The concentration of potentially toxic elements (PTEs; Lead (Pb), Nickel (Ni), and Cadmium (Cd) Pb, Ni, and Cd), using flame atomic absorption spectrometry (FAAS) was measured in fifty surface coastal sediment samples collected from 5 points coastal sediment of Bandar Abbas city, Iran besides the potential ecological risk index (RI) estimated the environmental health risk. The rank order of PTEs was Pb (52.090 ± 4.113 mg/kg dry weight) > Ni (34.940 ± 8.344 mg/kg dry weight) > Cd (2.944 ± 0.013 mg/kg dry weight). RI due to PTEs in sediments for A, B, C, D, and E points were 187.655, 190.542, 191.079, 189.496, and 192.053, respectively. RI for sampling points A to E was at moderate risk (150 ≤ RI < 300). Therefore, it is recommended to carry out control programs to reduce the amount of PTEs in the coastal sediment of the Persian Gulf.
使用火焰原子吸收光谱法（FAAS）测量了从伊朗班达尔阿巴斯市 5 个沿海地点采集的 50 个表层沿海沉积物样本中的潜在有毒元素（PTEs；铅（Pb）、镍（Ni）和镉（Cd）、Pb、Ni 和 Cd）的浓度，并估计了潜在生态风险指数（RI），以评估环境健康风险。PTEs 的浓度顺序为 Pb（52.090 ± 4.113 mg/kg 干重）> Ni（34.940 ± 8.344 mg/kg 干重）> Cd（2.944 ± 0.013 mg/kg 干重）。由于沉积物中的 PTEs，A、B、C、D 和 E 点的 RI 分别为 187.655、190.542、191.079、189.496 和 192.053。采样点 A 至 E 的 RI 处于中等风险（150 ≤ RI < 300）。因此，建议实施控制计划以减少波斯湾沿海沉积物中 PTEs 的含量。
