Determination and Quality Evaluation of Soil Heavy Metal Comtent in Grape Base of Beining City

The Content of soil heavy metals was measured in the fields in the Grape Base of Beining City,by using Flame Atomic Absorption Spectroscopy(FAAS).The soil samples were collected from five representative vineyards.The Content of heavy metals was measured,by applying the Single Factor Contaminant Index and the Nemerow Pollution Index.After compared the Natural Background Value to the Environmental Quality Standard for Soils(GB 15618-1995),the high concentration of copper was shown in the results.Nevertheless,no more other heavy metal were found higher than the Standard,so enhanced the base's soil measures up to the Environmental Quality Standard for Soils.Finally,the report analysed the reason of high concentration of copper.
