According to a 2016 report from the Integral Environmental Monitoring System of Nuevo León, in the last 14 years, there has been an average of 272 days of poor air quality per year, in the Monterrey Metropolitan Area.

The main types of pollutants registered in the Monterrey Metropolitan Area are:

  • Natural sources. Due to the orography, geography and atmospheric conditions, pollution is generated naturally (28%).

  • Mobile sources. Cars, trucks, trailers, among others (45%).

  • Area sources. Commercial, domestic or service activities that raise land (16%).

  • Fixed sources. All industries (11%).

This situation is of special importance, because there is a direct relationship between the presence of pollutants and certain types of diseases that affect public health, among which are the following:

  • Those that cause respiratory diseases.

  • Associated with heart problems.

  • In extreme cases they cause deaths.

For this reason and with the purpose of contributing to the improvement of air quality, the Autonomous University of Nuevo León hosts since October 4, 2017 a new environmental monitoring station, located in the parking lot of the Center for Business Development and Postgraduate of FACPYA, and that was installed thanks to the collaboration of the Autonomous University of Nuevo León, through the Secretary of Sustainability, with the Government of the State of Nuevo León, through the Secretariat of Sustainability.

This new system installed to the north of the University City of the UANL, adds to two more that were inaugurated in 2017: in Pueblo Serena, south of the metropolitan area, and in the suburban municipality of Cadereyta, to add a total of 13 stations in the entity.

The operation of the station is fully automated, so it does not require technical personnel, to perform the following functions:

  • Ensures the measurement of pollutants and meteorological parameters, allowing to keep a historical record of the air quality every hour.

  • Pollutants: particles smaller than 2.5 micrometers, particles smaller than 10 micrometers, sulfur dioxide, ozone, nitrogen oxides, ammonia, hydrogen sulfide and carbon monoxide.

  • Meteorological parameters: temperature, solar radiation, atmospheric pressure, wind direction and speed, rainfall and relative humidity.
