The maps on this page describe the air quality in the vicinity of major Ile-de-France airports (Paris-Charles de Gaulle, Paris-Le Bourget and Paris-Orly). This is daily information on the levels of air pollutants to which local residents are exposed. The information is available for the day before, taking into account the actual flights for the entire day at each airport (including emissions from the landing, takeoff, taxiing and ascent/descent phases).
These maps come from the SURVOL project, providing information on the main environmental nuisances generated by the major Ile-de-France airports, namely air pollution and noise. SURVOL is an action of Regional Health Environment Plan (PRSE) which asks in its third part to improve the monitoring and decision support system in terms of management of airport environmental nuisances (action 3.2 of PRSE 3 managed by the General Directorate of Civil Aviation).
The air quality monitoring platform has been available since January 2013; it was developed by Airparif with the financial support of theIle-de-France Regional Health Agency. Beyond the air quality maps made available, Airparif carries out annual air quality assessments in the vicinity of these airports. These reports describe pollution levels, their situation with regard to limit values and the impact of airport activities on air quality. Measurement campaigns around airport platforms are also carried out regularly to ensure the quality of this monitoring system.
What pollution around airports?
For Paris-Charles de Gaulle and Paris Le Bourget
The maximum levels in DO NOT2 are encountered right and in the immediate vicinity of the main roads in the study area (notably the Boulevard Périphérique, the A1, A3, A86, A104 motorways and the RN1 and RN2 national roads), where severe exceedances of regulatory values are observed . Beyond the proximity of these axes, the limit value is respected for NO2. In 2020, around 10 people were potentially exposed to air exceeding the annual limit value in DO NOT2 on the study area.
The regulatory values for PM10 are also respected in the background. However, they are occasionally exceeded to the right and in direct proximity to certain portions of major Parisian and regional routes. The annual limit value for particles PM2.5 (set at 25 µg/m3 on average) is respected throughout the area. The entire study area and its inhabitants nevertheless remain affected by exceeding the quality objective, as well as the recommendation of theWHO.
In terms of nitrogen oxides (NOx), the impact distance linked to airport activities (air traffic and ground activities excluding induced traffic) around the Paris-Charles de Gaulle platform is variable: from 1 kilometer to the south of the platform and can reach up to approximately 2.5 kilometers (maximum estimated from the northeast of the Paris-CDG zone).
The maximum relative contribution of airport activities to NOx concentrations is between 15 and 20% in the immediate vicinity of Paris-Charles de Gaulle airport.
These contributions decrease with distance from the airport. 1 km from the platform, airport activities contribute between 5 and 10% to total nitrogen oxide concentrations.
Contributions (in %) of airport sources of nitrogen oxides in the Paris-Charles de Gaulle/Paris-Le Bourget area for the year 2020
Regarding particles PM2.5 et PM10, the impact of the activities of Paris-Charles de Gaulle airport is not perceptible on all airport platforms.
The contribution of nitrogen oxide emissions associated with airport activities is very low (less than 4%) and limited to the actual area of the Paris-Le Bourget platform.
For Paris-Orly (in 2020)
The maximum levels in DO NOT2 are encountered right and in the immediate vicinity of the main roads in the study area (in particular the A6 (a, b), A86, A10 motorways and the RN7, RN6, etc. national roads), where regulatory values are exceeded . In 2020, around 7 people were potentially exposed to air exceeding the annual limit value in DO NOT2 on the study area.
In the area of study, in 2020, the regulatory values for PM10 and PM2.5 are respected. The entire study area and its inhabitants remain affected by exceeding the WHO recommendations for particles (and the quality objective resulting from French regulations).
In terms of nitrogen oxides (NOx), the impact distance of airport activities around Paris-Orly airport is between 200 meters (north of the platform) and 300 meters (south). The maximum relative contribution of airport activities to NOx concentrations is around 8%.
Contributions (in %) of airport sources of nitrogen oxides (NOx) in the Paris-Orly area for the year 2020
The contribution of primary particle emissions (PM10 et PM2.5) from the activities of Paris-Orly airport at concentrations is less than 4%, including on the platform. The importance of other sources (road traffic, residential and tertiary heating, industries, etc.) explains this observation. Particle sources are generally more diffuse and therefore background particle concentrations are more homogeneous.
