Abstract:Distribution and behavior of fluoride (F) and cadmium (Cd) in cultivated soil profile from suburban oasis soils in baiyin city irrigated with waster water for a long time was investigated. Results showed that there had the different levels of leaching transport for different elements under the influence of infiltration of irrigation or precipitation, and the order of element transport levels was F>Cd, the migration depth of F reached to 80~100cm, the migration depth of Cd reached to 40~60 cm; the significant model of negative power function were both found for F and Cd to explain the heavy metal transfer in soil profile, while F and Cd showed different migration behavior that F had high mobility with large dose, but Cd exerted opposite effects. As a source of soil pollutants, wastewater irrigation could make difference on accumulation and mobility of F and Cd, and F may pose a threat to groundwater.
