本文综述了近年来发展起来的铊形态分析方法。它们中的大多数需要物种的转化，并且不允许直接检测感兴趣的物种。优化了LC-MS和IC-ICP-MS方法，用于直接分析淡水中ng L−1水平的铊物种Tl+和（CH 3）2 Tl+（二甲基铊（DMT））。这些方法应用于对斯托尔贝格（德国）维希河水的研究。Tl+至少部分来自人为来源，其中工业来源可能是重要的。DMT的自然发生被证明，虽然这个Tl-物种是随时间变化的丰度和Tl+占主导地位。
This study provides an overview on Tl-speciation methods developed in the last years. Most of them require transformation of a species and do not allow direct detection of the species of interest. LC-MS and IC-ICP-MS methods are optimised for direct analysis of the Tl-species Tl+ and (CH3)2Tl+ (dimethylthallium (DMT)) in freshwater on a ng L−1 level. The methods are applied in a study of water from Vicht River in Stolberg (Germany). Tl+ is shown to be at least in part derived from anthropogenic sources among which the industrial sources may be significant. The natural occurrence of DMT is proven, although this Tl-species is temporally variable in abundance and Tl+ predominates.
