ABSTRACT

 

The presence of volatile organic compounds (VOC) in and around a petrochemical industry, located at Ranipet in Tamil Nadu (India), was investigated during the year 2007 by collecting air samples at 4 sites. The air samples were collected in Tedlar bags and charcoal traps and analyzed by GC-MS and GC-FID methods respectively. Analysis of air samples collected in tedlar bags by GC-MS method revealed presence of 19 VOCs and the highest concentration of total VOC in the industry was 10, 635 μg/m3, which was observed at Process area of the industry. The concentration of total hydrocarbon groups contributed an average of 70.1% alkanes, 13.3% alkenes, 7.2% ketones, 4.4% alcohols 4.4% sulfides and 0.59% aromatics for samples collected inside the industrial premises. Alkanes such as, 3, 6-dimethyl decane, 5-methyl undecane and 4-methyl octane were present in very high concentrations ranging from 1000
