The work investigates the concentration of the pollutants PM 10, PM 2.5, SOx, and NOx from various sources like automobiles, oil refinery etc in and around the Kaziranga National park. 3 sampling sites were selected including 1 industrial(InT), 1 residential(TS) within the refinery 1 roadside(BP) within the kaziranga national park area. At each site all 4 pollutants were monitored twice a week and eight times in a month using PM 2.5/10 sampler for particulates and High volume Sampler with gaseous attachment for SO2 and NO2 during the year June 2013 to May 2014. The values of all these pollutants (particulates and gaseous) are observed to be very much below according to National Ambient Air Quality Standards. However the area is mostly covered with forest reserve
