  • Air pollution is one of the most severe problems worldwide, both in indoor and outdoor environments.

Environ , 2013, Vol. 77, pg. 149-154) and that exposure to NO2 is a potential inducer of neurological diseases (Li, FL , Chen, L., Guo, Z., Sang, N., Li, G., “In vivo screening to determine neurological hazards of nitrogen dioxide (NO 2) using Wistar rats”, J.

Abstract

La présente invention concerne un système de capture (1) pour éliminer des contaminants comme le NO2 présent dans l'air intérieur et extérieur au moyen de convertisseurs chimiques solides (5) non catalytiques à des températures basses, réduisant les risques pour la santé humaine et permettant une élimination hautement efficace à faible coût et sans libération de produits secondaires. Ce système est également un système de capture (1) d'empreinte carbone et d'énergie très faible, ce qui implique qu'il est, en même temps, économique, sans danger pour l'environnement et ne produit pas de composés secondaires libérés toxiques ou préjudiciables à la santé.
