A recent paper by Miszczak et al. (2020) examines metal contamination of mires in Poland and Norway. The authors conclude that lead (Pb) records in ombrotrophic peatlands cannot be used to reconstruct the chronological history of anthropogenic activities due to post-depositional mobility of the metal. We contest this general conclusion which stands in contrast with a significant body of literature demonstrating that Pb is largely immobile in the vast majority of ombrotrophic peatlands. Our aim is to reaffirm the crucial contribution that peat records have made to our knowledge of atmospheric Pb contamination. In addition, we reiterate the necessity of following established protocols to produce reliable records of anthropogenic Pb contamination in environmental archives.
米什扎克等人(2020年)最近发表的一篇论文研究了波兰和挪威泥炭地的金属污染情况。作者得出结论,由于金属的沉积后迁移性,雨养泥炭地中的铅(Pb)记录不能用于重建人为活动的时间历史。我们对这一总体结论提出质疑,该结论与大量文献相悖,这些文献表明,在绝大多数雨养泥炭地中,铅在很大程度上是不移动的。我们的目的是重申泥炭记录对我们了解大气铅污染所做出的关键贡献。此外,我们重申遵循既定方案以在环境档案中生成可靠的人为铅污染记录的必要性。
