有机碳含量对土壤剖面中多环芳烃纵向迁移的影响
|
摘要
为探索有机碳含量对土壤剖面中多环芳烃(PAHs)纵向迁移的影响,选取北京地区3条有机碳(TOC)含量明显不同的土壤剖面进行了土柱淋滤实验研究.结果表明,通过30 d(相当于北京地区3年的淋滤水量)的淋滤实验后,不同剖面中PAHs均存在不同程度的迁移现象,但剖面中残留的PAHs仍然主要富集在土柱表层0～30 cm土壤中,且中高环数PAHs的残留率明显高于低环数PAHs.TOC含量与PAHs的残留总量之间具有显著的正相关性,TOC含量越高,PAHs残留量越高.此外,TOC对不同环数PAHs迁移的影响程度存在差别,高环数PAHs受TOC变化的影响高于低环数PAHs.
In order to study the effect of TOC on PAHs vertical migration in soil profiles, soil column leaching experiments were conducted on several soil profiles with different TOC in Beijing. Results showed varying degrees of migration of PAHs in different soil profiles after 30-day leaching(equivalent to the leachate water volume in Beijing for 3 years). Residual PAHs was mainly accumulated at surface soil(0～30 cm) and residual rate of PAHs with higher rings was significantly higher than PAHs with lower rings. It indicated that Σ_(16)PAHs residual concentrations is related to TOC positively. The higher the TOC, the higher residual concentrations of PAHs is. In addition, discrepancies were observed for the effect of TOC on the vertical migration of PAHs with different rings. PAHs with higher rings was more affected by TOC than PAHs with lower rings.
