摘    要:从天津污水鱼塘中采集了养殖的各种鱼,测定其鳃、肝、肾、肌肉等部位中的铜、铅蓄积量。并与水相金属形态化学平衡计算结果进行了比较。研究证实,铜、铅蓄积量在鱼体中呈对数正态分布,与不同鱼种无显著关系,但在各部位之间明显不同。由于吸收/排放的动力学差异,养殖后期鱼体中铅/铜蓄积比较中期低,反映了铅、铜相对蓄积速率的下降趋势。不同鱼塘鱼鳃的金属蓄积量与金属有效态含量呈正相关 

关 键 词:   金属   污水   形态   部位

Abstract:Fish of various species were collected from wastewater fishpond in Tianjin. Contents of copper and lead were measured for gill, liver, kidney and muscle of the fish. The metal speciation in the pond was calculated using chemical equilibrium modeling. It was found that the metal contents in the fish were lognormal distributed. Significant difference between various organs, rather than fish species, was revealed. Due to difference in kinetics of metal absorption and excretion, ratio of copper to lead decreased gradually, indicating that accumulation rate of lead declined during the second phase of the study period. The accumulation was positively correlated to the contents of bioavailable metal including hydrated and hydro complexed copper and lead.
Keywords:Fish  Metal  Wastewater  Speciation  Organ
