This study was performed to investigate the effect of chitin, chitosan and dithiocarbamate chitosan against cadmium accumulation. The Scapharca subcrenata were divided into four independent groups which were one control and three experimental groups by cadmium alone treatment or chitin, chitosan and dithiocarbamate chitosan which cadmium. Samples were analyzed by Varian 30/40 atomic absorption spectrophotometer. The results obtained were as follows; 1. The cadmium concentration in water were significantly decreased in three experimental groups compared with that of control group(P<0.05). 2. The cadmium concentration in muscle of S. subcrenata in cadmium alone treatment group were similar to that of the chitin treatment group, but chitosan and dithiocarbamate chitosan treatment groups were significantly decreased(P<0.05). In conclusion, this study revealed the effect of chitin, chitosan and dithiocarbamate chitosan against cadmium accumulation. It exhibited the highest effect at dithiocarbamate chitosan treatment group.
