Distribution of Polycyclic Aromatic Hydrocarbons in Soil Profiles in Southeast Suburb of Beijing Wastewater Irrigation Area
北京东南郊污灌区PAHs垂向分布规律

3 borehole profiles samples were collected using Eijkelkamp soil sampler from the wastewater irrigation area of Beijing Southeast suburb.The soil samples were collected from surface to 5.5 m underground every 0.5 m.Physical-chemical properties of the samples such as clay content,total amount of clay minerals,cation exchange capacity(CEC),total organic compounds(TOC),etc.were analyzed.16 polycyclic aromatic hydrocarbons(PAHs) defined by the U.S.EPA were also analyzed with gas chromatography-mass spectrometry...
