Of concern for public health officials and biologists are models of air
pollution as a function of environmental characteristics. Using a meta-analysis of
government publications Sokal and Rolf (1995) compiled an interesting dataset which
investigates air pollution (measured as annual mean SO_2 concentration per m^3)
as a function of six environmental variables for 32 cities in the United States.
Whenever the data were available they are based on averages of three years 1969, 1970,
and 1971.
