摘要/Abstract

摘要： 为了解乌江沙坨电站库区鱼类重金属富集状况及食品安全,利用电感耦合等离子体原子发射光谱法（ICP-AES）和原子荧光光度法（HSHG-AFS）测定了该库区大口鲇（Silurus meridionalis）和黄颡鱼（Pelteobagrus fulvidraco）肌肉中Cu、Zn、Mn、Pb、Cd、Cr、Ag和Hg的含量。结果表明,大口鲇和黄颡鱼肌肉中不同重金属含量存在差异,其中Zn在两种鱼肌肉中含量均最高, Cu、Cr、Pb和Hg在黄颡鱼肌肉中含量均高于大口鲇,均低于国家标准。危害指数分析表明,食用乌江沙坨电站库区大口鲇和黄颡鱼的健康风险较小。重金属单因子污染指数结果显示,两种鱼体肌肉中Pb、Hg和Cd的污染程度相对较高,乌江沙坨电站库区鱼类存在潜在的重金属污染风险。

Abstract: In order to understand the present situation of heavy metal enrichment and food safety of fish in the Shatuo reservoir of the Wujiang river, the heavy metal content in the muscle of Silurus meridoualis and Pelteobagrus fulvidraco were determined by inductively coupled plasma emission spectrometry （ICP-AES） and atomic fluorescence spectrophotometry （HCHG-AFS）. The results showed that the contents of different heavy metals in the muscles of the fish were different, and the content of Zn in two kinds of fish muscles was the highest, and the content of Cu, Cr, Pb and Hg in the muscle of Pelteobagrus fulbate were all higher than that of S. meridoualis. The content of heavy metals in muscle of two species of fish was lower than the national standard. The results of hazard index showed that the human health risk of edible S. meridoualis and P. fulvidraco in the Shatuo reservoir of the Wujiang river was relatively small. The results of single factor pollution index of heavy metals showed that the pollution degree of Pb, Hg and Cd were high in fish from the Shatuo rreservoir, and there was a potential heavy metal pollution risk in the Shatuo reservoir of the Wujiang river.

Key words: Silurus meridionalis, Pelteobagrus fulvidraco, heavy metal, edible health risk assessment, Shatuo hydropower station reservoir
