The Megalopolis Environmental Commission (Came) activated the Phase 1 of atmospheric environmental contingency due to ozone in the Metropolitan Zone of the Valley of Mexico (ZMVM), after recording high levels of contamination that represent a significant risk to public health.
The CAMe reported that at 2:00 p.m. maximum ozone concentrations of 158, 157 and 155 ppb were recorded in the monitoring stations located in the municipalities of Benito Juárez, Coyoacán and Álvaro Obregón, respectively.
These levels exceed established limits and require the activation of emergency protocols to protect the population.
The environmental contingency due to ozone in the Metropolitan Area of the Valley of Mexico is due to the influence of a high pressure system in the central region of the country.
This system has generated conditions of atmospheric stability, clear to partly cloudy skies, intense solar radiation and temperatures above 30°C.
These conditions promote the formation of ozone and, due to the weak winds within the Valley of Mexico, facilitate its accumulation in several areas.
Environmental contingency
The activation of Phase 1 of the environmental contingency due to ozone in the Metropolitan Area of the Valley of Mexico aims to reduce the population’s exposure to contaminated air and minimize health risks.
Came has established a series of measures to reduce the generation of pollutants and prevent ozone concentrations from reaching dangerous levels again.
Among the recommended measures are:
Reduce car use: The population is suggested to use public transportation, bicycles or walk to reduce the emission of pollutants from vehicles.
Avoid outdoor activities: Especially between 1:00 p.m. and 7:00 p.m., when ozone concentrations are highest.
Protect vulnerable groups: Children, older adults and people with respiratory diseases should stay indoors and avoid intense physical exertion.
Control industrial emissions: Companies must adopt measures to reduce the emission of ozone precursors, such as volatile organic compounds (VOCs) and nitrogen oxides (NOx).++
The Environmental Commission of the Megalopolis indicated that it will continue to monitor atmospheric conditions and air quality, providing updates and recommendations to the population.
