白洋淀地区土壤——植物系统中污染物含量与变化规律研究

In this paper, the content and distribution of pollutants in soil plant system typically polluted by irrigating farmland soil are discussed. The results show that some heavy metals accumulate in the soil. So far, it hasn't brought about obvious endanger to plants in farmland and majority of heavy metals accumulate in the roots.
