PBDE exposure during fetal brain development is associated with deficits in cognitive function and behavior, including lower scores for full scale IQ (FSIQ), language, memory, reading, and executive function, as well as increased hyperactivity and attention problems

Each of these commercial products is a mixture composed of several PBDE congeners. PBDEs are used as flame retardants in a number of applications, including Pentabromodiphenyl ether is a brominated flame retardant which belongs to the group of polybrominated diphenyl ethers. Because of their toxicity and persistence, their industrial production is to be eliminated under the Stockholm Convention, a treaty to … Polybrominated diphenyl ethers (PBDE), which belong to a class of brominated hydrocarbon and are sometimes likened to brominated flame retardant (BFR) chemicals, have been widely utilized in the United States since the 1970s. Synonym: 2,3,3′,4,4′,5,5′,6-OctaBDE, 2,3,3′,4,4′,5,5′,6-Octabromodiphenyl ether solution, PBDE 205.

As part of NOAA's Mussel Watch Program, PBDEs are one of 150 different contaminants that are continually monitored by periodically sampling bivalves and sediment at 300 coastal sites around the nation. 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. Polybrominated diphenyl ethers or PBDEs, are a class of organobromine compounds that are used as flame retardants. Like other brominated flame retardants, PBDEs have been used in a wide array of products, including building materials, electronics, furnishings, motor vehicles, airplanes, plastics, polyurethane foams, and textiles. Polybrominated diphenyl ethers (PBDEs) include the commercial versions of pentabromodiphenyl ether (c-pentaBDE), octabromodiphenyl ether (c-octaBDE), and decabromodiphenyl ether (c-decaBDE). Each of these commercial products is a mixture composed of several PBDE congeners.

Hence … decabromodiphenyl ether (one type of PBDE) throughout their lives, developed liver tumors. Based on this evidence, the EPA has classified decabromodiphenyl ether as a possible human carcinogen. PBDEs with fewer bromine atoms than decabromodiphenyl ether are listed by the EPA as not classifiable as to human carcinogenicity due to the lack EFSA was asked by the European Commission to deliver a scientific opinion on polybrominated diphenyl ethers (PBDEs) in food. PBDEs are additive flame retardants which are applied in plastics, textiles, electronic castings and circuitry.

DDT-besprutning förbjöds i början av 70-talet. Det lanserades som ett tämligen riskfritt insektsmedel men upptäcktes vara ett långlivat gift i naturen som tas upp i näringskedjorna och även drabbar människor. Giftet lagras i kroppens fettdepåer med kronisk påverkan på organismen som följd. DDT används i en del länder utanför EU. PCB, polyklorera Kontrollera 'PBDE' översättningar till spanska. Titta igenom exempel på PBDE översättning i meningar, lyssna på uttal och lära dig grammatik. Polybrominated diphenyl ethers (PBDEs) are used as flame retardants in plastics (concentration, 5--30%) and in textile coatings. Commercial products consist predominantly of penta-, octa-, and decabromodiphenyl ether mixtures, and global PBDE production is about 40,000 tons per year.
