摘要
通过残毒分析发现，重庆江段的鱼体受到不同程度的污染。鱼体中主要污染物Ｃｄ、Ｃｒ、Ａｓ等的负荷比较高，但未超标，食用品质较好。鱼样外周血红细胞微核率为０８２‰～４２８‰，表明重庆江段水质对鱼体细胞具诱变作用。
According to the residual analysis, the main pollutants in the fish bodies from Chongqing section of the Yangtze River are Cd, Cr, As, etc. Their loading ratios are relatively high, but the quality of the major fishes as edible ones is still fine.The mini cell nucleus (MCN) ratios of red blood cells in different fishes are 0 82‰～4 28‰. The water quality there may induce the mutation of the cell nucleus in the fishes.
