Highlights • Peatland microbes catalyze oxidation and reduction of arsenic and antimony species. • Microbial As/Sb reduction is crucial for efficient contaminant removal in peatlands. • Temperature strongly affects microbial arsenic and antimon

The HYDRUS wetland module is widely used together with the biokinetic model CWM1 to simulate reactive transport of contaminants in constructed wetlands. However, this approach has not been used previously to simulate processes in peat-based wetlands

Increased metal mining in the Arctic region has caused elevated loads of arsenic (As), antimony (Sb), nickel (Ni), and sulfate (SO42-) to recipient surface or groundwater systems. The need for cost-effective active and passive mine water treatment me

Antimony (Sb) is a common contaminant in natural peatlands used as treatment wetlands for water influenced by metal mining in cold-climate regions. However, while other metalloids such as arsenic have been well studied, little is known about removal
