Le terme "Liste Rouge" dans le contexte de l'environnement et du traitement des eaux fait référence à un outil crucial pour la sauvegarde de nos ressources en eau. Il désigne un groupe de substances considérées comme hautement dangereuses pour l'environnement, posant de graves menaces pour la vie aquatique et la santé humaine.
Le Royaume-Uni, en particulier, a développé une Liste Rouge complète contenant **23 substances** qui devraient être minimisées ou complètement éliminées des rejets dans les masses d'eau. Ces substances sont classées en fonction de leur toxicité, de leur persistance, de leur potentiel de bioaccumulation et de leur impact environnemental global.
Voici une ventilation des substances de la Liste Rouge, classées pour une meilleure compréhension :
1. Produits pharmaceutiques :
2. Produits chimiques industriels :
3. Autres substances :
La Liste Rouge sert d'outil vital pour :
En comprenant et en priorisant les substances de la Liste Rouge, nous pouvons travailler collectivement à la sauvegarde de nos ressources en eau et à garantir un avenir sain pour tous.
