磁化率是一种非常规的评价土壤重金属污染的方法。利用土壤磁化率法对钢铁厂周围耕作土壤中有效态重金属Cu、Fe、Zn、Mn进行了监测。我们的研究位于一个高污染的地区，小网格密度为250？我在中国。结果表明，低场磁化率与土壤有效铜、有效锌、有效锰呈显著正相关。磁化率与有效铁、土壤有机质、pH值之间没有明显的相关性。频率依赖磁化率>5%表明可能存在超顺磁性颗粒、煤燃烧产生的飞灰。
Magnetic susceptibility is a non-conventional way that can be used for evaluating proxy soil heavy metals pollution. The paper monitors available heavy metals (Cu, Fe, Zn, and Mn) present in cultivated soils around ironsteel plant by soil magnetic susceptibility. Our study was located in an area with high pollution with small grid density of 250?m in China. Results showed that low field magnetic susceptibility was significantly correlated with available Cu, Zn, and Mn. No clear association exists between magnetic susceptibility and available Fe, soil organic matter, pH. Frequency dependent susceptibility >5% suggests the possible presence of super-paramagnetic particles, fly ashes produced during coal combustion.
