Ambient Air Monitoring Network Management

We have more than 40 years of experience in the management of air quality networks for both public administrations and private companies, always taking into account the legal requirements set out in Royal Decree 102/2011 and in the specific Integrated Environmental Authorisations (IEA) for each sector.

To date, Envira has managed more than 80% of the air quality networks in Spain.

Zoning Study

Our zoning studies are carried out as a first step to identify the emission sources according to the established requirements and to propose the most suitable locations for the monitoring stations.
Análisis preliminar
We carried out an initial geographical and social study of the area to determine the locations of the stations, taking into account the micro and macro implementation criteria set out in RD 102/2011, as well as important logistical issues relating to electrical connections, communications and access for subsequent maintenance work.
Pre-assessment and measurement campaigns
Once the locations of the monitoring stations have been proposed, a pre-assessment is carried out by means of preliminary measurement campaigns. In this way, the mobile air quality monitoring station verifies the presence of the expected pollutant parameters by taking samples in real time and in a given period.
