| Abstract: | Accumulation, desorption and BCF of DMA in fish and algae were studied under the aquatic ecosystem model in this paper. Experimental results indicated that BCF of DMA after 3, 5 and 6d was 3.53, 4.73 and 5.29,respectively. The amount of DMA accumulation in the following tissue was increased in order of viscera > head >muscle. 7 days later, the cumulative amount of DMA in fish was the highest; after 6h, the amount of DMA accumulated in algae was highest. Cumulative ratios of DMA in water to algae and fish (viscera) were 1 : 3 and 1 : 12, respectively. |
