A week after the Environmental Contingency program was implemented, air quality remains poor throughout the Valley of Mexico. Tuesday morning, the Atmospheric Monitoring System (Simat) reported that three out of the five zones that make up the Valley of Mexico showed more than 100 Metropolitan Index of Air Quality (Imeca) units.Imeca units are the reference value for the levels of pollution for the inhabitants of Mexico City and the rest of the Valley of Mexico. When the Imeca index is between 0 and 50 units, the air quality is considered “good." Between 51 and 100 units, air quality is “regular." Between 101 and 150 units, air quality is “bad." Between 151 and 200 units, air quality is “very bad." Finally, when the index is over 201 units, air quality is “extremely bad."
