| 摘 要： | 对陕西关中地区清灌区土壤、粮食、地下水及农田退水中的重金属、含氮化合物等污染物进行了分析研究，结果表明：灌区土壤重金属含量在陕西土壤背景值范围内，主要粮食作物尚未受到污染（除F外），但地下水已受到重金属、含氮化合物的污染。同时，灌区农田退水中三氮含量较高，直接排放渭河水体后，影响了渭河水质。另外还发现灌溉能减低土壤F污染。

| Abstract: | The heavy metal of soil, crop, groundwater in the irrigation district of Guanzhong area, Shanxi province, has been researched. It was found that the heavy metal of soil is still among the background value. In spite of fluoride, seed of crop has not been polluted, but the groundwater has been polluted by heavy metal and nitrides. The water Weihe has been contaminated by high concentration of NH\-3\|N,NO\-3\|N,NO\-2\|N in agricultural drainage and irrigating can decline the F pollution of soil. |
