*"**Anthropogenic (PBDE) and naturally-produced (MeO-PBDE) brominated
**compounds
in cetaceans **-- **A review"*


*Science of the Total Environment 481: 619-634 *




ABSTRACT: This paper reviews the available data on brominated flame
retardants, the polybrominated diphenyl ethers (PBDEs), as well as on the
naturally-produced methoxylated polybrominated diphenyl ethers (MeO-PBDEs)
in cetacean tissues around the world. Levels and possible sources of both
compound classes are discussed. Odontocete cetaceans accumulate higher PBDE
concentrations than mysticete species. PBDE contamination was higher in
cetaceans from the Northern hemisphere, whereas MeO-PBDE levels were higher
in animals from the Southern hemisphere. Southern resident killer whales
from NE Pacific presented the highest levels reported in biota, followed by
bottlenose dolphins from North Atlantic (U.K. and U.S. coast). Many species
presented PBDE concentrations above threshold levels for health effects in
odontocetes. Time trend studies indicate that PBDE concentrations in
odontocetes from Japan, China, U.S. and Canada coastal zones have increased
significantly over the past 30 years. Studies from U.K. waters and NE
Atlantic showed a decrease and/or stability of PBDE levels in cetacean
tissues in recent decades. The highest MeO-PBDE concentrations were found
in dolphins from Tanzania (Indian Ocean), bottlenose dolphins from
Queensland, Australia (SW Pacific), and odontocetes from coastal and
continental shelf waters off southeastern Brazil (SW Atlantic). The
upwelling phenomenon and the presence of coral reef complexes in these
tropical oceans may explain the large amounts of the naturally-produced
organobromines. Considering that these bioaccumulative chemicals have
properties that could cause many deleterious effects in those animals,
future studies are required to evaluate the potential ecotoxicological
risks.
