Concentrations of environmental pollutants tend to follow positively skewed frequency distributions. Two such density functions are the gamma and lognormal. Minimum variance unbiased estimators of the expected value for both densities are available. The small sample statistical properties of...

This paper investigates the effect of overurbanization on different measures of air pollution in a diverse sample of developed and developing countries. The main finding is that overurbanization increases greenhouse gas emissions, measured by CO2, NOx and SO2 emissions per capita. This effect is...

Schwartz and Hayward offer an alternative analysis of air pollution levels, trends, and prospects in metropolitan areas across the United States.
