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

izing PBDE additives in polymers since the desire is not so much the complete separation as it is the overall composition and contribution of the various isomers [5

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. Polybrominated diphenyl ethers (PBDEs) are used in large quantities as flame-retardant additives in a number of commercial products. Biomonitoring data show that, in recent years, PBDE concentrations have increased rapidly in the bodies of wildlife and humans. 2009 PBDE Flame Retardant Legislation On December 17, 2009, the principal manufacturers of decaBDE, Albemarle Corporation and Chemtura Corporation, and the principal importer, ICL Industrial Products, Inc., announced their commitment to a three-year phase-out of decaBDE.

PBDE levels reported in children are usually higher than the levels detected in adults. Children are exposed to PBDEs mainly by absorbing PBDE from their indoor environment, from use of consumer products including toys, and from their diet. PCB och PBDE är båda fettlösliga organiska industrikemikalier. PCB är sedan många år förbjudet eftersom det visade sig biomagnifieras i fiskätande däggdjur och fåglar samt skada dessa.

Polybrominated diphenyl ethers (PBDEs) have been widely used to flame-retard products common in homes and the workplace, and subsequently, they have become widely dispersed in the environment.

These studies observed problems with learning, memory, and behavior in mice and rats. Animal studies also found that PBDEs can alter thyroid and other hormone levels.

PBDEs and therefore is defined for edible parts of fish. The value is a sum of PBDE congeners 28, 47, 99, 100, 153 and 154, mainly representing penta- and octa- but not decaBDE.

sPBDE utgör summan av 5 BDE-kongener (BDE28 har inte ingått i analyserna varje år och har därför exkluderats från summeringen).

Till skillnad från PCB Polybromerade difenyletrar (PBDE) är en samlingsbeteckning för ett antal av de mest använda bromerade flamskyddsmedlen med stor spridning i miljön. Ämnena är fettlösliga och lagras i fisk. Tillverkningen av varor och produkter med flamskyddsmedel är mycket stor. 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. PBDEs are ubiquitously present in the environment and likewise in biota and in food and feed.

MeO-PBDE och OH-PBDE mönstret varierar i de olika lokalerna och i de olika arterna. Resultaten tyder möjligen på en viss samvariation mellan halten MeO-PBDE och halten PBDD, speciellt på kongenerbasis.

They are added to products such as foam padding, textiles, or plastics to retard combustion. 2,2′,4,4′,5,5′-hexabromobiphenyl (BB-153) is a brominated biphenyl that was used as a flame retardant in the U.S. until the 1970s. PBDE flame retardants were commonly added to furniture, infant products, and electronics for many years.

Production of PBDEs in the U.S. began in the 1970s and peaked in the late 1990s. Se hela listan på naturvardsverket.se Se hela listan på livsmedelsverket.se Commercial pentaBDE is a technical mixture of different PBDE congeners, with BDE-47 (2,2',4,4'- tetrabromodiphenyl ether) and BDE-99 (2,2',4,4',5-pentabromodiphenyl ether) as the most abundant. The term pentaBDE alone refers to isomers of pentabromodiphenyl ether (PBDE congener numbers 82-127).

pbde Polybrominated diphenyl ethers (PBDEs) are a class of synthetic halogenated organic compounds used in numerous polymer-based commercial and household products, such as textiles, furniture, and electronics, to increase their flame ignition resistance and to meet increasingly strict fire safety standards (Shaw and Kannan, 2009).

There are three commercial PBDE mixtures that have primarily been used: Penta-, Octa- and Deca-bromodiphenylether, where the nomenclature reflects the number of bromine atoms included in the main components in the mixture. Sum PBDE levels increased significantly in the serum of the exposed females from 218 +/- 43 to 23,400 +/- 2035 pg/mL.
