Geochemical indices describing PAHs in vegetation and soil in the outskirt of Xi’an.

The soil samples and vegetable samples were labeled by S and V, respectively. LPAHs/HPAHs, the ratio of the sum of 2- to 3-ring PAHs with low molecular weight to the sum of 4- to 6-ring PAHs with high molecular weight; Phe, phenanthrene; Ant, anthracene; Fla, fluoranthene, Pyr, pyrene; Baa, benzo(a)anthracene; Chr, chrysene; Bgp, benzo(g, h, i)perylene; I1P, indeno(1, 2, 3-c, d)pyrene.

土壤样品与蔬菜样品分别以S、V进行标记。LPAHs/HPAHs指低分子量2~3环多环芳烃（Polycyclic Aromatic Hydrocarbons, PAHs）的总含量与高分子量4~6环PAHs总含量的比值；其中Phe为菲（phenanthrene）、Ant为蒽（anthracene）、Fla为荧蒽（fluoranthene）、Pyr为芘（pyrene）、Baa为苯并(a)蒽（benzo(a)anthracene）、Chr为䓛（chrysene）、Bgp为苯并(g,h,i)苝（benzo(g, h, i)perylene）、I1P为茚并(1,2,3-cd)芘（indeno(1, 2, 3-c, d)pyrene）。本数据集为西安市郊区植被与土壤中多环芳烃的地球化学指标。
