Abstract
The air pollution in Indian cities is increasing at an alarming rate. Amongst the world's 10, most air polluted cities, 6 are from India [1].The air consists of various pollutants like SO2, NO2, PM10, PM2.5, Ozone, CO etc. But PM2.5 is the most dangerous, adversely affecting human health. Air pollution is the 5th highest cause of deaths in India [2]. The study intends to find the particulate matter (PM) concentration levels (PM10 and PM2.5), in Ahmedabad city. 32 areas including commercial, residential, industrial, sensitive etc., across the city, were selected to measure PM10 and PM2.5 concentration, in the month of December 2013.The study found that, almost 44% of these areas had PM10 levels exceeding the permissible limits and 30% of them exceeded the permissible levels for PM2.5, most of them located in the central part of the city. Moreover, certain areas had highly critical PM levels.
