Mexico City began 2019 with Phase 1 of Regional Atmospheric ContingencyPM10 particles, which was decreed after dawn on January 1, when there were extraordinary emissions generated by fireworks, bonfires and other materials burning.
The Environmental Commission of the Megalopolis (CAME) reported in early January that it had reached a level of contamination that exceeded 157 points according to the Metropolitan Index of Air Quality (IMECA) in the station Villa de las Flores and in the municipality of Coacalco de Berriozábal, in the State of Mexico.
Phase 1 of Contingency was maintained until the morning of January 2, when the contaminants were dispersed. These damaging levels began to improve on Tuesday, January 8, when the first gas station closures began in the capital.
Since then, the maximum value was 111 points per PM10 particle, much lower than the values recorded at the beginning of the year.
The Air Monitoring System (Simat) has registered in recent days improvement in air quality in Mexico City, data that has coincided with the closure of gas stations and the shortage of fuel.
Thus, according to the scores, the capital maintains good conditions today (green circles) or regular (yellow) conditions in practically all its extension.
Only negative values were recorded in the municipality of Chalco, where at 17.00 p.m. on the day the value was 101 points, for PM10 particles, when the maximum to reach a satisfactory level is 100.
In an update issued at 6:00 pm via Simat’s twitter, the authorities informed the population that the values in Chalco had improved to 97 points in the MP10 Index. Despite this, it continues to record the maximum value of contaminated air next to Ecatepec.
Therefore, it is recommended that the inhabitants of Chalco and Ecatepec limit the practice of physical exercise or any other type of outdoor effort, mainly to those people who are especially sensitive to pollution.
This trend in the improvement of air quality is evaluated daily, according to the data provided by Simat.
Capital Civil Protection activated at 6 pm the yellow alert for rains in the municipalities of Iztacalco, Iztapalapa, Venustiano Carranza, Alvaro Obregon, Cuajimalpa, Gustavo A. Madero, Miguel Hidalgo, and Magdalena Contreras.
