Temporal Analysis of PM10 in Metropolitan Monterrey, México
The Monterrey Metropolitan Area (MMA) is the third largest city in México. Few studies have been carried out regarding its air pollution. The aim of this study was to analyze the temporal behavior of PM10 (particulate matter ≤10 μm in aerodynamic diameter). Data reported by the “Sistema Integral de Monitoreo Ambiental” (Integrated Environmental Monitoring System) network from 2006 to 2008 were used. PM10 levels were compared among the stations by year, season, and day of week. A bootstrap technique was used to obtain subsamples to which Student's t test and ANOVA were applied. PM10 levels were high and exceeded the annual limit of 50 μg/m3 set up by the Mexican standard Norma Oficial Mexicana NOM-025-SSA1-1993. These levels could have serious health effects. The southwest zone of MMA had the highest levels of PM10 during the period studied. Winter was the most polluted season, and summer was the least polluted season. Thursday and Friday were the most polluted days, and Sunday was the least polluted day. The hours with the highest levels of PM10 were 8:00 to 10:00 a.m., whereas nighttime hours were the cleanest.
Air pollution in MMA, an important city in México, has seldom been studied. The results reported in this work clearly indicate that PM10 levels are high and that it is necessary to establish actions to reduce them. These actions, such as restricting vehicular traffic or limiting industrial emissions, must consider the temporal variations in PM10.
