Natural and anthropogenic sources of sulphur compoundsNatural: Marine phytoplankton produce dimethyl sulfide (DMS) which is then oxidized to SO2 in the atmosphere Decay processes in soil and vegetation produce H2S (as one of sulfur compounds) SO2 is emitted into the atmosphere by volcanoes.Most recently, however, the natural sources have been by far surpassed by anthropogenic sources. Natural sources have been estimated to produce around 24% of all sulfur dioxideemissions, whereas human-caused emissions made up around 76%.Anthropogenic: Fossil fuel combustion accounts for almost all anthropogenic (human-caused) sulfur emissions. Historically, the use of coal in domestic heating was a major source of sulfur dioxide emissions, but has recently declined.- Energy Productiono Electric power generationo Petroleum refiningo Other combustion- Commercial and residential use- Combustion for industry use- Production processes- Extraction and distribution of fossil fuels- Transporto Road transporto Other Transport (such as aviation, ships,
