Dans la lutte contre la pollution atmosphérique, le terme "Econ-NOx" est apparu comme un phare d'espoir. Il désigne une approche globale de contrôle des émissions d'**oxydes d'azote (NOx)**, un contributeur majeur au smog, aux pluies acides et aux problèmes respiratoires. Si "Econ" implique l'efficacité économique, c'est le "NOx" qui met en avant la réduction ciblée de ces polluants nocifs.
La Menace des Émissions de NOx
Les émissions de NOx, principalement issues des processus de combustion dans les industries et les transports, constituent une préoccupation environnementale majeure. Elles forment de l'ozone troposphérique, un élément clé du smog, et contribuent aux pluies acides, endommageant les écosystèmes et les infrastructures. L'inhalation de NOx peut entraîner des maladies respiratoires, affectant particulièrement les populations vulnérables comme les enfants et les personnes âgées.
