The present study entails the determination and evaluation of potential risk due to Polycyclic aromatic hydrocarbons (PAH’s) which is one of the known organic pollutants. There is very little information available regarding polycyclic aromatic hydrocarbons (PAHs), a persistent environmental pollutant in Lahore, Pakistan. This research was carried out by collecting atmospheric particulate matter with the help of high volume samplers from December 2013 to December 2014. From literature it was found that greater levels of PAH concentration were observed during winters due to changes in emission sources and the climatic effects. The sampling site was one of the busiest and heavy traffic areas named Yadgar Chowk, Lahore. PAH’s quantified with the help of Gas Chromatography. The average total concentration of PAH was found to be 239 ngm-3. Among the determined polycyclic aromatic hydrocarbons Benzo (a) Anthracene (BaA) was found to be in highest concentration i.e. 58 ngm-3.
