Polybrominated diphenyl ethers and their derivatives in edible seafood
Presentation Abstract
Polybrominated diphenyl ethers (PBDEs) are a class of additive flame retardants that were historically used in furniture and electronics. PBDEs were phased out in the early 2000’s after they were found to persist in the environment and bioaccumulate in aquatic organisms. Methoxylated (MeO-) and hydroxylated (OH-) derivatives of PBDEs are also found in the marine environment and it’s debated, although likely, that they are natural marine byproducts. Humans are exposed to PBDEs via inhalation or ingestion of contaminated dust and food. Since PBDEs bioaccumulate in marine organisms, seafood is thought to be the main dietary exposure route for MeO- and OH-PBDEs. Humans can also metabolize certain PBDEs into the more harmful OH- form. We hypothesize that a seafood-rich diet can contribute to higher levels of MeO-PBDEs in blood plasma. To understand the approximate dietary exposure to PBDEs via seafood, various seafood items were collected from grocery stores in Sequim, WA and analyzed for parent, MeO- and OH-PBDEs.
