Abstract

Abstract: The distribution of cadmium in Xenopus laevis was studied polluted by cadmium. X. laevis was exposed to 0.5 mg/L, 1 mg/L and 5 mg/L cadmium respectively. After 30 days of cultivation, the kidney, muscles and reproductive organs of X. laevis were dissected and measured to investigate the accumulation and distribution of cadmium in X. laevis. The results showed that the cadmium content in kidney, genital organ and muscle was significantly different ( p < 0.05), after long-term treatment with cadmium. Compared with the control group, in 0.5, 1 and 5 mg/l treatment groups, the content of cadmium increased by 3.83, 5.34 and 3.60 times in muscle respectively, by 5.45, 8.99 and 9.04 times in kidney respectively, and by 3.86, 5.23 and 7.69 times in reproductive organs respectively. This study confirmed that the accumulation of cadmium in X. laevis increased significantly after cadmium treatment, but the distribution of cadmium in various organs was uneven.
