摘要：
The distributions of 16 polycyclic aromatic hydrocarbons (PAHs) were determined in the aqueous phase, suspended particulate matter (SPM), sediment, and pore water of the Daliao River Estuary in Liaodong Bay, Bohai Sea (China). Total PAH concentrations ranged from 139.16 to 1717.87 ng L-1 in surface water, from 226.57 to 1404.85 ng L-1 dry weight in SPM, from 276.26 to 1606.89 ng g(-1) dry weight in sediments, and from 10.20 to 47.27 mu g L-1 in pore water. PAH concentrations were at relatively moderate levels in water, SPM, sediment and pore water in comparison with those reported for other estuary and marine systems around the world. Sedimentary PAH concentrations decreased offshore owing to active deposition of laterally-transported river-borne particles. PCA analysis of the possible PAH source suggested petrogenic and pyrolytic PAH inputs in the studied region. (C) 2009 Elsevier Ltd. All rights reserved.
