Air quality - Average concentration - NO2 - PM2.5 - PM10 - O3 from 2004 to 2014

Dataset of annual average pollutant concentrations (rolling average of the last 3 years) for the nitrogen dioxide NO2, PM10 particles, PM2.5 fine particles and Ozone O3 from 2004 to 2014Airparif monitors and analyzes on a daily basis the long-term evolution of pollution levels according to pollutants, and in particular regulated pollutants, for each year and in all municipalities. The concentrations of regulated pollutants have been decreasing for several years in Paris and Île-de-France. However, the concentrations of particles and nitrogen dioxide remain problematic in Paris, with regulatory limit values ​​and WHO health recommendation thresholds are exceeded. For PM2.5 particles, ozone (O3) the concentrations measured comply with the limit values, but still exceed the quality objectives. Since 2023, Airparif has distinguished the average annual concentrations of traffic on the Boulevard Périphérique from that of the Intramuros for NO2 and PM10 and only on the Boulevard Périphérique for PM2.5. This breakdown may have been calculated from 2015. That's why you have another dataset at your disposal Air quality - Average concentration - NO2 - PM2.5 - PM10 - O3 from 2015. NB:Nitrogen oxides (NOx) include nitrogen monoxide (NO) and nitrogen dioxide (NO2). The main emitters are motorized vehicles. NO2 is a gas that irritates the bronchi.In asthmatics, it increases the frequency and severity of attacks.In children, it promotes lung infections.You can find all the Air Quality datasets HEREThe supplier of data is Airparif >> Annual pollution reports and maps | Airparif; Monitored pollutants | AirparifLink Paris.fr >> Air and sound environment - City of Paris; State of air quality in Paris - City of Paris; Regulated and monitored air quality - City of Paris
