Wetlands global sulfur emission

Lower terrestrial and coastal emission estimates combined with the increasing loss in wetlands 165-681. although it may not significantly impact the global sulfur cycle, may be an important consideration in local contributions of natural emissions to acid precipitation. 

Little snlfnr is re-emitted from wetlands into the atmosphere. Table 8.7 gives estimates of global emissions of volatile sulfur compounds from different sources. Total emissions are in the range 98 to 120 Tg (S) year 75 % is anthropogenic, mainly from fossil fnel combustion in the northern hemisphere. The main natural sources are the oceans and volcanoes. Wetlands and soils contribnte less than 3 % of the total emission.
