Abstract

A rapid and simple method for the analysis of PBDEs in house dust is proposed. An "on batch" cleanup procedure was used for dust extracts treatment, which allowed to increase the speed of analysis. Experimental design analysis allowed obtaining the optimal conditions for microwave assisted solvent extraction process. Quantitative recoveries were obtained for all compounds and method precision was satisfactory. LODs (S/N=3) were lower than 0.15 ng/g dry mass for all compounds. Concentrations of total BDEs in house dust samples were lower than 200 ng/g, which is in agreement with the reported concentrations in samples from other EU countries. Dominant congeners in most of dust samples were those associated with pentaBDE commercial mixture.
