Abstract:This study was under taken to investigate the quality of ambient air in Hyderabad City aimed to determine the levels of air borne pollutants i.e. Particulate Matter (PM10), Sulfur dioxide (SO2), Nitrogen dioxide (NO2), Carbon monoxide (CO), Ozone (O3) and toxic metals at five site of different environmental back drops. GMW PM10 High Volume Air Sampler Volumetric was used to trap PM10 using gravimetric method. Ozone O3 was determined (as per ASTMD). SO2 was determined based on West-Gaeke method (as per ISO 6767). For the determination of mass concentration of NO2, Modified Griess-Saltzman method (as per ISO 6768) was used. CO meter was used for CO measurements. The results showed that all the studied parameters were remained out of compliance with WHO stipulations at all sampling sites. Transport sector is the significant contributor of air quality debacle in the Hyderabad city especially two stroke engines. There is need to encourage local urban dwellers to use bicycle or walk to travel short distances, widening of congested city roads, proper sanitation, strict monitoring fuel adulteration, and regular vehicular inspection. There is an urgent need of efficient public road transport system to reduce dependency on personal vehicles that will bring some improvement in deteriorated ambient air quality in Hyderabad city.
