    陕西关中富硒土壤区农作物重金属含量相关性及安全性评价

    Correlation and Safety Evaluation of Crop Heavy Metal Content in Shaanxi Guanzhong Selenium-enriched Areas

    • 摘要: 为了研究关中富Se土壤区不同农作物与土壤中重金属元素间的相关关系和土壤环境的安全性,选择关中三原—阎良、户县等富Se土壤区不同农作物和根系土壤开展研究,采集小麦、油菜、甘蓝等各类农作物样品及根系土样品,分析重金属元素含量,并进行植物重金属含量相关性分析和土壤安全性评价,得出以下结论:不同种属农作物对各重金属表现为不同的富集特征。油菜对重金属表现出较强的富集性,而番茄、辣椒等表现为不富集特征;关中富硒区土壤十分清洁,未受到重金属的污染,满足无公害农产品和果品基地建设的要求。该研究成果将为大力开发关中富Se土壤资源提供地球化学依据。

       

      Abstract: In order to study the correlation between different crops and heavy metal elements in the soil and the safety of the soil environment in Guanzhong soilselenium-enrichedareas,the authors selected some different crops i.e.wheat, rapeseed, cabbage, etcand root soils from the selenium-enriched areas of Guanzhong Sanyuan-Yanliang and Huxian for analysis.Through analyzing heavy metal element content in crops and the soil safety,it is concluded that different species of crops have different enrichment characteristics for different heavy metals.Rape shows strong enrichment for heavy metals, while tomatoes and peppers show no enrichment characteristics.The non-polluting soil in Guanzhong selenium-rich areas meets the requirements of the pollution-free agricultural bases.The resultsprovides geochemical references for the development of Guanzhongselenium-enriched soil resources.
