The concentrations of some nonvolatile halogenated hydrocarbons in surface waters of an industrialized city and its surroundings are given. About 80% of the ballast isomers of hexachlorocyclohexane (alpha, beta and delta BHC) and of DDT and its metabolites are in the range of less than 5 micrograms l-1, whereas ca. 50% of lindane (gamma BHC) were found to be between 5 and 100 micrograms l-1. Starting form the remarks about the differential-diagnostic assessment of environmental concentrations conclusions as to the origin of hexachlorocyclohexane isomers are drawn with the help of their distribution pattern. A high part of the gamma isomer, compared with the ballast isomers means an application (e.g. against mosquitos). This fact may be supported if it coincides with the months typical for such an application. in contrast to this if you have high percentages of alpha, beta and delta hexachlorocyclohexane, it indicates a point source or diffuse inputs of technical BHC. If all four isomers are present on a comparable and very low level this may reflect a remobilization from the sediment.
给出了一个工业化城市及其周边地区地表水一些非挥发性卤代烃的浓度。六氯环己烷（α、β和δ六六六）以及滴滴涕及其代谢物的约80%的压舱物异构体浓度低于5微克/升，而约50%的林丹（γ六六六）浓度在5至100微克/升之间。从关于环境浓度的鉴别诊断评估的论述出发，借助六氯环己烷异构体的分布模式得出其来源的结论。与压舱物异构体相比，γ异构体的高比例意味着其有应用（如用于灭蚊）。如果这与此类应用的典型月份相符，这一事实可能会得到支持。与此相反，如果α、β和δ六氯环己烷的比例较高，则表明存在工业六六六的点源或分散输入。如果所有四种异构体都以相当低的水平存在，则可能反映了沉积物中的再迁移。
