Most authors used for their studies of technical decaBDE mixture, or pure congener BDE 209. Very few studies used the technical octaBDE mixtures or pentaBDE, or congener BDE 47, which are most abundantly represented in the environment. Photodegradation of PBDE by catalysis over nanoporous TiO2 in microwave field showed very positive results. Debromination of BDE 209 after 240 minutes was very high and reached 99% (from initial value of 14 125 ng/mL). Lower brominated congeners including the tri brominated congener BDE 28 were safely determined.
