Transition of Sulfurous Air Quality: Emissions & Trends 1960-2013

This project report analyzes the sustainability transition of sulfurous air quality from 1960 to 2013, focusing on emissions and causality drivers. The study delves into the impacts of sulfate on PM2.5 and the associated health effects, with a spotlight on the Eastern United States. It highlights the anthropogenic dependence of sulfur and the regulatory and technological changes influencing air quality. The report also discusses spatial patterns of sulfate, trends in sulfur wet deposition, and background concentration data. The findings reveal seasonal patterns in sulfate concentrations and variations between urban and rural areas, outlining a comprehensive analysis of summer concentration, deposition, and emissions.

  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
