Environmental solid matrices - Determination of polychlorinated biphenyls (PCB) by gas chromatography - mass selective detection (GC-MS) or electron-capture detection (GC-ECD) (ISO 18475:2023)
This document specifies methods for quantitative determination of seven selected polychlorinated biphenyls (PCB28, PCB52, PCB101, PCB118, PCB138, PCB153 and PCB180) in soil, sludge, sediment, treated biowaste, and waste using GC-MS and GC-ECD (see Table 2).
The limit of detection depends on the determinants, the equipment used, the quality of chemicals used for the extraction of the sample and the clean-up of the extract.
Under the conditions specified in this document, lower limit of application from 1 μg/kg (expressed as dry matter) for soils, sludge and biowaste to 10 μg/kg (expressed as dry matter) for solid waste can be achieved. For some specific samples the limit of 10 μg/kg cannot be reached.
Sludge, waste and treated biowaste may differ in properties, as well as in the expected contamination levels of PCB and presence of interfering substances. These differences make it impossible to describe one general procedure. This document contains decision tables based on the properties of the sample and the extraction and clean-up procedure to be used.
NOTE The analysis of PCB in insulating liquids, petroleum products, used oils and aqueous samples is referred to in EN 61619, EN 12766-1 and ISO 6468 respectively.
The method can be applied to the analysis of other PCB congeners not specified in the scope, provided suitability is proven by proper in-house validation experiments.
Feststoffe in der Umwelt - Bestimmung von polychlorierten Biphenylen (PCB) mittels Gaschromatographie und massenspektrometrischer Detektion (GC-MS) oder Elektronen-Einfang-Detektion (GC-ECD) (ISO 18475:2023)
Matrices solides environnementales - Dosage des polychlorobiphenyles (PCB) par chromatographie en phase gazeuse-spectrometrie de masse (CG-SM) ou chromatographie en phase gazeuse avec detection par capture d'electrons (CG-ECD) (ISO 18475:2023)
Le présent document spécifie les méthodes de dosage, par CG-SM et CG-ECD, de sept polychlorobiphényles choisis (PCB28, PCB52, PCB101, PCB118, PCB138, PCB153 et PCB180) dans les sols, les boues, les sédiments, les biodéchets traités et les déchets (voir Tableau 2).
La limite de détection dépend des composés à analyser, de l’équipement utilisé, de la qualité des réactifs chimiques utilisés pour l’extraction de l’échantillon et la purification de l’extrait.
Dans les conditions spécifiées dans le présent document, il est possible d’atteindre une limite inférieure d’application de 1 μg/kg (exprimée sur matière sèche) pour les sols, les boues et les biodéchets à 10 μg/kg (exprimée sur matière sèche) pour les déchets solides. Pour certains échantillons spécifiques, la limite de 10 μg/kg ne peut pas être atteinte.
Les boues, les déchets et les biodéchets traités peuvent présenter des différences en termes de propriétés, de niveaux prévus de contamination par les PCB et de présence de substances interférentes. En raison de ces différences, il est impossible de décrire un mode opératoire général. Le présent document contient des tables de décision basées sur les propriétés de l’échantillon ainsi que sur le mode opératoire d’extraction et de purification à utiliser.
NOTE Pour l’analyse des PCB dans les liquides isolants, les produits pétroliers, les huiles usagées et les échantillons aqueux, se référer respectivement aux normes EN 61619, EN 12766-1 et ISO 6468.
La méthode peut être appliquée à l’analyse de congénères de PCB autres que ceux décrits dans le domaine d’application, à condition d’en définir l’applicabilité par des tests de validation internes adaptés.
