Résumé:	L'amiante minéral naturel, classé cancérogène et interdit depuis 1997, reste encore présent dans de nombreux bâtiments et dans les milieux indutriels. Les expositions potentielles sont surveillées pour protéger la population et les professionnels susceptibles d'être exposés. Cependant il existe sur le territoire français des affleurement naturels d'amiante qui ne font l'objet d'aucune réglementation et de contrôles, et qui peuvent être une source non négligeable d'exposition de la population générale.
