Characteristics and Sources of Polycyclic Aromatic Hydrocarbons in Surface Soil from Chemical Industrial Areas
化工区土壤中多环芳烃的污染特征及其来源分析

Concentrations and composition of 16 polycyclic aromatic hydrocarbons (PAHs) listed for prior control by US EPA were detected by analyzing 28 surface soil samples from the chemical industrial areas of Tianjin Binhai New Area with a gas chromatography equipped with mass spectrometry(GC/MS).Relative concentrations of PAH compounds with different benzene rings and principal component analysis were used to identify the possible sources of soil PAHs.The maximum PAH concentration in all the samples was(5?991.7)(n...
