In the current study contents of As, Cd, Cu, Co, Pb, and Sn were determined in the caviar of Persian sturgeon collected from Southern Caspian Sea sampling site. After acid digestion of caviar specimens, the concentrations of elements determined using ICP-OES. The results showed that the mean concentrations (mg kg) of elements in caviar samples were 0.01 for As, 0.05 for Cd, 1.42 for Cu, 0.01 for Co, 0.01 for Pb, and 0.28 for Sn and for all the elements are significantly lower than the adverse level for the human consumption. Also, health risk index (HRI) values were within the safe limits (HRI < 1). Therefore, there is no potential health risk to adults and children via consumption of caviar. Due to the discharge of hazardous chemicals into the marine ecosystems especially the Caspian Sea, residue analysis of pollutants in the sea foods is recommended.
在本研究中，测定了来自里海南部采样点的鲟鱼子酱中的砷、镉、铜、钴、铅和锡。在对鱼子酱样本进行酸消解后，使用 ICP-OES 测定了元素浓度。结果表明，鱼子酱样本中元素的平均浓度（mg/kg）分别为：砷 0.01、镉 0.05、铜 1.42、钴 0.01、铅 0.01、锡 0.28，所有元素的浓度均显著低于人类食用的有害水平。此外，健康风险指数（HRI）值在安全范围内（HRI<1）。因此，成年人和儿童食用鱼子酱不存在潜在的健康风险。由于有害化学物质排放到海洋生态系统中，特别是里海，建议对海产品中的污染物残留进行分析。
