The Environmental Commission of the Megalopolis reported that the environmental contingency in the Valley of Mexico continues because high levels of pollution have not decreased. According to the report at 3:00 PM on February 27, the air quality monitoring system of Mexico City indicated that the presence of a high-pressure system over the central region of the country is causing atmospheric stability and weak winds in the Valley of Mexico, which favors the formation and accumulation of ozone, forecasting air quality ranging from Poor to Very Poor due to this pollutant.
These meteorological conditions favor the stagnation of pollutants and the generation of ozone, resulting in poor air quality. Phase I of the environmental contingency aims to reduce the population's exposure to polluted air, decrease health risks, and limit the emission of pollutants.
The population has been urged by CAME to stay informed about air quality and follow health protection recommendations, especially for more vulnerable groups such as children, the elderly, pregnant women, and people with respiratory or cardiovascular diseases. Among the main recommendations are avoiding outdoor activities between 1:00 PM and 7:00 PM, suspending events organized by public or private institutions during that timeframe, postponing sports, cultural activities, or mass events, and avoiding smoking in enclosed spaces.
The importance of following these measures lies in protecting the health of the population and contributing to the improvement of air quality in the region.
