One hundred and twenty-two red wines were analysed for their total tin, total mercury and speciation concentrations. Total Sn and Hg concentrations were in average 4.4 ± 7.2 µg/L and 0.22 ± 0.12 µg/L, respectively. Two GC-ICP-MS methods were developed and validated for speciation purposes: one to measure organotin compounds (OTCs) with internal standard correction; the other, to evaluate methylmercury (MeHg+) by isotopic dilution. Methyltins (mainly dimethyltin, but also monomethyltin) were the most abundant OTCs recovered. Methylation seems to occur biotically during the wine making process and not during the bottling time. Therefore, it also seems to be roughly dependent on the geographical origin of the wine. For higher OTCs, monobutyltin was the most regularly found, but dibutyltin and monooctyltin were also detected sometimes. MeHg+ was not recovered in any of the samples investigated, probably due to the low level of Hg. These results suggest that, in terms of these parameters, normal consumption of wine is not a hazard for human health.

ICP-MS和GC-ICP-MS测定的全球红酒样品中的锡和汞及其形态（有机锡化合物和甲基汞）。

分析了一百二十二种红酒的总锡，总汞和物种浓度。总锡和汞的平均浓度分别为4.4±7.2 µg / L和0.22±0.12 µg / L。开发了两种GC-ICP-MS方法并对其进行了验证，以用于物种形成目的：一种方法是通过内标校正来测量有机锡化合物（OTC）；另一种是通过同位素稀释来评估甲基汞（MeHg +）。甲基锡（主要是二甲基锡，但也有单甲基锡）是回收的最丰富的OTC。甲基化似乎是在酿酒过程中以生物方式发生的，而不是在装瓶时发生的。因此，它似乎也大致取决于葡萄酒的地理来源。对于较高的OTC，最常发现单丁基锡，但有时也检测到二丁基锡和单辛基锡。在所研究的任何样品中均未回收到MeHg +，这可能是由于Hg含量较低。这些结果表明，就这些参数而言，正常饮用葡萄酒不会危害人类健康。
