This document discusses a thesis analyzing the relationship between fine particulate matter (PM2.5) pollution sources and socioeconomic status in North Carolina. It provides background on the environmental justice movement and reviews literature showing low-income and minority communities often face greater environmental health risks. The thesis will use geographic and economic analysis to examine if disadvantaged communities in North Carolina bear a disproportionate burden of PM2.5 pollution from point sources. The research aims to provide insights that can guide more equitable pollution control policies and better health surveillance of at-risk populations.
