Research Abstract

Since PBDEs were listed in Stockholm Convention, halogenated alternative flame retardants and phosphorus flame retardants (PFRs) are of public concern. Contamination status and biomagnification of those alternative flame retardants were investigated in the coastal waters of Asia. Results suggest that PBDEs have been substituted by halogenated alternatives in industrialized nations. In addition, levels of triphenyl phosphate (TPhP) in fish showed a positive correlation with δ15N, indicating that it was biomagnifiedthrough food web.
