| 摘 要： | 为研究城镇化过程中不同土地利用类型土壤中多环芳烃(PAHs)的纵向迁移特征,在快速进行城镇化建设的沈阳东部地区选择了3种不同土地利用类型(城市用地、耕地及林地)的5个土壤剖面(0～1 m),分析了土壤剖面层中PAHs的残留特征,讨论了影响PAHs纵向分布和迁移的因素以及土壤PAHs的来源.结果表明,5个采样点土壤表层ΣPAHs的含量为:城市1号点513. 19～12 689. 04μg·kg~(-1)、旱田点36. 18～7 196. 10μg·kg~(-1)、水田点70. 92～747. 53μg·kg~(-1)、城市2号点19. 39～636. 47μg·kg~(-1)和林地点4. 79～349. 24μg·kg~(-1). PAHs在城市用地和林地中主要被截留在0～30 cm浅层土壤中,在耕地可以迁移至较深的土壤层;高环数PAHs在浅层土壤层中所占比例较大,深层土壤低环数占比较高;土壤有机质与PAHs分布呈显著正相关,PAHs的理化属性对其迁移能力有一定影响;源解析表明,研究区域的PAHs主要来源于工业活动和交通等燃烧,部分低环数PAHs来自于石油产品输入.
