Air Quality – Average Concentration – NO2 – PM2.5 – PM10 – O3 from 2004 to 2014

**Set of annual average pollutant concentrations (last 3 years rolling average) for NO2, PM10, fine PM2.5 and Ozone O3 from 2004 to 2014** Airparif monitors and analyses on a daily basis the long-term evolution of pollution levels according to the pollutants, and in particular the regulated pollutants, for each year and in all the municipalities of Paris. Concentrations of regulated pollutants have been decreasing in recent years in Paris and Île-de-France.However, concentrations of particulate matter and nitrogen dioxide remain problematic in Paris, with exceedances of the WHO regulatory limit values and health recommendation thresholds. For PM2.5 particulate matter, ozone (O3) measured concentrations meet the limit values but still exceed the quality targets. Since 2023, Airparif has distinguished the average annual traffic concentrations of the Peripheral Boulevard from that of the INTramuros for NO2 and PM10 and only from the Peripheral Boulevard for PM2.5. This breakdown could be calculated from 2015. This is why you have at your disposal another dataset [Air quality – Average concentration – NO2 – PM2.5 – PM10 – O3 as of 2015](https://parisdata.opendatasoft.com/explore/dataset/qualite-de-lair-concentration-moyenne-no2-pm25-pm10-o3-a-partir-de-2015/information/). NB: Nitrogen oxides (NOx) include nitrogen monoxide (NO) and nitrogen dioxide (NO2). The main emitters are motorised vehicles. NO2 is an irritating gas for bronchi. In asthmatics, it increases the frequency and severity of seizures. In children, it promotes lung infections._ **You can find all the Air Quality datasets[ICI](https://parisdata.opendatasoft.com/pages/catalogue/?disjunctive.theme&disjunctive.publisher&sort=modified&q=Qualit%C3%A9%20de%20l%27air&refine.publisher=Direction%20de%20la%20Transition%20%C3%89cologique%20et%20du%20Climat%20-%20Ville%20de%20Paris)** The data provider is Airparif >> [Annual Pollution Charts | Airparif](https://www.airparif.asso.fr/surveiller-la-pollution/bilan-et-cartes-annuels-de-pollution); [Monitored pollutants | Airparif](https://www.airparif.asso.fr/surveiller-la-pollution/les-polluants-surveilles) Link Paris.fr >> [Air and Sound Environment – City of Paris](https://www.paris.fr/air-et-environnement-sonore); [State of Air Quality in Paris – City of Paris](https://www.paris.fr/pages/etat-des-lieux-de-la-qualite-de-l-air-a-paris-7101); [Regulated and monitored air quality – City of Paris](https://www.paris.fr/pages/la-qualite-de-l-air-reglementee-et-surveillee-7100) ** __**
