摘要: To investigate the trend of selected polycyclic aromatic hydrocarbons (PAHs) partitioning, fifteen pore water samples collected from the sediments of three mangrove wetlands were analyzed, and the partition coefficients and the partition model for the PAHs were determined by the correlation between K-oc and octanol-water partition coefficient (K-ow). The results revealed that the mean K-p values in inner mangrove wetlands were between 143 and 1031 L /Kg; the particulate organic carbon (POC) could strongly adsorb low-ring PAHs; the PAHs partitioning was on a obvious trend transported to particle phase. We suggest that the classic equilibrium model of organic carbon normalized (K-p=-K(oc)f(oc)) may be used to predict the trend of the selected PAHs partitioning. (C) 2014 Elsevier Inc.
