title: [Distribution of polycyclic aromatic hydrocarbon in core sediments of the Bohai Straight].
abstract: Thirteen compounds of PAHs were identified by GC in the core sediments of Bohai Straight (S44 and T4 Stations). The distribution and source identification were studied with the two core sediments. The total concentrations changed from 60.3 ng/g to 2076.5 ng/g. Though the contamination of PAHs in the study area is quite modest, some carcinogenic compounds were detected in most samples. From the indicators such as Pen/Anth and Fluo/Pyr etc. the dominated origin of PAHs in S44 Station is pyrolytic origins. However, in T4 Station, a mixture of pyrolysis and petroleum origin is suggested in this area. The distribution of PAHs in the core sediments also could be a good indicative of the contribution of human activity.
