Background on CAMe and its Relevance
The Comisión Ambiental de la Megalópolis (CAMe) is a Mexican environmental agency responsible for monitoring and managing air quality in the Metropolitan Area of Mexico City. Its role is crucial as it ensures the well-being of millions of residents by providing timely information on air pollution levels and implementing measures to mitigate harmful effects.
Details of the Environmental Alert Suspension
On January 1, 2023, CAMe announced the suspension of a regional atmospheric environmental alert that had been activated earlier in the southeastern part of the Valley of Mexico.
At 8:00 AM, the PM2.5 concentration was recorded at 107.3 µg/m³ in the Santiago Acahualtepec (SAC) monitoring station, located in Mexico City’s Iztapalapa alcaldía. However, these conditions did not warrant the activation of the Hoy No Circula program.
CAMe attributed the increase in air contaminants primarily to the widespread use of fireworks and burning of materials and fuels during New Year’s celebrations.
Improving Air Quality Conditions
By 8:00 PM, most air quality monitoring stations in the Zona Metropolitana del Valle de México (ZMVM) reported acceptable and good PM2.5 air quality levels.
CAMe noted a decreasing trend in contaminant concentrations due to ventilation observed over the past few hours and favorable meteorological conditions that facilitated contaminant dispersion.
Impact on Residents
The suspension of the environmental alert means that restrictions imposed by the Hoy No Circula program are lifted. This program, which limits vehicle circulation based on license plate numbers, aims to reduce air pollution caused by traffic.
With the alert lifted, residents in the affected areas can now travel freely without worrying about program restrictions. However, it’s essential to remain vigilant regarding air quality and take precautions if levels worsen in the future.
