摘要
选择有代表性的三县(区)农田对太原市土壤 -作物中As含量及迁移转化规律、污染现状进行了研究。结果表明 ,太原市土壤As含量轻微超标 ,污染程度为北郊>南郊>清徐县。作物中As含量不超标 ,As在土壤和作物中有很好的线性相关性 ,作物对As的富集能力为水稻>小麦>谷子>高粱>玉米。
The relationship of arsenic contents between crops and soils in Taiyuan agriculture area was studied by statistical methods. The results indicated that arsenic was a slight pollution in soils and little pollution in crops. In addition, correlation between the element contents in crops and those in soils was significantly observed, and different crops had a different assimilation rates with order: rice>wheat>grain>sorghum>maize.
