| 摘 要： | 在水相溶解态铜浓度和高岭土吸附态铜浓度保持不变，pH和高岭土粒径不同条件下，研究了鲤鱼鱼鳃对铜的吸收。结果表明在本研究范围内，吸附态铜的存在增加了鱼鳃吸收。鳃对铜的吸收随pH增加而递增，随高岭土粒径减少而递增。利用MINTEQA2软件分析了不同实验条件下鱼鳃微环境中铜的形态分布特征，对吸附态铜可能的生物有效性机制进行了说明。

| Abstract: | Carps were exposed to copper adsorbed on kaolin at various conditions. Both particle size of kaolin and pH level were examined for their influences on the copper speciation and bioavailability. The fish was exposed to copper adsorbed on kaolin of various sizes (150, 200,300,400 meshes) at a fixed pH level of 7.53. Exposure experiment was also conducted at various pH levels (5.60, 6.95, 7.20, 7.53) with identical kaolin particle size of 400 meshes. The accumulation of copper on the fish gills was measured us... |
