Uptake and Depuration of Carbofuran by the Fish and Clam in Water
鱼(Tilapia nilotica)、蚌(Anoclonta woodiana)对水中呋喃丹的吸收和排除

There was no significant accumulation of carbofuran in the fish Tilapia nilotica,but a slight accumulation occurred in the clam Anodonta woodiana. Depuration of carbofuran in the fish and clam after being transfered to carbofuran-free water was rapid.Depuration of carbofuran from dead clam was much slower than living ones. This indicated that physiological and biochemical processes had a significant effect on the depuration of carbofuran from the clams.It was shown that clams could reduce the pH value in water. Because of biodegradation by the clams,the degradation of carbofuran in water was enhanced.In a simulation experiment,it was shown that absorption of carbofuran by bottom mud was not significant.
