Abstract:

通过工业污染场地表层土壤的模拟酸雨浸泡试验,分析了不同酸度的模拟酸雨浸泡前后土壤中有机质、EPA优先控制的16种多环芳烃含量和矿物质组成的变化.研究结果表明,酸雨浸泡前后土壤矿物相组成相似,主要以石英为主,只是在矿物组成的量上存在差别,浸泡后土壤中赤铁矿和粘土矿物的含量较浸泡前有所减少.模拟酸雨浸泡后土壤中有机质和多环芳烃均有不同程度的释放,酸雨pH值越小,释放量越大,且多环芳烃可能是随着有机质一起释放的;酸雨对土壤中不同性质多环芳烃释放的影响不同,对低环多环芳烃(环数≤3)释放的影响较大,对高环多环芳烃(环数≥4)影响较小.研究结果为理解在酸雨作用下工业污染场地土壤中多环芳烃的释放规律及土壤中多环芳烃稳定性研究提供一些科学依据.
