| 摘 要： | 福建省沿海经济带生态地球化学调查,在福建近岸浅海区域共采集479个沉积物样品,分析测试了52种化学元素以及pH值和有机碳等指标。依据《海洋沉积物质量》(GB18668-2002)的标准,对底积物中Cr、Cu、Pb、Zn、Cd、Hg、As等重金属元素进行了环境质量综合评价,结果表明福建省近岸浅海基本为清洁区,约占70.8%;连江以北闽东海域为Cr、Cu超标的轻污染区,约占26.7%;九龙江口—厦门西港海域为Pb、Zn超标的重污染区,约占2.5%。

| Abstract: | During the present study we surveyed the bio-geochemistry in the coastal economic zone in Fujian Province.479 sediment samples were collected,and 52 elements,pH and organic carbon were analyzed.Heavy metals such as Cr,Cu,Pb,Zn,Cd,and Hg in the bottom sedimentary substances were comprehensively estimated in environmental quality,based on the standard of Quality of Marine Sediment(GB18668-2002).The analysis results indicate that coastal sea in Fujian is basically a clear band,accounting for roughly 70.8% of the whole sea area.Sea area north of Lianjiang in the eastern Fujian Province is a zone of mild pollution where Cr and Cu exceed the standard amount.Sea zone in the estuary of Jiulong River and Xigang harbor in Xianmen is heavily polluted where Pb and Zn overrun the standard,accounting for roughly 2.5% in concentration. |
