Air quality at two major heavy traffic roads of Lahore, Pakistan was evaluated. Particulate matter (PM) was monitored for twenty four hours at each sampling sites. The total number of vehicles passing was also noted and correlated with the PM levels. The vehicular congestion as well as meteorological factors had a positive association with the PM levels. PM concentrations were significantly higher than the WHO recommended levels. It is necessary to control emissions from vehicular exhaust to reduce the level of pollutants in the ambient air in urban areas. figures, the total number of registered vehicles in the K1 Particulate matter, CO, vehicular traffic, heavy traffic roads, Lahore, Pakistan PB Pakistan Agricultural Scientists Forum LK https://thejaps.org.pk/AbstractView.aspx?mid=2015-JAPS-658
