What BDE 99?
BDE-99, but not BDE-47, is a transient aryl hydrocarbon receptor agonist in zebrafish liver cells. Toxicol Appl Pharmacol.
What BDE 47?
Polybrominated diphenyl ethers (PBDEs) are a class of brominated flame retardants that are used as additives in polymers for electric and electronic goods and in textiles1. 2,2′4,4′-tetrabromodiphenyl ether (BDE47) is the dominant PBDE congener in humans, wildlife, and the environment.
What is Hexabromodiphenyl ether?
Hexabromodiphenyl ether and heptabromodiphenyl ether (C-octaBDE) Commercial octabromodiphenyl ether (c-octaBDE) is a mixture of several polybrominated diphenyl ethers and congeners. These synthetic brominated compounds have mainly been used as flame retardants.
What is PBDE chemical?
Polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) belong to a class of chemicals that are added to certain manufactured products in order to reduce the chances that the products will catch on fire. Some PBDEs can build up in certain fish and mammals when they eat contaminated food or water.
What BDE 153?
BDE No 153 is a contaminant, which can also be commercially used as a flame retardant additive in building materials, textiles, plastics, and electronic equipment.
Are PBDE banned?
PBDEs have been widely used since the 1970s; however, due to their persistence in the environment, the manufacturing of PBDEs has been banned and the import, use and sale of PBDEs found in commercial mixtures of greatest concern (penta- and octaBDE) have been restricted in Canada since 2008 and in the US since the end …
Is PBDE banned in Australia?
Polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCDD) were used intensively as flame retardants, worldwide. Commercial Penta- and Octa-PBDE mixtures were banned in Australia in 2005, while HBCDD was banned worldwide in 2013.
What is PBB and PBDE?
Polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) are two groups of substances that are or have been used as flame retardants in plastic and textiles. Commercial PBDE and PBB products normally consist of a mix of substances with different numbers of bromine atoms.
What does PBDE stand for?
Polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs) belong to a class of chemicals that are added to certain manufactured products in order to reduce the chances that the products will catch on fire.
What does polybrominated diphenyl ethers do to you?
What are the routes of exposure and the potential health effects of PBDEs? ❖ Studies in rats and mice show that PBDEs cause neurotoxicity, developmental neurotoxicity, reproductive toxicity, thyroid toxicity, immunotoxicity, liver toxicity, pancreas effects (diabetes) and cancer (penta and decabromodiphenyl ether).
Are PBDEs banned in the US?
Brominated flame retardant chemicals, banned in the U.S. since 2004, still pollute the bodies of newborn American babies, according to a new study from Indiana University scientists. Polybrominated diphenyl ethers, or PBDEs, were once widely used in products including furniture foam and electronics.
Which Great Lake has the most PBDE?
Lake Ontario
Total PAH concentrations were higher in Lakes Erie and Ontario than in Lakes Michigan, Huron, and Superior. Total PBDE concentrations were highest in Lake Ontario (227 ± 75 pg/L), and the most abundant congeners were BDE-47, BDE-99, and BDE-209.
