摘要
1991年4月25日在河北省安新县测定白洋淀两个点水样及3种鱼的无机元素共19种。分析结果表明水质未受污染,仅有一个点锰的含量达0.2mg/L,稍超过饮用水,其它各项均低于饮用水标准。3种鱼类的痕量重金属均低于允许量或未检出。白洋淀鱼类银的含量高于其它水域,而铜未检出或量低。鱼类无机元素含量存在种间、不同产地的差异。
In this paper, 19 mineral elements in 3 species of fishes and 2 water samples from Baiyangdian Lake in Anxin county of Hebei Province were tested on April 25,1991. The results showed the content of Mn (0. 2mg/L) exceded the standard of drinking water while the others were all lower than the standard. So it can be said the water hadn't been polluted. The contents of trace heavy metals in 3 fishes were lower than the permitted contents or were not detected. The content of Mo in Baiyandian Lake was higher than the other waters, but the content of Cu was not detected or was low. The conteants of mineral elements in fishes differ in species and areas.
