摘要
通过对经济发达的韩江三角洲南部地区115个农业土壤样品中氟化物的分析测试,初步摸清了该地区农业土壤氟含量状况。结果显示,46%土壤样品氟含量超过国家平均水平,土壤氟最高含量可达983mgkg-1,而最低仅为125mgkg-1,相差近8倍,各区(县)土壤氟含量分布不均匀。研究区内土壤高氟含量的形成与当地的三角洲冲积形成过程有直接关系,后期人类活动造成的氟污染也对该区域土壤高氟含量有一定的贡献。进一步分析表明,当地地方性氟病与土壤高氟含量存在直接联系。文中还对研究区土壤氟含量与国内部分地区进行了对比分析。
In order to assess Fluorine content in soil of south Hanjiang delta, a survey was carried out. Fluorine contents were detected in 115 soil samples. The results showed that the Fluorine contents in 46% soil samples were up the average level in China. The maximum content and the minimum content were 983mg kg^-1 and 125mg kg^-1 respectively. The reason of high content of Fluorine could be connected with the alluvial process of the Hanjiang delta. Human activities also had some relations with Fluorine content in soil.
