    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.
