Mount St. Helens is WA state's No. 1 air polluter

John Patrick Luethe writes "The Seattle Times has run an article on Mount St. Helens' recent massive pollution. The article claims that since the start of the recent volcanic activity starting in early October the volcano has pumped out between 50 and 250 tons of sulfur dioxide each day and has become the states largest polluter."

Bigger. The eruption of Mt. Pinatubo, for instance, launched more stuff into the atmosphere than all human activity during the 19th and 20th centuries combined. It had the effect of reducing ozone levels in the tropics significantly, even creating a 20% reduction in the temperate region of the northern hemisphere.
