Abstract
Polymiclear aromatic hydrocarbons (PAH) including fluoranthene, pyrene, 1,2-benzanthracene, chrysene, 3,4-benzpyrene (1,2-benzpyrene) and 1,12-benzperylene, were identified in sediments from Hirakata Bay. Their concentrations were proved to be in the range from several hundred µg/kg to several mg/kg of dry samples.Significant positive correlations were statistically found between total amount of PAH and Pb, Hg, Cd, Cu, Zn and ignition loss in bay sediment. In addition, significant positive correlations were statistically found between ignition loss and the content of clay as well as the sum of (clay+silt) contents for both river and bay sediments.
