The primary emission sources of fine organic aerosol and PM2.5 in the Monterrey Metropolitan Area (MMA) were studied through the quantification of organic carbon, elemental carbon, and molecular organic markers and chemical mass balance (CMB) modeling. CMB results showed that motor vehicle exhaust was the major source, with an average of 64% of the PM2.5 emissions, following by meat cooking operations (31 %) and vegetative detritus/biomass burning/fuel oil (emissions were the least abundant (5%). A comparison of temporally resolved PM2.5 contributions revealed no significant difference in primary aerosol sources between daytime and nighttime hours; however, a significant difference was found between weekends and weekdays. This is an abstract of a paper presented at the AWMA's 107th Annual Conference & Exhibition (Long Beach, CA 6/24-27/2014).
