Industrial air pollution is of major concern to upcoming Indian cities like Trivandrum and Pune in terms of industrialization and urbanization. Even the urban population is exposed to ambient air pollutants; on the other hand the sub-rurals contribute to the cigarette smoke and kitchen cooking fuels. A quantitative analysis on the mean concentration of SO2, NOX, and SPM in four different industrial zones at Trivandrum and Pune was compared with that of non-exposed to

control regions. These attributes were analyzed on the morbidity pattern of the exposed population for eleven various diseases and its hazardous effects are reported in the present study.
