| A radiotracer study was conducted to evaluate the influence of body size and temperature on the uptake rates of Cd, Se and Zn in the California mussel, Mytilus californianus. Uptake rates of Cd, Se and Zn were determined simultaneously with clearance of the mussels with 3 different size classes (0.07, 0.24 and 0.73 g flesh dry weight $individual^{-1})$ and at 4 different temperatures (3, 8, 13 and $21^circ{C})$. The weight-specific uptake rates of 3 elements significantly decreased with body size, but increased with temperature. Simultaneously measured clearance rates of mussels were closely associated with metal uptake rates. The significant association of clearance rates and metal uptake rates of mussels emphasizes the importance of functional role of water pumping activity in the metal uptake process in filter-feeding organisms |
