Foodstuffs - Determination elements and their chemical species - Determination of organomercury in seafood by elemental mercury analysis

Le présent document spécifie une méthode de dosage du mercure organique dans les produits de la mer par analyse du mercure élémentaire. La méthode a été validée au cours d'un essai interlaboratoires sur du tissu d'huître, du tissu de moule, de l'hépatopancréas de homard, du foie de roussette et du thon à des niveaux allant de 0,01 mg/kg à 5 mg/kg faisant référence au poids sec et exprimés en tant que mercure [1], [2]. La limite de quantification est d'environ 0,01 mg/kg de mercure organique [3], [4]. Les espèces organiques du mercure, autres que le monométhylmercure, sont également extraites et ainsi dosées avec cette méthode. Cependant, dans les produits de la mer, la contribution des espèces organiques du mercure autres que le monométhylmercure est négligeable.
