Abstract: The white marbled world heritage monument (about 350 years old) is famous world wide for its beauty and perfection. The Environmentscenario is changing due to industrialisation and urbanisation since 80’s decade. Leading to increase in air pollutants in the atmosphere, lookingin to the matter the Central Pollution Control Board (CPCB) has taken various steps in coordination with different departments for positivechange in environment and to examine the effects of steps taken. CPCB has carried out ambient air quality monitoring at four locations in Agracity since 2002. The pollutants respirable suspended particulate matter (RSPM), suspended particulate matter (SPM), sulphur di oxide (SO2)& oxides of nitrogen (NO2) are being monitored at four locations and analysed. The size of respirable suspended particles is less than 10μ andare generated mainly from dust particles, emission from petrol & diesel engine and industrial emission etc. Suspended particles are of the sizeless than 100μ and are mainly emitted from natural sources, sea salt, soil particles, smoke, fossil fuel and industrial emission. These particlessuspend in the atmosphere for longer duration. Sulphur-dioxide and oxides of nitrogen also reach to the atmosphere by different sources. TheData collected from 2002-2008 shows that there is a decrease in suspended particles along with decrease in non-respirable suspendedparticulate matter (long distance travelling particles), due to which improvement appears in air quality of Agra city. For the detailed study ofpollutants metrological data and mixing height from sodar is also included in the study.
