Study on Evaluvation of Benzo (a) Pyrene Soluble Fraction in Respirable Suspended Particulate Matter in Peenya Industrial Area by GCMS

Polycyclic aromatic hydrocarbons (PAHs) were identified to be one of the major toxic air pollutants in urban environment. PAHs are mostly formed during incomplete combustion or pyrolysis of organic material. According to National ambient air quality Indian standard, benzo (a) pyrene (BaP) concentration Particulate matter (PM10) in ambient air in the Peenya industrial area Bangalore metropolitan in India has been determined. Air samples for the analysis of BaP in suspended particles have been collected (as 24 h sample once in a month) at selected monitoring sites within the Peenya industrial monitoring network. In this research work, the results of PM10 were collected between February 2011 and April 2011. The Benzo(a)pyrene concentrations of the eight sampling sites ranged from zero to 0.0490ng/m3. Spatial variations were predominantly due to the different strengths of source emission. The total Benzo(a)pyrene concentrations at Kongovi Monitoring Station site was higher than those at other seven sites during monitoring period, observing the results obtained during the period of a whole year, it was concluded that, the concentrations of BaP were much higher during winter season at almost all measuring sites.
