Polybrominated diphenyl ether flame retardants in the U.S. marine environment: a review.
Polybrominated diphenyl ethers (PBDEs) are used as flame retardants in polymeric materials such as furnishing foam, rigid plastics and textiles. The U.S. has historically led the world production of these man-made chemicals and was responsible for about 50% of the total global demand in 2001. Paradoxically, scientific studies addressing sources, behavior and fate of PBDEs in the U.S. environmen...
متن کاملHuman Excretion of Polybrominated Diphenyl Ether Flame Retardants: Blood, Urine, and Sweat Study
Commonly used as flame retardants, polybrominated diphenyl ethers (PBDEs) are routinely detected in the environment, animals, and humans. Although these persistent organic pollutants are increasingly recognized as having serious health implications, particularly for children, this is the first study, to our knowledge, to investigate an intervention for human elimination of bioaccumulated PBDEs....
متن کاملPolybrominated Diphenyl Ether (PBDE) Flame Retardants and Thyroid Hormone during Pregnancy
BACKGROUND Human exposure to polybrominated diphenyl ether (PBDE) flame retardants has increased exponentially over the last three decades. Animal and human studies suggest that PBDEs may disrupt thyroid function. Although thyroid hormone (TH) of maternal origin plays an essential role in normal fetal brain development, there is a paucity of human data regarding associations between exposure to...
متن کاملAssociations between Polybrominated Diphenyl Ether (PBDE) Flame Retardants, Phenolic Metabolites, and Thyroid Hormones during Pregnancy
BACKGROUND Polybrominated diphenyl ethers (PBDEs) are chemical additives used as flame retardants in commercial products. PBDEs are bioaccumulative and persistent and have been linked to several adverse health outcomes. OBJECTIVES This study leverages an ongoing pregnancy cohort to measure PBDEs and PBDE metabolites in serum collected from an understudied population of pregnant women late in ...
متن کاملBioavailability of polybrominated diphenyl ether flame retardants in biosolids and spiked sediment to the aquatic oligochaete, Lumbriculus variegatus.
Polybrominated diphenyl ether (PBDE) flame retardants have become distributed ubiquitously in the environment. High concentrations have been reported in U.S. sewage sludge (biosolids). The burgeoning practice of land-applying biosolids as fertilizer creates an avenue for reintroduction of PBDEs to surface waters and aquatic sediments. Bioavailability of biosolids- and sediment-associated PBDEs ...
