摘要
根据在中国除台湾省外约 9.6× 1 0 6km2 范围内采集的 4 0 95个土壤样品中砷的分析结果 ,揭示了中国土壤砷的背景含量和分布特征 ,以及土壤中砷与共生元素和有机质等之间的相关关系 ,并且结合环境因素和砷的地球化学性质 。
On the basis of the analytic result of arsenic in 4 095 soil samples collected from China except Taiwan Province,the background content and distributive feature of arsenic in soil of \{China\} as well as the correlations between arsenic and coexistent elements and organic matter were discovered,and their causes of formation were discussed with macroscopic and microcosmic respects.
