This study is to measure the concentrations of polycyclic aromatic hydrocarbons (PAHs) and polybrominated diphenyl ethers (PBDEs) in the sediments of the coastal areas along the southwestern Taiwan. Sediment samples were collected and analyzed to investigate the possible sources and characteristics. The concentration of PAHs and PBDEs ranged from 15 to 907 and from N.D. to 92 ng/g dry wt, respectively, and congener compositions for PBDEs were dominated by BDE-209 (68.8-77.9%). Total PAH concentrations we found in coastal sediments were lower than those of other studies in the world. The highest £UPAH values were observed at Kaohsiung coastal areas, while the lowest £UPAH values were found at Tainan coastal areas. Total PBDE concentrations in coastal sediments were lower than those in river sediments. Sources of PBDEs in those sediments from coastal areas were different from those of river sediments because compound compositions in both areas were different. Both total PAH and total PBDE concentrations were significantly correlated with total organic carbon (TOC) and mean particle size (r=0.51, -0.42, p<0.01; r=0.80, -0.85, p<0.01). In comparison with sediment quality guidelines (SQGs), the PAH concentrations of all sediment samples were lower than those outlined in the criteria, that suggests no evident adverse biological effects caused by PAHs. According to the results of hierarchical cluster analysis (HCA) and principal component analysis (PCA), the stations can be clustered into three groups. In general, PAHs in sediments of Kaohsiung coastal area were mainly contributed from combustion sources, while those in Kao-ping estuary were mainly from petrogenic sources. However, both sediments in Tainan and Hsinda harbor coastal areas were mainly contributed from biogenic sources.
