Mountain Cold-Trapping Effect of OCPs and PCBs in Surface Soils of High-Altitude Areas in Guangdong Province

  • 摘要: 采用梅花布点法采样,气相色谱-电子捕获检测法分析,对广东省两处高海拔地区表层土壤中OCPs(有机氯农药)和PCBs(多氯联苯)进行研究.结果表明,罗浮山表层土壤中w(OCPs)和w(PCBs)分别为3.77~9.51和1.85~4.06 ng/g,最大值分别出现在海拔888和824 m.南岭表层土壤中w(OCPs)和w(PCBs)分别为1.47~2.23和1.15~2.49 ng/g,最大值均出现在海拔1 900 m.在表层土壤中大部分目标化合物的浓度随着海拔的增高而增加,表现出较为明显的高山冷凝结现象,累积规律基本上符合Mountain-POP模型.但由于研究区域与Mountain-POP模型假设区域有地理环境和气象条件的差异,一些化合物的高山冷凝结规律与Mountain-POP模型存在一定差异,该现象应为所研究地区不同的自然环境因素所致.化合物本身的理化性质和研究区域的自然条件因素可影响持久性有机污染物的迁移、累积效果.
