The Megalopolis Environmental Commission (CAMe) reported on Sunday that Phase I of the atmospheric environmental contingency due to ozone continues in the Metropolitan Zone of the Valley of Mexico (ZMVM) “in order to protect the health of the population from exposure to levels high levels of contamination.
The agency explained that the Mexico City Air Quality Monitoring System predicted that the weather conditions for Sunday would continue to be unfavorable for ozone dispersion.
The Secretary of the Environment of Mexico City, Marina Robles, assured that the contingency declaration was made based on robust environmental monitoring, but it did not mean a total ban on going out, but rather a recommendation for people to take care of your health.
“The protocols for declaring a contingency are not only reviewed by public officials, the authorities, but also specialists in health, atmosphere, and air quality, which makes it possible to establish the levels at which a contingency is declared,” he stressed.
Jorge Zavala, director of the Institute of Sciences of the Atmosphere and Climate Change of the UNAM, explained that there are weak winds, temperatures above the average for November 12 and zero clouds, factors that gave rise to the stagnation of pollutants and the ozone formation, which in turn will cause poor air quality.
In a press conference, he explained that the forecast is that this condition will remain in the next five days.
It is estimated that on Wednesday, with the arrival of a cold front, a better dispersion of pollutants will be recorded, he added.
Sergio Hernández, air quality director of the Mexico City Environment Secretariat (Sedema), explained that at five in the afternoon on Saturday, November 12, an ozone concentration of 163 parts per billion (ppb) was reached. .
