DescriptionLead37 days.jpg |
English: Dose of lead does not protrude before 2006* ) into food for 37 days, for an adult (human).
(* WHO has established in 2006 to lead a TWI (tolerable weekly intake) of 25 mcg/kg) Français : Cette petite bille de plomb correspondait à la dose de plomb à ne pas dépasser dans la nourriture, pour 37 jours, pour un être humain adulte avant 2006. Depuis (en 2006), l'OMS a réduit la DHT pour le plomb à 25 µg/kg de poids ; *, soit une dose journalière tolérable de 3,6 μg/kg pc/j). Le toxicologue se réfère à différents types de références (seuils, normes ou doses tolérables ou admissibles), dont « Dose Journalière Admissible » (DJA) (pour les résidus de pesticides) ; « Dose Journalière Tolérable » (DJT), « Dose hebdomadaire tolérable » (DHT) ou DHTP (« Dose hebdomadaire tolérable provisoire » ; « Dose Limite Annuelle » (DLA) (pour les radionucléides). Par exemple, la DHT était en France (avant 2006) fixée à 1500 µg/semaine pour le plomb (Source); pour l'Europe, Les taux max. en plomb (en mg/kg de poids frais) sont de 0,3 pour la chair (muscle) de poisson, 0,5 pour les crustacés, 1 pour les céphalopodes et 1,5 pour les mollusques bivalves. Ceci montre que même le plus petit plomb de pêche commercialisé correspond à une quantité de métal toxique significative. |
