Through the General Directorate for the Prevention and Control of Atmospheric Pollution (DGPCCA) the SMA reported that at 8:00 p.m. a maximum value of 221 points of the Air Quality Index of suspended particles was recorded, PM2.5 fraction (171 micrograms per cubic meter), at the San Cristóbal Huichochitlán (SC) station, in the Municipality of Toluca.
The meteorological conditions and the thermal inversion that contributed to the concentration of PM2.5 particles, continue to be adverse for their dispersion (weak wind and atmospheric stability).
