Validation of a Horizontal Standard for the Determination of Polychlorinated Dibenzodioxins (PCDD), Polychlorinated Dibenzofurans (PCDF) and Dioxins-like Polychlorinated Biphenyls (DL PCB) in Soils, Sludges and Treated Biowaste Using High Resolution Mass Selective Detection (HR GC-MS) in a European Intercomparison Exercise

摘要

Project HORIZONTAL is interdisciplinary aiming at a harmonisation and horizontal standardisation of test procedures, in particular for sludge, soils and biowastes. In the context of this standardization project, a series of draft technical specification were designed upon an extensive desk study, fine-tuned after expert consultations and finally validated in international intercomparisons exercise.This report summarises the work performed within the validation study of the draft standard for the determination of polychlorinated dibenzodioxins (PCDD), polychlorinated dibenzofurans (PCDF) and dioxins-like polychlorinated biphenyls (DL PCB) in soils, sludge and treated bio-waste using high resolution mass selective detection (HR GC-MS). It further explains the underlying statistical concept for the calculation of reproducibility and repeatability from intercomparisons data. In addition all single values, results of the statistical evaluation as well as background information on the validation materials used are described and explained.
