ABSTRACT
Volatile Organic Compounds (VOCs) in presence of sunlight and oxides of nitrogen in atmosphere are considered as precursors for ozone production at the ground level. Concentration of Benzene, Toluene and Xylene (BTX) in ambient air was measured near seven traffic junctions in the city of Nagpur. Air samples were collected using Organic Vapour Sampler and analyzed by Gas Chromatograph equipped with Flame Ionization Detector (FID). Benzene concentration was found to be in the range 9.3 to 28.7 microg/m3, Toluene 3.26 to 21.0 microg/m3 and Xylene 4.9 to 15.0 microg/m3. These values are lower than those found in Metropolitan cities like Mumbai.
