  1. CHEM 304 – 3/5/12 I.C. Tropospheric chemistry: - Overview / Synopsis Observations: The Clean Air Act READ Ch.3, Ch.5, appendix on orgo. Chem. QUIZ TODAY!

  2. NOx Emissions

  3. SOx Emissions

  4. Sulfur Content of Coal (%)

  5. pH of Precipitation

  6. Policy: I) The Clean Air Act 1963 —> 1990 (Current Law) SOx: 2 million tons/yr by 2012 NOx: 1.25 million tons/yr by 2010 Hg: 5 tons/yr. by 2008 II) The “Clear Skies” Initiative (2 steps) —> Proposed 2003 SOx: 4.5 million tons/yr by 2010 (3 by 2018) NOx: 2.1 million tons/yr by 2008 (1.7 by 2018) Hg: 26 tons/yr. by 2010 (15 tons/yr. by 2018) (Source: NRDC web site… But I have see this elsewhere..)

  7. Sulfate Deposition: then and now

  8. pH of Precipitation

  9. pH of Precipitation

  10. The National Atmospheric Deposition program: http://nadp.sws.uiuc.edu/ http://nadp.sws.uiuc.edu/data/animaps.aspx (animations index) http://nadp.sws.uiuc.edu/data/amaps/so4/amaps.html (an awesome animation)
