Foodstuffs - Determination elements and their chemical species - Determination of organomercury in seafood by elemental mercury analysis
This document describes a method for the determination of organomercury in seafood/fishery products by elemental mercury analysis. The method has been successfully valideted in an interlaboratory study with a working range from 0,013 mg/kg to 5,12 mg/kg (HORRAT values <2) in seafood/fishery products [1], [2]. The limit of quantification is approximately 0,010 mg/kg organomercury (referring to dry weight, expressed as mercury) [3], [4].
Organic species of mercury, other than monomethylmercury, are also extracted and thus determined with this method. However, in seafood/fishery products the contribution from organic species of mercury other than monomethylmercury is negligible.
Lebensmittel - Bestimmung von Elementen und ihren Verbindungen - Bestimmung von Organoquecksilber in Fisch- und Meeresfrüchten mit Feststoffquecksilberbestimmung
Dieses Dokument legt ein Verfahren zur Bestimmung von Organoquecksilber in Fisch und Meeresfrüchten durch Nutzung eines Quecksilber Feststoff Analysators fest. Das Verfahren wurde in einem Ringversuch an Austerngewebe, Muschelgewebe, Hummer Hepatopankreas, Hundshaileber und Thunfisch mit Mengen von 0,01 mg/kg bis 5 mg/kg (bezogen auf das Trockengewicht und als Quecksilber ausgedrückt) erfolgreich validiert [1], [2].
Die Bestimmungsgrenze liegt bei etwa 0,01 mg/kg Organoquecksilber[3], [4].
Andere organische Quecksilberspezies als Monomethylquecksilber werden ebenfalls extrahiert und somit mit diesem Verfahren bestimmt. Bei Fisch und Meeresfrüchten ist der Beitrag anderer organischer Quecksilberspezies neben Monomethylquecksilber jedoch vernachlässigbar.
Produits alimentaires - Dosage des éléments et de leurs espèces chimiques - Dosage du mercure organique dans les fruits de mer par analyse du mercure élémentaire
La présente Norme européenne 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.
Živila - Določevanje elementov in njihovih kemijskih oblik - Določevanje organskih živosrebrovih spojin v morski hrani z analizo elementarnega živega srebra
Ta dokument opisuje metodo za določanje organskega živega srebra v morskih /ribiških proizvodih z elementarno analizo živega srebra. Metoda je bila uspešno potrjena v medlaboratorijski študiji z delovnim obsegom od 0,013 mg/kg do 5,12 mg/kg (vrednosti HORRAT < 2) v morskih sadežih/ribiških proizvodih [1], [2]. Meja količinskega določanja je približno 0,010 mg/kg organskega živega srebra (ki se navezuje na suho maso, izraženo kot živo srebro) [3], [4]. Organske vrste živega srebra, razen monometilnega živega srebra, se tudi ekstrahirajo in tako določijo s to metodo. Vendar pa je v morskih/ribiških proizvodih prispevek organskih vrst živega srebra, razen monometilnega živega srebra, zanemarljiv.
