The authors report a study of the atmospheric release of gases from Mount Erebus, in continental Antarctica, over the period Dec 1986 to Jan 1991. This provides a case study of gas releases in a region of the planet almost devoid of anthropogenic sources. The discharge rates of chlorine, fluorine, and sulfur compounds have been monitored. The emission rates of HF and HCl were observed to double over this period to levels of 6 and 13.3 Gg/yr. Measurements were made from filter paper samples, relative to SO[sub 2] emission rates measured independently of the filter samples.
