In this study, human exposure and risks of metals through fish ingestion were predicted. Concentrations of 10 metals (Cd, As, Cr, Cu, Hg, Mn, Ni, Pb, V, and Zn) in 17 commonly eaten fish species in Saudi Arabia were characterized. Using the fish ingestion patterns, chronic daily intakes of metals among the Saudi and expatriate populations were predicted to be in the ranges of 8.89 × 10−06–1.08 × 10−02 and 6.59 × 10−06–7.97 × 10−03 mg/kg/day, respectively. The average cancer risks from inorganic arsenic were 2.76 × 10−05 and 2.09 × 10−05 for Saudi and expatriate, and the ranges were 1.61 × 10−09–1.58 × 10−03 and 2.64 × 10−09–1.27 × 10−03, respectively. The predicted risks were much lower than the previously reported risks. There were 47.4% and 42.4% chances that cancer risks would be higher than 1.0 × 10−05 (10 per million) among Saudi and expatriate, respectively. The average cumulative hazard index (HI) for Saudi and expatriate were 0.324 and 0.239 with the ranges of 0.0142–7.26 and 0.017–6.43, respectively. Approximately 3.06% and 1.56% cases among Saudi and expatriate had HI greater than unity, indicating possible health concern, respectively. Through comprehensive understanding of exposure and risks, strategies can be adopted to protect human health.

沙特阿拉伯通过鱼类和贝类食物摄入金属而导致的人类健康风险

在这项研究中,预测了人类接触和通过鱼类摄入金属的风险。对沙特阿拉伯17种常见食用鱼类中10种金属(镉,砷,铬,铜,汞,锰,镍,铅,钒和锌)的浓度进行了表征。使用鱼的摄入方式,沙特和外籍人口的长期每日金属摄入量预计为8.89×10 −06 –1.08×10 −02至6.59×10 −06 –7.97×10 −03  mg /公斤/天。沙特和外籍人士的平均无机砷癌症风险为2.76×10 -05和2.09×10 -05,范围为1.61×10 −09 –1.58×10 -03和2.64×10分别为−09 –1.27×10 −03。预测的风险远低于先前报告的风险。沙特和外籍人士分别有47.4%和42.4%的机会罹患癌症的风险高于1.0×10 -05(百万分之十)。沙特阿拉伯人和外籍人士的平均累积危害指数(HI)分别为0.324和0.239,范围分别为0.0142-7.26和0.017-6.43。沙特和外籍人士中约3.06%和1.56%的HI大于1,表明可能存在健康问题。通过全面了解暴露和风险,可以采取策略来保护人类健康。
