Analysis of Heavy Metal Content in Food Crops Planted Along the Shaanxi Inner Mongolia Expressway

AI Hai-jian et al(School of Life Science,Yulin College,Yulin,Shaanxi 719000)  
To understand the effect of the running of Shaanxi Inner Mongolia Expressway on food crops planted along the sides,we determined the heavy metal contents(Zn,Pb,Cu and Cb) in the digestion solutions of the root,stem and leaf from rice and corn.The results showed that highway promoted the accumulation of heavy metal elements in corn and rice.Compared with the CKs(crops produced where no highway extend),contents of heavy metal elements in two crops tested from two sampling sites were both over standard.This indicates that food crops planted within 100 m away from the highway are been polluted by heavy metals,which is directly related with the running of Shaanxi Inner Mongolia Expressway.Based on this,the areas within 100 m away from the highway are not suggested to cultivate food crops.
