摘要：Environmental pollution is an ever-increasing problem in the industrialized and highly populated areas of theworld. Recently the intensity and magnitude of air pollutant concentration has grown up rapidly in thetroposphere. Hyderabad, capital of Andhra Pradesh, is a centre of southern part of India for both industrialand commercial activity. It is one of the most populous urban areas with approximately 6.8 million inhabitantsand over 73,000 small, medium and major industrial establishments sharing the greater city. The air pollutionis primarily associated with automobiles and industrial sources of which motor vehicles are of major concern.The available information on the levels of ambient gaseous pollutants in tropical areas particularly Asiancountries were meagre and keeping in the view of health effects and economic burden associated with theelevated levels of air pollutants, the present study was undertaken with an objective to assess the ambient airquality of Hyderabad which is undergoing rapidly urban and industrial development. For this study, the airsamples were drawn at the height of 1.5-3.0 m from the ground level in order to monitor the PM, SPM, oxidesof nitrogen and sulphur concentrations to ascertain the relationship between gaseous air pollutants andmeteorological parameters. The overall result reveals that the air quality of environment is deterioratingrapidly due to gaseous pollutants. This study lead us to conclude that multiple approach is needed to combatthe air pollution by vehicles via public awareness campaigns, media intervention packages, effectivegovernment action plans and programmes and judicious distribution of quality oriented fuels.
