This study was performed to investigate the effects of chitin, chitosan and dithiocarbamate chitosan on the cadmium accumulation in liver and kidney of catfish. The experimental groups were divided into four independent groups which were one control group and three experimental groups by cadmium alone treatment or chitin, chitosan and dithiocarbamate chitosan which cadmium. In order to investigate the effects of chitin, chitosan and dithiocarbamate chitosan on the cadmium accumulation in liver and kidney of catfish, the cadmium concentration, the metallothionein level were measured. The results obtained were as follows:
1. The cadmium concentrations in liver and kidney of catfish in cadmium alone treatment group were similar to that of the chitin treatment group, but chitosan and dithiocarbamate chitosan treatment groups were significantly decreased.
2. The metallothionein levels in liver and kidney of catfish alone treatment group were similar to that of the chitin treatment group, but chitosan and dithiocarbamate chitosan treatment groups were significantly increased.
In conclusion, this study revealed the effect of chitin, chitosan and dithiocarbamate chitosan against cadmium accumulation in liver and kidney of catfish. It exhibited the highest effect at dithiocarbamate chitosan treatment group.
