| Abstract: | The relationship between sediment trace metals (Ag, Cd, Cr, Cu, Ni, Pb, Zn) and bioaccumulation in tissue of macrobenthos (Parvilucina tenuisculpta, Tellina spp., Macoma spp., Pectinaria californiensis, Nephtys spp., Glycera spp., Metasychis sp., Euphilomedes spp., and Ampelisca spp.) was described from 1975 to 1985 on the San Pedro Shelf, California. Results indicated that: 1) sediment trace metals were elevated at an ocean outfall station; 2) tissue trace metals were never statistically higher at the outfall compared to a reference station except for Zn in Macoma spp.; 3) there were a few statistically significant associations (r) between tissue and sediment metals, but no consistent trends emerged; 4) peak tissue metal concentrations occurred more frequently in the winter than in the summer. |
