High Pollution Levels Detected in Paris Metro Stations

A new study reveals 13 stations exceed recommended fine particle thresholds, prompting calls for improved air quality measures.

Airparif's study analyzed air quality across 426 platforms in the Paris metro, revealing elevated fine particle pollution in 13 stations.
The worst-affected stations, including Belleville and Trocadéro, are on lines 2, 5, and 9, with PM10 levels surpassing 480 µg/m³.
The study highlighted the significant impact of train braking systems and ventilation on pollution levels.
Île-de-France Mobilités aims to address the issue by increasing transparency and implementing measures to reduce pollution.
Despite high pollution levels, no studies have conclusively linked metro air quality to respiratory illnesses according to RATP CEO Jean Castex.
