In this investigation, δC and δN isotope ratios and heavy metal levels were assessed in macroalgae, sediment samples, and benthic species from northern parts of the Persian Gulf and the Gulf of Oman. The highest δN values in algal samples (11±0.42), indicative of anthropogenic organic N inputs, were detected in the Sadaf region, whereas the lowest values (3.17 ± 0.12), indicative of anthropogenic inorganic inputs, were detected in the Parvaz region. In addition to sediment quality guidelines (SQGs), contamination factors (CF), enrichment factors (EF), contamination degree (CD), pollution load index (PLI), geo accumulation index (Igeo), and potential ecological risk index (RI) were employed to assess the anthropogenic influence on sediment quality and to describe the sensitivity of the biota to toxic heavy metals. The obtained results demonstrate that the analyzed elements (Mn, Cr, Ni, Pb, Zn, Cu, Co, and V) had no ecological risk in the sampling area.
在这项研究中，我们评估了波斯湾北部和阿曼湾的大型藻类、沉积物样本和底栖物种的 δC 和 δN 同位素比值以及重金属水平。在 Sadaf 地区，藻类样本中的 δN 值最高（11±0.42），表明存在人为有机氮输入，而在 Parvaz 地区，δN 值最低（3.17±0.12），表明存在人为无机氮输入。除了沉积物质量指南（SQGs），我们还采用了污染因子（CF）、富集因子（EF）、污染程度（CD）、污染负荷指数（PLI）、地质累积指数（Igeo）和潜在生态风险指数（RI）来评估人为因素对沉积物质量的影响，并描述生物对有毒重金属的敏感性。结果表明，在采样区域，分析的元素（Mn、Cr、Ni、Pb、Zn、Cu、Co 和 V）没有生态风险。
