| 摘 要： | 利用2014年秋季珠江口大万山海域大气气溶胶样品,分析了总悬浮颗粒物中微量元素(Cu、Pb、Zn、Cd、Fe、Cr和As)的含量,根据调查结果,利用富集系数法对微量元素的来源进行了分析。结果表明,Cu、Pb、Zn、Cd、Fe、Cr、As来源环境具有相同或相似性。调查海域大气颗粒物中的Pb、Zn、Cd和As含量相对于地壳均表现为强富集,富集系数远远大于10,属于污染元素,主要来自人类活动污染。珠江口大万山海域、辽东湾海域、青岛海域和东海海域这四个海域海洋大气中Pb、Zn和Cu的富集系数依次降低的顺序是一致的。整体而言,珠江口大万山海域Pb、Zn和Cu元素的富集因子相较国内其它海域低,但Cd的富集因子较高,达1000以上,受人类活动影响很大。

| Abstract: | Atmospheric aerosol collected over the Pearl River Estuary in autumn, 2014 was analyzed in order to find air pollution feature in the Pearl River Estuary. Enrichment factor was used to find out the source apportionment of aerosol elements. The results showed that the elements including Pb, Zn, Cd and As were highly concentrated in comparison with crustal and seawater;and these elements were mainly from the pollutants of human activities. Cd had the highest enrichment factor (more than 1,000) in the Pearl River Estuary, which was higher than that found in Qingdao. The area was significantly polluted by man-made air pollutions. |
