| 摘 要： | 根据2006年4月对涠洲岛潮滩表层沉积物的调查资料,分析了表层沉积物中重金属元素Hg、Cu、Pb、Zn、Cd、Cr、As的含量水平及空间分布特征,运用单因子评价法对其环境质量进行了评估,并通过相关性分析、因子分析探讨了几种重金属元素的物源.结果表明:涠洲岛潮滩环境质量状况良好,各元素均未达到污染水平,多数地区存在Cu的玷污,个别地区存在As的玷污;各分析元素较多的累积在人为活动相对频繁的XKZ、W05断面附近区域;Hg、Cu、Zn、Cr显著正相关,以环境背景来源为主,Pb、As较多的受到人为因素的影响. |

| Abstract: | According to the survey on intertidal surface sediments from Weizhou Island in April 2006,the contents and spatial distribution of heavy metals(Hg,Cu,Pb,Zn,Cd,Cr,and As)in surface sediments were analyzed.The quality of environment was evaluated by single factor evaluation model.The source of heavy metals was also investigated by correlation analysis and factor analysis.The results show that the sediment environment is not polluted by the heavy metals but Cu in most of the areas and As in parts are close to ... |
