| 摘 要： | 根据在东营近岸海域采集的表层沉积物测试结果，系统研究了该区沉积物类型和重金属元素分布特征，并对其环境质量进行了评价。结果表明：东营近岸海域沉积物类型主要有5种，以砂质粉砂和粉砂为主。表层沉积物中重金属Hg、Cd、Pb、Cu、Zn、Cr和As元素的平均含量分别为0.019、0.12、21.53、22.4、73.02、67.02和12.77 μg/g。沉积物底质环境综合污染指数为0.27～0.73，平均为0.43，表明东营近岸海域底质环境大部分为清洁和尚清洁状态。研究区内表层沉积物重金属元素生态危害程度较低，污染程度顺序为As>Hg>Cd>Cu>Pb>Cr>Zn。

| Abstract: | Surface sediment samples collected from the offshore area of Dongying city are studied in this paper for sedimentology and heavy metals, by which environmental quality is evaluated. It is revealed that the surface sediments in the study area mainly include sand, silty sand, sandy silt, silt and mud dominated by silty sand and sandy silt. The sediments are getting finer off the coast towards the sea. The average contents of heavy metals Hg, Cd, Pb, Cu, Zn, Cr and As are 0.019, 0.12, 21.53, 22.4, 73.02, 67.02 and 12.77 μg/g respectively. The integrated pollution index of the study area ranges from 0.27 to 0.73, with an average of 0.43, all less than 1, indicating a rather clean environment. The ecological harm of heavy metal elements in surface sediments of the area is low, and the pollution degree is in an order of As>Hg>Cd>Cu>Pb>Cr>Zn. |
