Reference Concentration (RfC): The RfC is an estimate (with uncertainty spanning perhaps an order of magnitude) of a continuous inhalation exposure to the human population (including sensitive subgroups which include children, asthmatics and the elderly) that is likely to be without an appreciable risk of deleterious effects during a lifetime. It can be derived from various types of human or animal data, with uncertainty factors generally applied to reflect limitations of the data used. 2, record 1, English, - reference%20concentration

On peut considérer qu'il existe un cour de doctrine accepté par toute la communauté scientifique et qui s'exprime notamment dans les lignes directrices de l'US EPA [United States Environmental Protection Agency] et le Guide technique de l'Union européenne. On considère [qu'il] existe un seuil d'effet pour les effets de type systémique. Ce seuil, appelé «dose de référence (DRf)» ou «concentration de référence (CRf)», est calculé en appliquant à la DSENO (dose sans effet nocif observé) déterminée par expérimentation animale des facteurs de sécurité. 2, record 1, French, - concentration%20de%20r%C3%A9f%C3%A9rence

Il existe une nuance entre «teneur» et «concentration». «Teneur» désigne la quantité de matière contenue dans un corps, par exemple : teneur en or d'un minerai, alors que «concentration» désigne la proportion d'un composant dans une solution, un mélange, par exemple : concentration en masse, en volume, concentration forte, faible. Dans ce contexte le terme «teneur» est à éviter. 5, record 1, French, - concentration%20de%20r%C3%A9f%C3%A9rence
