摘要
土壤中的PAHs对人体健康具有潜在的危害 .在天津采样数据的基础上 ,应用多元地统计学中的因子克立格方法 ,探讨了天津地区表层土壤中PAHs含量和一些土壤性质之间的空间相关性 .在天津地区共采集 188个表层土壤样品 ,测定了 16种PAHs的总含量、土壤 pH值、总有机碳含量和土壤粘粒含量 .研究结果表明 ,天津地区表层土壤中PAHs含量和pH、TOC、粘粒含量之间的空间相关性在不同尺度上有很大差异 .
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 188 topsoil samples in Tianjin area, pH, TOC, CLAY and sum of 16 prior PAHs are tested. Results show 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.
