摘　　要：本文报道了厦门港湾两个站位岩芯沉积物及其间隙水中BHC、DDT的垂直分布,给出了它们在间隙水中的主要存在形式及其含量,初步探讨了BHC在海水、间隙水和岩芯沉积物中的含量分布关系。Vertical distribution of BHC and DDT in the interstitial water of marine sediment cores from two stations in the Xiamen Harbour is reported for the first time. The results show a wavy distribution of BHC composed majorly of α-BHC, γ-BHC and β-BHC and DDT composed majorly of pp'-DDD and pp'-DDT in the interstitial water of sediment cores. The range and average values of BHC and DDT contents in the cores and intestitial water are 2.0—16.6, 5.5μg·BHC/kg, 0.8—13.5, 6.3μg·DDT/kg and 26—511, 212 ng·BHC/L and 9—505, 42.5ng·DDT/L. BHC concentration decreases in the order of sediment core, intestitial water and sea water.
