In Xiamen offshore area, sediment polychlorinated biphenyls (PCBs) concentrations ranged from 2.33 to 30.94 ng/g, with an average value of 8.94 ng/g. The in situ organic carbon normalized partition coefficients (log K'(oc)) of the 12 co-polar congeners PCBs between sediments and porewater were from 1.50 to 2.64, and the log K'(oc) decreased with increasing chlorine number. PCB congeners pattern of marine organism were characterized by 5-6 CB chlorinated compounds, and the world health organization total dioxin equivalents of PCBs in organism ranged from 1.45 to 88.26 pg/g lipid.
在厦门近岸海域，底栖沉积物中多氯联苯（PCBs）的浓度范围为 2.33-30.94ng/g，平均值为 8.94ng/g。12 种共平面同系物 PCBs 在沉积物与孔隙水中的有机碳归一化分配系数（log K'（oc））为 1.50-2.64，log K'（oc）随氯原子数的增加而降低。海洋生物中 PCBs 的同系物模式以 5-6 个 CB 氯化化合物为特征，生物体内 PCBs 的世界卫生组织二恶英当量范围为 1.45-88.26pg/g 脂质。
