| 摘 要： | 从厦门港海区采集两根沉积柱样，研究有机氯农药六六六（ＨＣＨｓ），滴滴涕（ＤＤＴｓ）和多氯联苯（ＰＣＢｓ）在沉积物中的垂直分布，ＨＣＨｓ，ＤＤＴｓ及ＰＣＢｓ含量用ＧＣ法测定，取自厦门港湾口的１号柱样ＨＣＨｓ，ＤＤＴｓ和ＰＣＢｓ的含量范围分别为０．１２～ ０．３２ｎｇ／ｇ，４．６４～１０．５ｎｇ／ｇ和０．０９～０．４６ｎｇ／ｇ取自厦门西港内湾的５号柱样采分别为０．１７～０．３１ｎｇ／ｇ，３．６５

| Abstract: | Two sediment cores collected from Xiamen Bay were studied on the vertical distributions of organochlorinated pesticides (HCHs and DDTs) and polychlorinated biphenyls (PCBs) in the sediments. The concentrations of HCHs, DDTs and PCBs were determined by gas chromatography (GC). Concentration ranges of HCHs, DDTs and PCBs in No. 1 core, collected at the inlet of Xiamen Bay, were 0. 12-0. 32 ng/g, 4. 64-10. 5ng/g and 0. 09-0. 46ng/g, respectively; those for No. 5 core, collected at the inner of Xiamen Western Bay, were 0.17-0. 31 ng/g , 3. 65-159ng/g and 0. 19-72. 7 ng/g, respectively. The vertical distribution characteristics indicated that the sediment at inlet of Xiamen Bay had not been evidently polluted by these organochlorine compounds, but the inner of Xiamen Western Bay was moderately polluted by PCBs in 1989-1990 and input DDT into the inner of Xiamen Western Bay is still in existence. |
