The heavy metal (Pb, Cd, Cr, and Ni) content of a fish species consumed by the Sistan population and its associated health risk factors were investigated. The mean concentrations of Pb, Cd, and Cr were slightly higher than the standard levels. The Ni content of fish was below the maximum guideline proposed by the US Food and Drug Administration (USFDA). The average estimated weekly intake was significantly below the provisional tolerable intake based on the FAO and WHO standards for all studied metals. The target hazard quotients (THQ) of all metals were below 1, showing an absence of health hazard for the population of Sistan. The combined target hazard quotient for the considered metals was 26.94 × 10. The cancer risk factor for Pb (1.57 × 10) was below the acceptable lifetime carcinogenic risk (10). The results of this study reveal an almost safe level of Pb, Cd, Cr, and Ni contents in the fish consumed by the Sistan population. Graphical abstract ᅟ.
对锡斯坦地区居民食用的一种鱼类的重金属（铅、镉、铬和镍）含量及其相关健康风险因素进行了调查。铅、镉和铬的平均浓度略高于标准水平。鱼类中的镍含量低于美国食品药品监督管理局（USFDA）提出的最大指导值。基于粮农组织和世卫组织标准，所有研究金属的平均估计每周摄入量均显著低于暂定可耐受摄入量。所有金属的目标危险商（THQ）均低于1，表明锡斯坦地区居民不存在健康危害。所考虑金属的综合目标危险商为26.94×10。铅的癌症风险因素（1.57×10）低于可接受的终生致癌风险（10）。本研究结果表明，锡斯坦地区居民食用的鱼类中铅、镉、铬和镍的含量几乎处于安全水平。图形摘要ᅟ
