【摘要】 持久性有机污染物(persistent organic pollutants, POPs)因其高毒、持久、生物积累、远距离迁移的特性而广受关注.森林土壤含有丰富的有机质,是POPs天然的储存库,对POPs的全球迁移与分配产生重要影响.森林土壤中POPs来源途径不仅包括POPs的干湿沉降,还存在着POPs随落叶迁移至森林土壤的特征途径.森林土壤富集大量POPs,有必要对其在土壤中的环境行为及其环境影响进行总结,因此本文从土-气交换、储存和迁移、降解转化等方面对POPs在森林土壤中的典型环境行为进行综述,分析其对森林土壤根际环境、微生物和微型动物以及食物链传递的环境影响,最后对森林土壤中POPs未来研究方向提出几点建议.更多还原

【Abstract】 Much attention has been paid to persistent organic pollutants(POPs) due to their characteristics of high toxicity, persistence, bioaccumulation and long-distance migration. The forest soils are a natural reservoir for POPs, which have an important impact on the global migration and distribution of POPs. The source of POPs in forest soils include not only the dry and wet deposition, but also the migration along with defoliation. It is necessary to summarize the environmental behaviors of POPs in forest soil and their environmental impact due to a large amount of POPs enriched in forest soil. Therefore, this work summarizes the typical environmental behaviors of POPs in forest soil, including the soil-air exchange, storage and migration, degradation and transformation. And the environmental impacts of POPs behaviors were also analyzed on the rhizosphere environment, microbes, micro-animals and food chain transfer in forest soils. Finally, several suggestions are proposed for the future research of POPs in forest soils.更多还原
