(katu.com) Mount St. Helens Is Washington State's New Top Polluter

SEATTLE - Washington state's top polluter is not a pulp mill, a power plant or refinery, it is actually the newly awakened Mount Saint Helens.

Since the volcano began erupting in early October, it has been pumping out 50 to 250 tons a day of sulfur dioxide, the lung-stinging gas that causes acid rain and contributes to haze.

At peak, that's more than double the amount from all the state's industries combined.
