导言。泥炭地存在了数千年,是全球重要的大气二氧化碳汇(2012年6月)和区域重要的污染物汇,如铅、砷或汞(有毒金属和类金属,TMM)(Bindler 2006)。泥炭地在大气碳封存中的作用常常盖过它们在储存污染物方面的作用,尽管例如,泥炭汞的累积速率比工业化前的速率增加了60-130倍(Bindler 2006)。泥炭地通过一系列生态水文反馈和植物特征维持其碳和TMM汇的持久性(Souter和Watmough 2016,McCarter等人2020)。然而,气候变化、土地利用变化和野火的相互作用正在测试泥炭地的复原力(Wilkinson等人,2023),可能会将其新的和遗留的碳和TMM的长期储存置于灾难性释放的边缘。
Introduction. Peatlands have persisted for millennia, acting as globally-important sinks of atmospheric carbon dioxide (Yu 2012) and regionally-important role sinks of pollutants, such as lead, arsenic, or mercury (toxic metals and metalloids, TMMs)(Bindler 2006). The role peatlands play in atmospheric carbon sequestration often overshadows their role in storing pollutants despite, for example, peat mercury accumulation rates increasing 60–130× relative to pre-industrial rates (Bindler 2006). Peatlands sustain their carbon and TMM sink persistence through a suite of ecohydrological feedbacks and plant traits (Souter and Watmough 2016, McCarter et al 2020). However, the interaction of climate change, land-use change and wildfire are testing peatland resilience (Wilkinson et al 2023), potentially placing their longterm stores of recent and legacy carbon and TMMs on the edge of catastrophic release.
