Abstract：
The main objectives of this study were to determine the mercury concentration in four species of valuable and widely consumed fish from the Caspian Sea, to assess the health risk due to their consumption. The average mercury concentrations for Chelon saliens, Chelon auratus, Acipenser persicus and Acipenser stellatus were 32.72, 39.51, 166.87 and 81.87 μg g-1 dw, respectively. There were correlations between the mercury concentrations in the muscle of Chelon saliens and morphological parameters, but these correlations were not observed in Chelon auratus. Our comparison of the mercury values obtained in all the samples with the recommended international standards, as well as the Hazard Quotients values, indicated that there is no potential risk for the health of consumers due to exposure to mercury from consuming these fish.
摘要：
这项研究的主要目的是确定来自里海的四种有价值且广泛食用的鱼类中的汞浓度，评估他们消费带来的健康风险。Chelonsaliens的平均汞浓度，Chelonauratus,Acipenserpersicus和Acipenserstellatus分别为32.72、39.51、166.87和81.87μgg-1dw，分别。Chelonsaliens肌肉中的汞浓度与形态参数之间存在相关性，但是在Chelonauratus中没有观察到这些相关性。我们将所有样品中获得的汞值与推荐的国际标准进行了比较，以及危险商值，表明，由于食用这些鱼类而接触汞，对消费者的健康没有潜在风险。
