Wetlands are often referred to as the “kidneys of the landscape”, acting as biogeochemical and ecohydrological filters that remove natural and anthropogenic pollutants from groundwater and surface waters alike. Pollutants, such as toxic metals and metalloids (e.g., lead, mercury, arsenic), hydrocarbons (e.g., heating oil, gasoline), or emerging contaminants (e.g., microplastics, forever chemicals, pharmaceuticals), often accumulate in wetlands, resulting in elevated pollutant levels relative to mineral soil ecosystems. While at lower concentrations, such pollutants are often tolerated in wetlands but can lead to increased bioaccumulation (e.g., methylmercury), higher levels can degrade the peatland processes that underpin critical wetland functions, such as carbon cycling, water flow, or vegetation communities. These changes can not only impact the wetland itself, but also the wider natural and anthropogenic landscape the wetlands are situated within. Moreover, disturbances, like wildfire or drought, can remobilize these stored pollutants to downstream ecosystems, potentially leading to environmental and human health issues decades (or even centuries) after the pollution was initially released. We invite topics on the wide range of wetland pollutants that span local to global scales and short- to long-term temporal dynamics; and their impacts on wetland and landscape biogeochemical, hydrological, microbial, and/or biological processes using a range of laboratory, field, remote sensing, or numerical modelling techniques. Additionally, we are keen on topics that highlight the integrated impact of wetland pollutants between disciplines and/or their intersection with policy or human-wildland interfaces (e.g., water treatment, resource development). Furthermore, topics that highlight pollutant mitigation strategies and wetland restoration are welcome.
