In this study, heavy metal levels in sediments, human hair, and fish muscle tissue as well as organic matter (OM%) content in surface sediments of Chabahar Bay were determined to assess their ecological risks and sources. Totally, 96 samples were collected from 16 stations (Tiss, Konarak, desalination plant, entrance of Chabahar Bay, Posm, Ramin, and reference stations) and were analyzed using inductively coupled plasma mass spectrometry (ICP-MS). Abundances of elements were of the following order: Ca>Al>Fe>Mg>Na>K>S>P>Ti>Mn>Sr>Ba>Cr>Ni>V>Li>Zn>Cu>Co>Pb>As>Cd>Ag>Se>Sb>Be>Mo>Bi. Element levels in sediments were within the range of low pollution areas, except for Cr, As, Ni, and Cd. Dominant sources of elements were natural, except for Cd, which was anthropogenic. All geo-accumulation index (I_geo) values were less than zero, except for Ag, Cd, and Sr from heavily to moderately contaminated areas. E_rⁱ values indicated low ecological risk, except for Cd which showed a high ecological risk. The As levels limit the consumption of fish meal per month.

本研究通过测定恰巴哈尔湾沉积物、人毛发和鱼肌肉组织中的重金属含量以及表层沉积物中的有机物（OM%）含量来评估其生态风险和来源。总共从16个站点（Tiss、Konarak、海水淡化厂、Chabahar Bay入口、Posm、Ramin和参考站点）收集了96个样品，并使用电感耦合等离子体质谱（ICP-MS）进行了分析。元素丰度为：Ca>Al>Fe>Mg>Na>K>S>P>Ti>Mn>Sr>Ba>Cr>Ni>V>Li>Zn>Cu>Co>Pb>As >Cd>Ag>Se>Sb>Be>Mo>Bi。沉积物中除Cr、As、Ni、Cd外的元素含量均在低污染区范围内。元素的主要来源是天然的，除了人为的 Cd。) 值小于零，除了 Ag、Cd 和 Sr 从重度到中度污染区域。Ë _[R^我值所代表的低生态风险，除镉，其表现出很高的生态风险。As 水平限制了每月鱼粉的消费量。
