AIR TO GO : THE MAP OF POLLUTION IN LYON

For the National Clean Air Day, ATMO Rhône-Alpes observatory has presented his application « Air To Go » in Android. Thanks to his 90 stations, including 20 in the region, the observatory succeeded in drawing an accurate map of air quality. She provides an overall index that mixes three polluants: nitrogen dioxide, ozone and suspended particles.

ATMO revealed its data on Lyon. The main circulating axes in the periphery or in the center are the most polluted in the department: A7, A6, A47, peripherals, entrances and exits of tunnel of Croix-Rousse, Fourvière and Caluire. But, major urban roads are particularly affected, such as the Berthelot’s avenue, Gambetta’s street, The climb of Choulans, the quayside…

« We have established thaht 48 000 inhabitants of metropolitan of Lyon (who live close to these roads) have been exposed to nitrogen oxides by 2016. Road transport accounts for 60% of nitrogen dioxide emission » explain Isabelle Clostre of ATMO Auvergne-Rhône-Alpes observatory. By, Le Progrès, 90% of these emissions are caused by diesel cars.

The industrial pollution, with sulfur dioxide visible on the application by large red plates are located of the south of Lyon, in Feyzin or Saint-Fons. "The flare of Feyzin, it's very visually striking. But with new technologies, particularly in terms of filtration, manufacturers have made serious efforts to reduce these emissions. They have fallen by 70% in fifteen years."

The west of the department, cut in half by the passage of the A89 is the least polluted place.
