Guidelines for the Determination of Halogenated Dibenzo-p-Dioxins and Dibenzofurans in Commercial Products (RE-ANNOUNCEMENT of PB88-101050 - see notes field for explanation)

摘要

The determination of halogenated dibenzo-p-dioxins (HDDs) and dibenzofurans (HDFs) in commercial products require specific and sensitive analytical procedures. The development of methods for the measurement of HDD and HDF in commercial products is complicated by the diverse range of matrices, the potentially large number of halogenated (specifically chloro, bromo, or bromo/chloro) HDD and HDF congeners and potential interference due to major components of the product matrices. The report provides (1) a review of the literature pertaining to commercial product analyses for HDDs and HDFs, (2) detail on the total number of bromo, chloro, and bromo/chloro HDDs and HDFs, (3) a tentative scheme for the analysis of HDDs and HDFs in diverse matrices, and (4) guidelines for the high resolution gas chromatography/mass spectrometry or electron capture detector analysis of commercial products for HDDs and HDFs. The guidelines specify a rigorous QA/QC program for the analysis of the commercial products.
