摘要:有机氯农药(Organochlorine pesticides, OCPs)曾在全世界被大量使用，即使禁用多年，仍能在各种环境介质中被广泛检出，对生态环境和人体健康存在着潜在的威胁。因此OCPs的环境迁移和归趋一直是该领域的研究热点。树皮是一种天然的被动采样器，能够很好的反映出大气有机物长期的污染程度。本文简要论述了树皮作为被动采样器在大气污染物监测研究中应用的优势，并对OCPs在树皮中的残留浓度、特征及影响其富集的因素进行了探讨，最后特别针对具有手性的OCPs在树皮中的对映体选择性特征进行了评述。

Abstract:Organochlorine pesticides (OCPs) had been widely used around the world. Although their application has been restricted for many decades, they could be still detected in various compartments. Since OCPs have great adverse effects on ecosystem and human health, their transport and fate in the environment are the focus of many studies. Tree bark is a natural passive sampler for atmospheric pollutants. It has been successfully used in many cases for monitoring atmospheric organic contaminants. In this review, the advantages of tree bark in the application of monitoring organic pollutants in the air were briefly listed. Then the concentrations and residue characteristics of OCPs in tree bark, as well as the factors influencing their distributions, were summarized. Furthermore, the enantiomeric signatures of chiral OCPs in tree bark were discussed.
