研究了从勒克瑙与林丹生产有关的小型工业单位收集的土壤样品中六氯环己烷异构体（α -六氯环己烷、β -六氯环己烷、γ -六氯环己烷和δ六氯环己烷）的浓度。所有四种异构体都在十个位点检测到，分析样品中的六氯环己烷异构体总量从53到99 mg kg（-1）不等。采用聚类分析对土壤站点进行六氯环己烷污染水平分组。低α / γ HCH比值被发现，它们表明最近输入的HCH。为了防止对环境的长期污染，迫切需要对这些污染场地进行现场修复。(c) 2008 Elsevier Ltd.版权所有。
Concentrations of hexachlorocyclohexane isomers (alpha-HCH, beta-HCH, gamma-HCH, and delta-HCH) were studied in soils samples collected from a small scale industrial unit of Lucknow associated with lindane production. All four isomers were detected from ten sites and the total HCH isomers in the analyzed samples varied from 53 to 99 mg kg(-1). Cluster analysis was performed to group the soil sites in terms of their HCH contamination level. Low alpha/gamma HCH ratios were found and they indicate recent input of HCH. There is an urgent need for the on-site remediation of these contaminated sites in order to prevent the long-term environmental pollution. (c) 2008 Elsevier Ltd. All rights reserved.
