The aim of this study, fourteen potential toxic elements (PTE) levels were measured in seven different fish consumed intensively in eight provinces along the Black Sea coastline of Türkiye. Furthermore, human health risk assessment from fish consumption was investigated using multiple statistical approaches, and a spatial distribution map of PTEs in the region was prepared. The average PTEs levels in the seven fish muscle are listed in the following order: Fe > Zn > As > Cu > Mn > Ni > Co > Hg > Cd > Pb > Cr with the values of 17.028 > 14.288 > 2.045 > 1.017 > 0.721 > 0.064 > 0.032 > 0.031 > 0.027 > 0.021 > 0.018 µg g-1, respectively. In the seven fish species examined, the sum of the mean values of toxic metals and essential metals was lowest in MM (18.75 µg g-1) and highest in EE (58.16 µg g-1) and MB (57.66 µg g-1 ). The maximum values of PTEs measured in fish were mostly observed in the provinces of Kastamonu, Sinop, Artvin and Rize. For all PTEs, hazard index (HI), target hazard quotients (THQ) and metal pollution index (MPI) from metal intake by ingesting seven fish species were less than 1, indicating no risk from consumption. It can be said that there is unlikely to be a risk of potential cancer issues in those who consume the fish used in this study, as the estimated daily PTEs intakes in fish were found to be much lower than acceptable daily intake levels. It is recommended to introduce biomonitoring species to these areas and to take preventive measures against metal pollution in order to monitor metal pollution from industrial and discharge areas, to identify, monitor and compare heavy metal sources.
本研究的目的是测量土耳其黑海沿岸八个省份大量消费的七种不同鱼类中十四种潜在有毒元素（PTE）的含量。此外，采用多种统计方法调查了食用鱼类对人类健康的风险评估，并绘制了该地区PTE的空间分布图。七种鱼类肌肉中PTE的平均含量按以下顺序列出：铁＞锌＞砷＞铜＞锰＞镍＞钴＞汞＞镉＞铅＞铬，其值分别为17.028＞14.288＞2.045＞1.017＞0.721＞0.064＞0.032＞0.031＞0.027＞0.021＞0.018μg g-1。在所检查的七种鱼类中，有毒金属和必需金属的平均值总和在MM中最低（18.75μg g-1），在EE中最高（58.16μg g-1）以及在MB中最高（57.66μg g-1）。在鱼类中测得的PTE最大值大多出现在卡斯塔莫努、锡诺普、阿尔特温里泽等省份。对于所有PTE，通过食用七种鱼类摄入金属的危害指数（HI）、目标危害商（THQ）和金属污染指数（MPI）均小于1，表明食用无风险。可以说，食用本研究中所用鱼类的人群不太可能存在潜在癌症问题的风险，因为发现鱼类中PTE的估计每日摄入量远低于可接受的每日摄入量水平。建议在这些地区引入生物监测物种，并采取预防金属污染的措施，以监测来自工业和排放区域的金属污染，识别、监测并比较重金属来源。
