Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

Harbour porpoises (Phocoena phocoena) are one of three cetacean species inhabiting the Black Sea. PCBs (polychlorinated biphenyls) and PBDEs (polybrominated diphenyl ethers) are two types of lipophilic compounds which are banned in Europe since the 1970s (for PCBs) and 2004 (for PBDEs). Despite this, they are still present in the environment and can cause toxic effects in wildlife, including marine mammals. Recently, attention has been drawn towards the presence of naturally-produced methoxylated PBDEs (MeO-PBDEs) in marine mammals. These compounds can biomagnify in the food chains, acting in the same way as the anthropogenically-produced PBDEs. This is the first study to report on PBDEs and naturally-producedcompounds (MeO-PBDEs and PBHDs) in tissues (kidney, brain, blubber, liver, muscle) from male harbourporpoises (11 adults, 9 juveniles) from the Black Sea. Lipid-normalized concentrations decreased from muscle >blubber > liver > kidney > brain for the sum of PCBs and of PBDEs. Among the naturally-produced compounds,levels of PBHDs were higher than of MeO-PBDEs with tri-BHD and 6-MeO-BDE 47 being dominant for bothgroups, respectively. Concentrations of naturally-produced compounds decreased from blubber to brain, a profile which was the same as for the sum of DDXs. Concentrations of DDXs were highest, followed by PCBs, HCB, PBHDs, PBDEs and MeO-PBDEs. Levels of PCBs and PBDEs in blubber were lower than concentrationsreported for blubber of harbour porpoises from the North Sea.
