Se ha visto que sin un sistema de monitoreo ambiental integral y eficiente, que propor­cione datos duros de soporte para un diagnóstico de la situación ambiental, no es posible elaborar nuevas políticas públicas para resolver la problemática que enfrentan las áreas urbanas. En el presente trabajo se revisa la situación actual del sistema de monitoreo ambiental de la Zona Metropolitana de la Ciudad de México desde tres ángulos: climatológico, hidrométrico y de calidad de aire. Asimismo se detectan sus principales avances, limitaciones y otras particularidades y al final se complementa el monitoreo ambiental con la parte social y económica. AbstractIt has been proved that without an efficient, integral environmental monitoring system that provides hard back-up data for a diagnosis of the environmental situation, it is impossible to draw up new public policies to solve the problem faced by urban areas. This paper reviews the current status of environmental monitoring in the Mexico City Metropolitan Zone from three angles: climatological, hydrometric and air quality. It also detects the main progress, limitations and other particularities and at the end, environmental monitoring is complemented by the social and economic part.

Aim: The objective of this work was to determine the behavior of the trajectories of the air plots in two sites (San Mateo Atenco-(SM) and San Lorenzo Tepaltitlán-(SL)), in the atmosphere of the Metropolitan Zone of the Toluca Valley (MZTV). Methodology: In the atmosphere of the MZTV, using HYSPLIT a Backward trajectory direction analysis was performed from June 29 to July 8, 2021, considering for each day the summertime schedules of the center, indicating its Coordinated Universal Time (UTC). An ANOVA analysis (with a significance level of α=0.05) was performed for the concentrations of SM and SL obtained with PIXE, with the objective of seeing the equality of their behavior. Results: The behavior of the direction of the trajectories of the air plots in both sites is similar and the trajectories for the same day are the same in both sites but different on another day; It was determined that during night-day (19 to 12 h of the following day) the behavior is similar and changes during the remaining time, being variable. In general, the origin of the trajectories of the air plots for both sites of the MZTV is predominantly from the southeast, a situation that was confirmed with Wind Roses. Of the ANOVA analysis, the p-value was in all cases greater than the significance level of 0.05, the null hypothesis was accept, and it is possible to conclude that the elemental chemical composition of PM2.5 have equal means in both sites. Conclusion: Among other, it is possible to consider the behavior of meteorological parameters and thus take them into account for sampling studies of criteria pollutants such as PM2.5.

En este artículo se explora una interpretación de los conflictos en torno al espacio en la Zona Metropolitana de la Ciudad de México (ZMCM) con base en los conceptos de orden y de contextos urbanos. Para ello se presenta en primer término un conjunto de formas históricas de producción del espacio urbano que, de acuerdo con los autores, conforman en la actualidad cuatro “ciudades”, es decir, otros tantos contextos urbanos que se diferencian entre sí, entre otras cuestiones, por el tipo de conflictos por el espacio que en cada uno de ellos aparece como dominante. En segundo término se examina el concepto de orden urbano y se propone una línea de interpretación de los conflictos relacionados con el espacio que marcan en la actualidad dicho orden en la metrópoli. Por último se describen e ilustran las dinámicas que caracterizan a cada uno de los cuatro contextos urbanos o “ciudades” a partir de las formas en que se combinan diferentes modalidades de organización del espacio, usos del espacio público y privado y conflictos dominantes por el espacio. AbstractResorting to the concepts of urban order and urban context, this paper explores an interpretation of conflicts concerning the uses and modes of appropriation of urban space in the metropolitan zone of Mexico City. To this end, it firstly characterizes a group of historical forms of urban space production that, according with the authors, have given place to four types of “cities” or urban contexts which are differentiated, among other things, because of the dominant spatial conflicts in each case observed. Then it discusses the concept of urban order and proposes an interpretation line of those spatial conflicts that, at present, shape the metropolitan urban order. Finally, it describes and exemplifies the four urban contexts dynamic, considering the ways in which different modalities of urban space organization, uses of public a private spaces, and dominant space conflicts are combined.

This idea compels the authors, at least, to take a quick look, with limitations by the length of the text, to some of the manifestations of the crisis situation prevailing in the country during the period of imposition of the neoliberal pattern of capital accumulation and to the essential features and the contradictions that it has printed to the great metropolis and national capital. From this outline, in the central part of this work, they analyze the specific characteristics of the social movements and the actions that they have developed in the metropolis, between 2011 and 2018, registered in the Laboratory of Urban Conflicts of the Autonomous Metropolitan University, Unit Xochimilco.

Air pollution is a global environmental problem that affects the population. This work demonstrates the perception of air quality by the population of the urban area of the municipality of Acapulco, Guerrero, Mexico. To meet the objective, a survey of 36 questions was applied to a sample of 382 people living in the main crossing points of vehicles, where there is more traffic and more severe pollutant concentration problems. We decided to apply the grouping method within a radius of 500 m around the selected intersections, where 95% of the respondents are aware that the air they breathe has a certain degree of contamination.
