Matrix solid-phase dispersion (MSPD) as simple and useful sample preparation technique for determination of polybrominated diphenyl ethers (PBDEs) in dust

Abstrakt

In the present study a novel analytical procedure for the determination of polybrominated diphenylethers in dust samples was developed.The main aim of the research was the selection of the optimum conditions of the matrix solid-phasedispersion before thefinal determination of polybrominated diphenyl ethers in dust samples. In order toassess the best usefulness of this technique, a favourable ratio of sample amount to the mass ofdispersing sorbent, as well as the type of this sorbent used has been tested. The type of sorbentresponsible for additional purification (clean-up sorbent) of the extract during matrix solid-phasedispersion was also selected. Gas chromatography coupled with mass spectrometry will be used at thefinal determination step.Preliminary results indicate that the use of matrix solid-phase dispersion can be a promising alter-native to other time-consuming and multi-stage analytical procedures. The proposed method providedsatisfactory recoveries (76e119%) and limits of detection: 2.1e4.4 pg/mikrogram for tri-heptaBDE in linear rangeof 5e100 pg/mikrogram; 480 pg/mikrogrm for decaBDE in linear range of 500e2000 pg/mikrogram from only 0.05 g of a dustsample. Finally, the method was applied to study the content of selected polybrominated diphenyl ethersin real dust samples.
