Abstract:Concentrations of 16EPA polycyclic aromatic hydrocarbons (PAHs), total organic carbon (TOC) and black carbon (BC) contents were investigated in different size fractions (0.063mm) of sediments from intertidal zone of Bohai Bay. The total PAHs (16-EPA) concentration in different size fractions of all sediments ranged from 714.28to 4869.71ng/g dry weight. The highest total PAHs concentration of Qikou estuary (TS3) sediment was measured in the 0.063mm size fractions. The lowest total PAHs concentrations were measured in the 0.031-0.063mm size fraction for all site sediments. However, TOC-normalized total PAHs concentrations trended to increase with increasing size of sediments. Furthermore, stronger correlations between total PAHs versus BC rather than versus OC (OC=TOC-BC) were found. Therefore, distribution of BC in different size fractions of sediments possibly played a more important role.
