Oreochromis niloticus was subjected to sub-lethal Cd and Zn concentrations for 14 days in order to evaluate their accumulation in the gills, liver, and muscle. Following that, the fish were placed to uncontaminated water for 7 days to allow the metals to be removed from the tissues. The gills had the highest bio-concentration factor for Cd and Zn. The gills showed the highest Cd accumulation rate, and the muscle showed the lowest. The muscle had the highest Cd depuration rate, while the liver had the lowest. The liver exhibited the highest Zn accumulation rate, while the gills and muscle had nearly similar values. Zn depuration rates were very consistent across all tissues.
奥利亚罗非鱼在亚致死浓度的 Cd 和 Zn 环境下暴露 14 天，以评估它们在鳃、肝和肌肉中的积累。随后，将鱼放入未受污染的水中 7 天，以将金属从组织中去除。鳃对 Cd 和 Zn 的生物浓缩因子最高。鳃显示出最高的 Cd 积累率，而肌肉则显示出最低的。肌肉显示出最高的 Cd 净化率，而肝脏则显示出最低的。肝脏显示出最高的 Zn 积累率，而鳃和肌肉的值几乎相似。Zn 的净化率在所有组织中都非常一致。
