Concentrations of Volatile Organic Compound (Styrene) in An Industrial Area of Agra, India

Abstract

Volatile organic compounds (VOCs) are major group of air pollutants which play critical role in atmospheric chemistry. These contribute to toxic oxidants which are harmful to ecosystem, human health and atmosphere. A sampling program was conducted to determine the ambient VOC levels in the city of Agra (Uttar Pradesh). India during daytime and overnight in 2010. Sampling sites were selected at three industrial area of Agra. Samples were analysed for styrene. Concentration of Styrene was determined at different sampling points in the air of Agra to investigate their spatial distributions. The vertical motions of air masses also had a large impact on the variations of the level of VOC. The inter-species ratios exhibit clear seasonal variation indicating deferential reactivity of the VOCs species in different seasons.
