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
