摘要

The Monterrey Metropolitan Area (MMA) is the third largest urban area in Mexico. Its population is around 4 million and the vehicle fleet around 1.6 million, being the metropolitan zone with more vehicles per capita in Mexico. Industry, commerce and population are increasing fast in the MMA. Traffic activities are saturating the city and the introduction of used vehicles from the U.S. will increase the fleet and may have an important contribution in emissions. The emission inventory of the MMA has not been actualized since 1995 and only an aggregated emission inventory by municipality was published in 1999. In this work we present and discuss the results of the 2005 mobile source emission inventory. The MMA vehicle fleet was classified in accordance with the Mobile6.2 Mexico model. This is the most recent model developed for use in Mexico to estimate mobile source emissions. The results of the study show that about 14% of vehicles are from 1981 and before, 51% are in the range 1982-1999, and only 35 % are models 2000 to 2006. The 2006 models considered were sold at the end of 2005. We calculated emissions of CO, NO, SO_2, VOCs, PM_(10,) PM_(2.5), NH_3 and CO_2. The results show that more than 6.3 millions of tons of CO2 were emitted and 0.58 million tons of the other pollutants (84.5% of CO, 9.6% of VOCs, 5.45% of NO and the rest of the other pollutants). Private vehicles (sedans and SUVs) contribute with 63.9% of the emissions and public transportation vehicles (taxis and buses) with 20.9%. Important findings are that vehicles 1987 and before contribute with 60% of the CO emissions and with almost 70% VOCs emissions. We estimate that the introduction of 300 thousand used vehicles may have an impact on emissions in the order of 12.7%.
