In this paper we focus on environmental assessment based on the air pollution data measured on carbon monoxide, nitrogen dioxide, sulfur dioxide, ozone and particulate matter from seven monitoring stations in Bangkok Thailand for each season, covering the period 2002-2004 and apply Multiple Criteria Decision Making (MCDM) method and its modification to compute an overall air pollution index for making an overall judgment among these stations. Therefore, comparing and ranking of regions are feasible in terms of air pollution for environmental protection. We also study robustness of these overall indices.
