Methane emitting wetlands are subject to pollutant sulfur deposition from both anthropogenic and volcanogenic sources. Results from a range of studies demonstrate that methane emissions are suppressed by sulfate deposition within the range commonly experienced in regions affected by both anthropogenic and volcanogenic pollution. We report findings from experimental studies and a historical assessment of the effects of a large Icelandic eruption that together with an ongoing literature based data synthesis study (RICHES – Regional Integration of CH4 Emissions Studies), suggest the likely magnitude of the effect of sulfate pollution on CH4 emission while shedding light on the processes responsible for the suppression. While microbial interactions play a key role in the suppression, the effect of sulfur on plants may also be an important variable in determining the extent of suppression.
