ABSTRACT:
Volatile organic compounds (VOCs) play an important role in the generation of O3 and other reactive chemicals in the atmosphere. Anthropogenic emission of VOCs has greatly increased due to growing consumption of fossil fuels and related activities. The concentration of 12 light, C2-C8 VOCs in ambient air of the most industrialized area, Raipur, was measured. The sampling frequency was once in a week at sites: Raipur, (R. S. University campus), for one year, April, 2006 - March, 2007. For diuranal study per hour samples were collected. Twelve VOCs species i.e. C2H2, C2H4, C2H6, C3H6, C3H8, i-C4H10, n-C4H10, i-C5H12, n-C5H12, C6H6, CH3.C6H5 and CH3.C6H4.CH3 were monitored by technique: gas chromatography equipped with FID and PID detector and the purge and trap probe were used The mass distribution of ?12VOCs at site: Raipur, was ranged 48.7 - 171, µg m-3 with mean value of 102.2 ± 8.6, 135. µg m-3,. Among twelve VOCs, three species: C3H8, C4H10 and C5H12 exhibited the highest mass distribution, and accounted > 55% fraction of the total VOCs.
