VAZQUEZ, Carlos; BERISTAIN, Fernando e AUDELO, Estela. Characterization of the Behavioral Pattern of Suspended Particles in the Valley of Mexico. Inf. tecnol. [online]. 2012, vol.23, n.3, pp.3-10. ISSN 0718-0764. http://dx.doi.org/10.4067/S0718-07642012000300002.
The records of pollution by particles in suspension with diameter smaller than 10 μm (PM10) with concentration greater than 60 μg/m3 (the limit of good quality air) of three monitoring stations in the Metropolitan Zone of Mexico Valley were studied. The study includes the months of February, May, August and November. The study considered information by day, weekends and biweekly pay day, to establish the behavior of the polluting agents It was found that the seasons and the land use have significant influence on the PM10 levels; distinguishing three peaks of contamination events. The Merced station was the most polluted; Thursdays and Fridays are the most contaminated days of the week, and when the biweekly pay day is within the week, the number of contamination events increases. The indices of the nonlinear dynamics and the graphs in the phase space indicate a determinist chaotic behavior.
