Sulfur dioxide
Sulfur dioxide is a noticeable component in the atmosphere, especially following volcanic eruptions. According to the United States Environmental Protection Agency, the amount of sulfur dioxide released in the U.S. per year was:

Sulfur dioxide is a major air pollutant and has significant impacts upon human healt
what day of the week was may 25 2008 UNANSWERABLE what led to this eruption? It initiated as a series of phreatic blasts from the summit then escalated on May 18, 1980, as a major explosive eruption. how was the climate that time? As May 18 dawned, Mount St. Helens' activity did not show any change from the pattern of the preceding month. The rate of bulge movement, sulfur dioxide emission, and ground temperature readings did not reveal any changes indicating a catastrophic eruption what were the damages incurred? The ash fall created some temporary major problems with transportation, sewage disposal, and water treatment systems. Visibility was greatly decreased during the ash fall, closing many highways and roads. Interstate 90 from Seattle to Spokane was closed for a week and a half. did anyone die? Yes, The ash fall created some temporary major problems with transportation, sewage disposal, and water treatment systems. Visibility was greatly decreased during the ash fall, closing many highways and roads. Interstate 90 from Seattle to Spokane was closed for a week and a half. has this place erupted in later years? Yes, the volcano remains active, with smaller, dome-building eruptions continuing into 2008. you have mentioned about a chemical emission above; what is its usage? The overarching, dominant use of sulfur dioxide is in the production of sulfuric acid.

Sulfur dioxide [SEP] As an air pollutant
This improvement resulted in part from flue-gas desulfurization, a technology that enables SO to be chemically bound in power plants burning sulfur-containing coal or oil. In particular, calcium oxide (lime) reacts with sulfur dioxide to form calcium sulfite: Aerobic oxidation of the CaSO gives CaSO, anhydrite. Most gypsum sold in Europe comes from flue-gas desulfurization.
