Assessment of the concentration, source and composition of polycyclic aromatic hydrocarbon (PAHs), polybrominated diphenyl ethers (PBDEs), organochlorine pesticides (DDTs and HCB) and polychlorobiphenyl (PCBs) were analyzed in the sediment samples of the western coast of Taiwan. The results showed that the propinquity to sources of pollutants was the determining factor for spatial distribution of pollutants. Highest concentration of t-PAHs (332.95 ng/g dw), t-PCBs (4.34 ng/g dw), HCB (0.18 ng/g dw) and t-PBDEs (58.36 ng/g dw) was found in station C although t- DDTs was highest in Station D (2.63 ng/g dw). Highly significant correlation was found between total organic carbons (TOC) and the measured pollutants (with p value
