Socioeconomic factors have long been incorporated into environmental research to examine the effects of human
dimensions on coastal natural resources. Boyce (1994) proposed that inequality is a cause of environmental
degradation and the Environmental Kuznets Curve is a proposed relationship that income or GDP per capita is
related with initial increases in pollution followed by subsequent decreases (Torras and Boyce, 1998). To further
examine this relationship within the CAMA counties, the emission of sulfur dioxide and nitrogen oxides, as
measured by the EPA in terms of tons emitted, the Gini Coefficient, and income per capita were examined for the
year of 1999. A quadratic regression was utilized and the results did not indicate that inequality, as measured by the
Gini Coefficient, was significantly related to the level of criteria air pollutants within each county. Additionally, the results did not indicate the existence of the Environmental Kuznets Curve. Further analysis of spatial autocorrelation using ArcMap 9.2, found a high level of spatial autocorrelation among pollution emissions indicating that relation to other counties may be more important to the level of sulfur dioxide and nitrogen oxide emissions than income per capita and inequality. Lastly, the paper concludes that further Environmental Kuznets Curve and income inequality analyses in regards to air pollutant levels incorporate spatial patterns as well as other explanatory variables.
