A preliminary study on PAHs in the surface sediment samples from Dalian Bay
|
Abstract:
The paper presents the study of PAHs in surface sediment samples collected from Dalian Bay and nearby sea area. Concentrations of PAHs are quantitatively measured and distributing characteristics of these compounds in the area are discussed. The range of PAHs concentrations in the sediments is 32.70-3558.88ng/g,the mean concentration is 1152.08ng/g.It is main for PAHs in surface sediment to be contaminated.The PAH content in the sea area is highest near Dalian harbor, and takes second place in samples collected from the monitoring station near the northeast of Dlian Coal Wharf,and decreases gradually from northwest and northeast to south,showing the characteristics of two pointsource pollutiong.
