Monitoring air quality in Mexico DF

Mexico City, together with the state of the same name, is one of the biggest urban areas in the world, with a population of 22 million people. There, human activity and poor geographical and weather conditions can sometimes cause very high pollution concentrations.

It is one of the places in the world where there is the most concern and awareness of the problem of air quality, with the first monitoring work dating back to the late 1950s.

Nowadays, the SIMAT (System of the Federal District Secretariat of Environment) consists of the Automatic Air Quality Monitoring Network (RAMA), with 34 stations; the Manual Air Quality Monitoring Network (REDMA), with 12 stations; the Atmospheric Deposition Monitoring Network (REDDA), with 16 sampling points; and the Meteorological and Solar Radiation Monitoring Network (REDMET), with 16 stations.

In February 2014, two Nanoenvi devices were supplied in order to prove the feasibility of air quality indicative measuring with Nanoenvi equipment.

The first device was placed at three points in Naucalpan City

  • Point 1: Naucalpan City
  • Point 2: FES Acatlan monitoring station
  • Point 3: Satelite Civic Center

The second device was placed in the Vallejo Area, on the roof of the Automatic Air Quality Monitoring Network laboratory.

It can be inferred from this campaign that equipment with Nanoenvi technology can fully undertake indicative air quality measuring, as it provides high-availability (above 90%) data and a very reasonable comparison with reference methods.
