| 摘 要： | 2009年,以胶州湾湿地为研究区域,分别于2,5,8,11月进行表层沉积物采集,并对沉积物中HCHs和DDTs含量进行检测。结果表明:潮间带区域表层沉积物中HCHs含量范围:(17.56～77.39)×10-9,DDTs含量范围:(ND～89.87)×10-9;浅海区域表层沉积物中HCHs含量范围:(ND～62.71)×10-9,DDTs含量范围:(ND～73.43)×10-9。各测站沉积物HCHs、DDTs含量变化与胶州湾入湾河流的流量变化相一致。即:丰水期含量偏高,枯水期含量偏低,说明二者主要来源于河流输入和地表径流输入。

| Abstract: | The sediments samples in the shallow sea wetland of Jiaozhou Bay were collected in Feb,May,Aug and Nov,2009.The concentrations of HCHs and DDTs in the sediments were determined.The results showed that:(1)The concentration of HCHs in the surface sediments from tideland area was from 17.56×10-9 to 77.39×10-9,meanwhile DDTs was from undetected to 89.87×10-9.The concentrations of HCHs and DDTs in the surface sediments from shallow sea were from undetected to 62.71×10-9,and from undetected to 73.43×10-9,respectely.(2)It was relatively clear that the concentrations of HCHs and DDTs at each station were changed with seasons,and their changes were as same as the flows’ changes of the rivers which flow into Jiaozhou Bay.They were higher in Aug when the rainfall was plentiful,and were lower in Feb,May and Nov when the rainfall was not enough.(3)The concentration distributions of HCHs and DDTs in sediments in the whole research sea area were relatively scattered and there was not an intensive pollution source,which meant that the research sea area were area polluted. |
