Article title: « Pollution in the Metro and RER: 13 stations beyond recommended thresholds »
The article discusses a study on air pollution in the Paris Metro and RER system, which found that 13 stations exceeded the recommended thresholds for nitrogen dioxide (NO2) and fine particulate matter (PM). The study was conducted by Airparif, an association that monitors air quality in the Ile-de-France region.
The 13 stations that exceeded the recommended thresholds were:
* NO2: Gare de Lyon, Gare du Nord, Gare de l’Est, Chatelet-Les Halles, Réaumur-Sébastopol, Strasbourg-Saint-Denis, and Place de Clichy.
* PM: La Chapelle, St-Lazare, Gare de l’Est, Gare du Nord, Chatelet-Les Halles, and Réaumur-Sébastopol.
The recommended thresholds for NO2 are 40 micrograms per cubic meter (μg/m3) for an annual average and 200 μg/m3 for a one-hour average. The recommended threshold for PM is 40 μg/m3 for an annual average.
The study found that the highest levels of pollution were measured during rush hour and at stations with underground connections to bus depots or taxi stands. The study’s authors recommend improving ventilation and filtration systems in the Metro and RER, reducing the use of diesel buses and taxis near stations, and raising public awareness about the health risks associated with air pollution.
