Characteristics of 23 Species of Weed in Northeast of China Hyperaccumulating PAHs in Contaminated Soils
东北地区23种杂草对多环芳烃超积累特性研究

Pot experiments were conducted to investigate the 23 species of weed accumulation characteristics of phenanthrene,as a representative of polycyclic aromatic hydrocarbons(PAHs),from soil in the northeast of China.The result indicated that among the 23 species,the bioconcentration factors of Taraxacum ohwianum K.,Potentilla aiscolor B.and Chelidonium majus L.were all higher than 1,which were 1.01,4.98,38.24 respectively.The phenanthrene concentrations in roots were 2.83,16.34 and 9.66 mg/kg which were lower t...
