This study was performed to determine the variation of metals concentrations (Pb, Cd, Zn, and Cu) in surface sediments based on type region development from ten sites on the intertidal coastal zone of the Persian Gulf, Iran. The metals concentrations in surface sediments varied from 0.86 to 180.78 μg g(-1) for Pb, 0.61 to 6.48 μg g(-1) for Cd, 5.99 to 44.42 μg g(-1) for Zn, and 3.01 to 43.33 μg g(-1) for Cu. The quality of the sediments was evaluated based on sediment quality guidelines (effects range-low (ERL) and effects range-medium (ERM) indexes. Biological effects criteria suggest that metals concentrations in sediments were lower than ERM for all sites, but for some sites metals concentrations in sediments were higher than ERL. The present results support the concept that human activities in each region could be a major source of metals pollution input in the aquatic environment.
本研究旨在确定波斯湾伊朗潮间带沿海地区十个地点的区域类型发展基础上的表层沉积物中金属浓度（Pb、Cd、Zn 和 Cu）的变化。表层沉积物中金属浓度的范围为 Pb 的 0.86 至 180.78μg/g，Cd 的 0.61 至 6.48μg/g，Zn 的 5.99 至 44.42μg/g 和 Cu 的 3.01 至 43.33μg/g。基于沉积物质量指南（效应区间低值 (ERL) 和效应区间中值 (ERM) 指标）对沉积物质量进行了评估。生物效应标准表明，所有地点的沉积物中金属浓度均低于 ERM，但对于一些地点，沉积物中金属浓度高于 ERL。目前的结果支持这样的概念，即每个地区的人类活动可能是金属污染输入水生环境的主要来源。
