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.
