Abstract

- A radiotracer study was conducted to evaluate the influence of body sizeand temperature on the uptake rates of Cd, Se and Zn in the California mussel, Mytiluscalifornianus . Uptake rates of Cd, Se and Zn were determined simultaneously withclearance of the mussels with 3 different size classes (0.07, 0.24 and 0.73 g flesh dryweight individual-1) and at 4 different temperatures (3, 8, 13 and 21 C). The weight -specific uptake rates of 3 elements significantly decreased with body size, but increa-sed with temperature. Simultaneously measured clearance rates of mussels wereclosely associated with metal uptake rates. The significant association of clearancerates and metal uptake rates of mussels emphasizes the importance of functional roleof water pumping activity in the metal uptake process in filter-feeding organisms
