Water quality — Determination of polybrominated diphenyl ethers (PBDE) in sediment, suspended particulate matter and biota — Method using gas chromatography coupled with tandem mass spectrometry (GC-MS/MS) or with high resolution mass spectrometry (GC-HRMS) Published (Edition 2, 2026)

Abstract

This document specifies a method for the determination of selected polybrominated diphenylethers (PBDE) (see Figure 1 and Table 1) in sediment, suspended particulate matter and biota using gas chromatography coupled with tandem mass spectrometry (GC-MS/MS) or with high resolution mass spectrometry (GC-HRMS) in the electron impact (EI), negative ion chemical ionization (NCI) or atmospheric pressure ionization (APCI) mode.

The method is applicable to sediment and suspended particulate matter samples with limits of quantification of 0,2 µg/kg dry mass (dm) for brominated diphenylether (BDE) BDE-28 to BDE-183, of 2 µg/kg dry mass (dm) for BDE‑209.

The method is applicable as well with lower limits of quantification (LOQ), if specific clean-up methods, described in Clause 10, Table 3, method 1 and method 2 in combination with measurement methods GC-MS/MS or GC-HRMS after electron impact ionization (El) or negative ion chemical ionization (NCI) for BDE-209 are used. Depending on the analytical capability of the instrument, limits of quantification down to 0,003 µg/kg dm for BDE-28 to BDE-154 and 0,02 µg/kg dm for BDE-183 and 1 µg/kg dm for BDE-209 and lower are possible.

The method is applicable to biota samples with limits of quantification down to 0,000 2 µg/kg fresh mass (fm) (BDE-28 to BDE-154) and 0,03 μg/kg fresh mass (fm) (BDE-183), if specific clean-up methods, described in Table 4 in combination with measurement methods GC-MS/MS or GC-HRMS after electron impact ionization (El) are used.

Performance data are listed in Annex E.
