在亚致死浓度镉(100mU·g/L)下，双壳软体动物贻贝和十字贝鳃的金属结合特性和金属硫蛋白的诱导有明显差异。与十字甲藻相比，高氏沼虾鳃对镉的吸收速率和结合到细胞质中的镉的百分率都显着高于十字甲藻。类似地，高氏沼虾鳃中检测到的金属硫蛋白浓度增加了四倍，而十字贝鳃中金属硫蛋白浓度只增加了两倍。(C)1998年爱思唯尔科学公司。
Metal binding characteristics and metallothionein induction differ markedly among the gills of the bivalve molluscs Mytilus galloprovincialis and Ruditapes decussatus exposed to sublethal cadmium concentrations (100 mu g/l). The rates of cadmium uptake as well as the percentage of cadmium bound to the cytosol were significantly higher in the gills of M. galloprovincialis when compared with that of R. decussatus. Similarly metallothionein concentration detected in the gills of M. galloprovincialis increase fourfold while for the clam R. decussatus metallothionein concentrations increased only twofold.
