Sediment cores from the southern South China Sea off the Terengganu coast were analyzed for polycyclic aromatic hydrocarbons (PAH s) and perylene. The concentrations of total 17 PAH (TPAHs) and perylene varied between 5.45-27.7 ng/g and 0.51-7.77 ng/g, respectively. Analyses of variance showed significant differences between the stations, but not in sub-bottom depths at the 0.05 level. The PAH cross plots showed a predominance of pyrogenic over petrogenic PAH s. Principal component analysis (PCA) showed clustered PAH s that are correlated with total organic carbon (TOC), indicating the importance of surface runoff via fluvial transport for contributing these PAH s to the coastal environment of the study area. Overall, the concentrations of PAH s in the study area are considered to be in the low range, not exceeding the 100 ng/g mark.
