| 摘 要： | 对威海近海海域127站位表层沉积物中的重金属元素进行分析测试,采用单因子污染指数法、综合污染指数法、超标分类法和潜在生态危害法等多种评价方法对研究区环境质量进行评价。认为研究区海底表层沉积物的单因子污染物指数偏低,只有Cu和Cr两种重金属出现一类沉积物质量超标情况;海底表层沉积物环境质量在整体上处于清洁和尚清洁状态,个别站位处于允许状态;污染类型主要以Ⅰ类、Ⅱ类为主,含少量Ⅲ类,Ⅱ类又分为Ⅱ1Cr和Ⅱ2Cu两个污染亚类,Ⅲ类又分为Ⅲ1Cr-Cu和Ⅲ2Cu-Cr两个污染亚类;各种重金属的生态危害程度均低。

| Abstract: | The heavy metal elements in surface sediments of 127 stations in Weihai offshore area have been analyzed and tested.The environmental quality of the study area has been evaluated by using single factor pollution index method,comprehensive pollution index method,over-standard classification method and potential ecological hazard method.The evaluation results are as follows:the single factor pollutant index of seabed surface sediments in the study area is low,only two heavy metals as Cu and Cr are found to exceed the standard of one kind of sediments.The environmental quality of seabed surface sediments is in a clean state as a whole,and individual stations are in a permissible state.The pollution types are mainly in categoryⅠ.ClassⅡmainly contains a small amount of ClassⅢ.ClassⅡis divided into two sub-categories of pollution:ClassⅡ1Cr and ClassⅡ2Cu.ClassⅢis also divided into two sub-categories of pollution as ClassⅢ1Cr-Cu and ClassⅢ2Cu-Cr.The ecological hazards of various heavy metals are low. |
