Naturally produced brominated phenoxyphenols (OH-PBDEs) and phenoxyanisoles (MeO-PBDEs) were analyzed in aquatic plants (16 genera of green, brown, and red algae and angiosperms) collected from Luzon Island, the Philippines. Two brominated phenoxyphenols, 2'-hydroxy-2,3',4,5'-tetrabromo-diphenyl ether (2'-OH-BDE68) and 6-hydroxy-2,2',4,4'-tetrabromodiphenyl ether (6-OH-BDE47), were detected in the phenolic fraction of extracts from most of the specimens; Sargassum oligosystum had the highest concentrations (101 ng/g fresh weight (fw)). The corresponding phenoxyanisole, 21-methoxy-2,3',4,5'-tetrabromodiphenyl ether (2'-MeO-BDE68), was most abundant in Sargassum aff. bataanense (229 ng/g fw), followed by Padina sp., and 6-methoxy-2,2',4,4'-tetrabromodiphenyl ether (6-MeO-BDE47) was predominant in Jania adhaerens (29 ng/g fw). Hydroxy-pentaBDEs, hydroxy-methoxy-tetraBDEs, dihydroxy-tetraBDEs, dihydroxy-tetrabromobiphenyl, and hydroxy-tetrabromodi-benzo-p-dioxins were also detected. The present study demonstrates that these aquatic plant species could be an abundant source of OH-PBDEs and MeO-PBDEs found in higher trophic organisms in the Asia Pacific region.
