Unplanned industrialization and urbanization are causing health hazard mainly in developing countries.

It is essential to assess the magnitude of future hazard in an industrial town.

The geographical information system is a special type of tool evolved to analyse geographic data for efficient planning.

In India large-scale industrialization started after independence.

New industrial towns have been established and Durgapur in West Bengal is one of them.

In this study an indigenously developed GIS package GRAM has been used to assess air quality in Durgapur town.

Using GIS, interpolated maps have been prepared showing the distribution of five pollutants, i.e. carbon monoxide, total oxidant, nitrogen-oxide, sulfur-dioxide and suspended particulate matter.
