Abstract：
Lindane (γ-hexachlorocyclohexane) and its isomers (HCH) are some of the most common and most easily detected organochlorine pesticides in the environment. The widespread distribution of lindane is due to its use as an insecticide, accompanied by its persistence and bioaccumulation, whereas HCH were disposed of as waste in unmanaged landfills. Unfortunately, certain HCH (especially the most reactive ones: γ- and α-HCH) are harmful to the central nervous system and to reproductive and endocrine systems, therefore development of suitable remediation methods is needed to remove them from contaminated soil and water. This paper provides a short history of the use of lindane and a description of the properties of HCH, as well as their determination methods. The main focus of the paper, however, is a review of oxidative and reductive treatment methods. Although these methods of HCH remediation are popular, there are no review papers summarising their principles, history, advantages and disadvantages. Furthermore, recent advances in the chemical treatment of HCH are discussed and risks concerning these processes are given.
摘要：
林丹（γ-六氯环己烷）及其异构体（HCH）是环境中最常见和最容易检测到的有机氯农药。林丹的广泛分布是由于其用作杀虫剂，伴随着它的持久性和生物蓄积性，而六氯环己烷作为废物处置在无管理的垃圾填埋场。不幸的是,某些六氯环己烷(特别是反应性最强的六氯环己烷:γ-和α-六氯环己烷)对中枢神经系统以及生殖和内分泌系统有害，因此，需要开发合适的修复方法来从污染的土壤和水中去除它们。本文简要介绍了林丹的使用情况,并介绍了六氯环己烷的性质,以及他们的确定方法。论文的主要重点,然而,是氧化和还原处理方法的综述。尽管这些HCH修复方法很受欢迎，没有总结他们原则的评论文件，历史,优点和缺点。此外，讨论了六氯环己烷化学处理的最新进展，并指出了这些过程的风险。
