College of Reso rce and Environmental Science, Lanzho University, Lanzho 730000, China Abstract: Sim ltaneo s meas rements of non-methane hydrocarbons ( NMHCs) in the ambient atmosphere in Beijing and Tianjin cities were performed from A g st 15 to September 15, 2006. The maxim m increment reactivity ( MIR ) was sed to eval ate the ozone prod ction 3 potential of NMHCs. The average ( NMHCs) in Beijing City was 780 gm higher than that in Tianjin City. The ozone prod ction potential 3 3 of NMHCs was calc lated by ( NMHCs) in the morning, at 1 470 gm O in Beijing City and 814 gm O in Tianjin City, respectively. 3 3 Aromatics have most contrib tionsto the ozone prod ction, acco nting for 75% and 73% respectively in Beijing andTianjin cities, followed by alk
