Acid gas hazards in the crater of Villarrica volcano (Chile)
The atmospheric concentrations of the acid gases SO2, HCl, and HF were measured during austral summer 2001 in the summit crater area of Villarrica volcano using 'filter packs'. These data were collected in order to assess the acid gas hazards to tourists who ascend the volcano. The authors compared their acid gas concentration results with exposure limits outlined by the National Institute of Occupational Safety and Health (NIOSH-United States of America). The authors conclude that tourists who visit the summit crater of Villarrica may be exposed to non-lethal concentrations of SO2 and HCl that exceed the recommended exposure limits defined by NIOSH, while atmospheric concentrations of HF do not exceed the recommended exposure limits
