Abstract:
Polycyclic aromatic hydrocarbons(PAHs) in soil have serious latent danger to our human health. Based on the sampling data, the spatial scale-dependent correlations of PAHs content and some soil properties are analyzed by Factorial Kriging for top soil in Tianjin area. Based on 1 88 topsoil samples in Tianjin area, pH, TOC, CLAY and sum of 16prior PAHs are tested. Resultsshow that significant difference on spatial correlations at different spatial scales between the PAHs content and soil properties such as pH, TOC and CLAY existed in the studies area.
