, mussels and oysters from Trinidad and Venezuela

Heavy metals were determined in oysters (Crassostrea rhizophorae and C. ica), green mussels (Perna viridis) and sediments from the Gulf of Paria. Samples were obtained at four sites in Trinidad and three sites in Venezuela in the Gulf of Paria, in addition to comparative samples collected from three sites on the north coast of Venezuela.
