Even everyday levels of air pollution may insidiously affect health and behavior. Indoor air pollution is a problem in developed countries, where efficient insulation keeps pollutants inside the structure. In less developed nations, the lack of running water and indoor sanitation can encourage respiratory infections. pollution is a worldwide problem and its potential to influence the health of human populations is great (Fereidoun et al, ; Progressive Insurance, ).

This chapter discusses the relationship between economics and air pollution: first, it presents the main characteristics of the economic growth-environmental pressure debate and introduces the concept of environmental Kuznets curve hypothesis (EKC). As an example of the EKC, the estimated relationship between CO2 emissions and economic growth, using a cross-sectional sample of . For an air pollution problem to exist there must be present a source of airborne pollutants and an ad-versely affected population or envi-ronment. Consequently, detailed knowledge of the types and quanti-ties of emissions to the atmosphere is fundamental to an understanding of the nature and magnitude of urban air pollution. The particular degree. ful.
