- •
Photodegradation of MeO-PBDEs in pure water is susceptible to their structures.
- •
1O2 and O2−
are photo-generated in the aerated MeO-PBDEs solutions.- •
1O2 can not oxidize MeO-PBDEs; while O2−
behaves contrarily.- •
Hydrodebromination is the major elimination pathway for MeO-PBDEs.
- •
Direct photolysis half-lives of MeO-PBDEs in the surface waters are evaluated.
