| Abstract: | By methods of geostatistics, 16 prior PAHs contents in the topsoil of Tianjin Area, as well as the soil properties, were studied. The medium scale spatial autocorrelations were well revealed. The spatial structures of PAHs contents demonstrate significant anisotropy. Transportation via atmosphere and content of soil TOC may be two major environmental factors that influence the spatial structures of PAHs contents in soil. |
