Accumulation of cadmium in gill, liver, muscle and kidney tissues of Cyprinus carpio and Oreochromis niloticus were investigated in fish exposed to 0.5 ppm cadmium over 1, 15 and 30 days under controlled laboratory conditions. Tissue accumulation of the metal was measured using Atomic Absorption Spectrophotometric techniques. Cadmium accumulation in gill, liver, kidney and muscle, tissues of C. carpio and O. niloticus exposed to metal for 1, 15 and 30 days increased significantly compared with the control group (p < 0.05), except muscle tissue of O. niloticus. A general increase was observed in Cd accumulation with increasing exposure periods. Highest metal accumulation was observed in kidney followed by liver, gill and muscle tissues in both species. Liver accumulation of Cd was higher in C. carpio than O. niloticus, whereas kidney accumulation of the metal was higher in O. niloticus than C. carpio.
在控制实验室条件下，将鲤鱼和罗非鱼暴露于 0.5ppm 的镉中 1、15 和 30 天后，研究了镉在鱼的鳃、肝、肌肉和肾脏组织中的积累。使用原子吸收分光光度技术测量金属在组织中的积累。与对照组相比（p<0.05），暴露于金属 1、15 和 30 天后，鲤鱼和罗非鱼的鳃、肝、肾和肌肉组织中的镉积累显著增加，除了罗非鱼的肌肉组织。随着暴露时间的增加，Cd 积累呈普遍增加趋势。在这两个物种中，最高的金属积累量出现在肾脏中，其次是肝脏、鳃和肌肉组织。鲤鱼肝脏中 Cd 的积累量高于罗非鱼，而罗非鱼肾脏中金属的积累量高于鲤鱼。
