This book reviews the current study of air pollution and its impact of health on different income groups in one of the developing countries, India. The study estimates the industrial emissions of CO2, SO2 and NOX in India during 1983-84 to 1998-99. To evaluate the health impacts of the pollution on different income groups the study also carries a micro analysis for a metro city, Calcutta. The micro analysis evaluates the extent of deterioration in air quality, identifies the factors responsible for deterioration, and finally makes an assessment of the impacts of deteriorated air quality like effects on human health of different income groups. One of the biggest tasks at present, the book concludes, is to tackle the generation of emission by the higher income groups along with the improvements of the health scene of the economy. It calls for proper policy for the mitigation of the air pollution generation from the experience of other countries.
