In the Valley of Mexico, the ozone season began, which extends from February to June. Currently, Mexico City and its surroundings in the State of Mexico are experiencing poor air quality issues, with elevated levels of pollutants, especially highlighted in the GAM, Ecatepec, and Tlalnepantla.
During a thermal inversion, where there is no air movement, pollutants accumulate, increasing their concentration and posing a risk to people's health, according to Aire CDMX.
Ozone negatively impacts health by irritating the respiratory system, which can cause a significant decrease in lung function. Because of this, the Doble Hoy No Circula program has been activated.
It has been forecasted that environmental contingencies could increase during the first half of 2025, with high temperatures in the region, according to reports from the Institute of Atmospheric Sciences and Climate Change of UNAM.
The atmospheric monitoring system of Mexico City detected two thermal inversions, a meteorological phenomenon that causes extreme atmospheric stability, primarily affecting children, the elderly, and individuals with respiratory problems.
On the other hand, a high level of solar UV radiation was noted, and it is recommended to use sun protection, such as long-sleeved cotton clothing, hats, UV-filtering glasses, and SPF 30+ sunscreen to avoid damage from sun exposure. Last week, the environmental contingency due to ozone was activated in the Valley of Mexico due to high concentrations of this pollutant.
