Beside particulate (ash and other particles), volcanoes can release enormous quantities of gases, including the following pollutants:
H2O water vapor
CO2 carbon dioxide
SO2 sulfur dioxide
H2S hydrogen sulfide
CO carbon monoxide
HCl hydrogen chloride
HF hydrogen flouride
Even non-explosive basaltic volcanoes (Hawaii, Iceland) can release damaging quantities of pollutants in the form of "vog
