Tvocs Concentration Status and its Correlation with Ozone Concentration in different seasons at GGU campus, Bilaspur (C.G.) India

Keshari P, Jeet P and Singh SS

It is well documented that Volatile organic compounds (VOCs) are determined to be a risk factor in different environments, with the largest source of its emission being the vehicles. This study represents the temporal variability of Total Volatile Organic Compounds Concentration (TVOC) and Ozone at the different locations of the Guru Ghasidas University, Bilaspur (C.G.) India. Eight locations having different vehicular load in the university campus were selected to generate a database of TVOCs and Ozone concentration in different seasons respectively. The TVOC and Ozone concentration were measured by Phocheck Tiger and Multi Gas Monitor. The obtained data shows that the concentration of TVOC and ozone were found maximum in the summer season and lowest in the winter season at all sites. The site with higher vehicular load (Site-1) record a high concentration of TVOC and Ozone in all the seasons. In contrast, tree cover and vegetation directly reduces the TVOC concentration by lowering the atmospheric temperature and consequently lowers the ozone concentration. The overall data depicts a strong positive significant correlation between TVOC and Ozone. More attention needs to be paid to the places I urban areas where the vehicular load is high, for general welfare of the people, and these sensitive places should be brought under green cover to reduce risk factor caused by TVOCs
