1 Class Project Report, Spring 2014 E 449/549 Sustainable Air Quality Sustainability Transition of Sulfurous Air Quality 1960-2013 Emissions and Causality Drivers - Lesley Olson Ambient Sulfurous Air Quality - Andrew Martahus Control Measures - Jennifer Elwell Instructor: Rudolf B. Husar Washington University, St. Louis, MO, May 2, 2014

2 Sulfur Trends and Patterns Numerous health effects are associated with high PM2.5 Sulfate makes up a large mass percent of PM2.5 Especially in the Eastern United States Sulfur is anthropogenic dependent Changes in regulations and technology can easily be seen There is a constant background range

3 Trend of PM2.5 and Non-S PM2.5 Mass Avg. PM2.5 Sulfate Avg. PM2.5 – Sulfate Organics, Nitrate, Dust Avg. PM2.5 Mass Avg. PM2.5 Sulfate Avg. PM2.5 – Sulfate Organics, Nitrate, Dust Avg. PM2.5 Mass Conterminous US Eastern US

4 Sulfate Spatial Pattern 2002-20062009-2013

5 Sulfur Wet Deposition 1985-19902003-2008

6 Background Concentration SIME1 TRCR1 TRIN1 CRLA1 KALM1 MOHO1 WHPA1 OLYM1 THSI1

7 Sulfate Concentration Driver

8 Seasonal Sulfate Patterns SeasonalUrban and Rural Summer Urban

9 Regional and Seasonal Sulfate Trends Summer

10 Concentration, Deposition, and Emissions AbsoluteNormalized

11 Carbon Dioxide
