摘要
[目的]研究台山地区土壤富硒来源,为资源开发利用提供重要科学依据。[方法]从成土母质和大气沉降上,对比分析了硒的含量。[结果]源岩中,上寒武系地层含硒量高,可达1.34 mg/kg;大气干沉降物中,硒年通量平均达285.18μg/(m2.年)。[结论]上寒武统水石组为该区的主要物质来源,而大气沉降为提供丰富物质补充。
[Objective] The source of selenium in soil in Taishan City was studied to provide a scientific basis for resource development.[Method]According to the research of the parent material and atmospheric deposition,the source of soil selenium in Taishan was studied.[Result]The Late Cambrian strata had high contents of selenium in the parent material,reaching 1.34 mg/kg.The dry deposition fluxes of selenium was 285.18 μg /（m2.a）.[Conclusion]The Late Cambrian strata provided a rich source of material for the soil in the area.Atmospheric deposition offered a substance added.
