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. Med biomagnifiering menas att koncentrationen av en kemikalie är högre i djur som befinner sig högre upp i näringskedjan, det vill säga djur som har en högre trofinivå. Till skillnad från PCB

PBB eller PBDE, som anges i artikel 4 i Europaparlamentets och rådets direktiv 2002/95/EG [6], får inte användas i värmepumpen eller värmepumpssystemet, med beaktande av de toleranser som anges i beslut 2005/618/EG [7], om ändring av direktiv 2002/95/EG.

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. PBDEs are ubiquitously present in the environment and likewise in biota and in food and feed. Data from the analysis of 19 PBDE congeners in 3,971 food samples PBDE: Polybrominated Diphenyl Ether: PBDE: Pentabromodiphenyl Ether (flame retardant additive in plastics) PBDE: Post-Baccalaureate Diploma in Education (Canada) PBDE: Planungsgesellschaft Bahnbau Deutsche Einheit (German: German Construction Company Planning Unit) PBDE… polybrominated diphenyl ethers: (pōl″ē-brōm′ĭ-nāt″ĕd), PBDE A class of chemicals used as flame retardants. They are chemically related to polychlorinated biphenyls and are thought to have similar biological toxicity. They have been found in streams, marine animals, human fetuses, and … Pentabromodiphenyl ethers (PBDE) are found in human tissue, in household dust, and in the environment, and a particular concern is the potential for the induction of cancer pathways from these fat-soluble persistent organic pollutants.

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. There is limited evidence of adverse effects in humans. relatively low PBDE exposure • PBDEs have half-lives in the body that are substantially shorter compared to other persistent organic pollutants. This means that the effect of past PBDE exposure is observable for a shorter period and current PBDE blood concentrations reflects more recent exposure Polybrominated diphenylethers (PBDE) belong to the group brominated flame retardants.

Halterna av PBDE ökar hela tiden i naturen och är liksom PCB svårnedbrytbart.

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.

These temporal trend studies all indicate decreasing PBDE concentrations, Polybrominated diphenyl ethers (PBDEs) are a group of congeners, mainly used as flame retardants in a variety of materials including plastics, textiles, electronic products, building materials, furnishings and vehicles ( Figure 1 ). PBDEs may enter the environment through emissions from manufacturing processes, evaporation from products that leaching, or degradation of PBDE -containing products.

Polybrominated diphenylethers (PBDE) and hexabromocyclododecane (HBCD) in paired samples of blood serum and breast milk – a correlation study . Sanna Lignell, Marie Aune, Anders Glynn, Tatiana Cantillana, Martin Isaksson . 2013-03-28

Polybrominated diphenylethers (PBDE) and hexabromocyclododecane (HBCD) in paired samples of blood serum and breast milk – a correlation study . Sanna Lignell, Marie Aune, Anders Glynn, Tatiana Cantillana, Martin Isaksson . 2013-03-28 2001-07-25 · Polybrominated diphenyl ether, PBDE, flame retardants are now a world-wide pollution problem reaching even remote areas. They have been found to bioaccumulate and there are concerns over the health effects of exposure to PBDEs, they also have potential endocrine disrupting properties. PBDE congeners (La Guardia et al., 2006).

These tests are not routinely available at the doctor’s office, but samples can be sent to laboratories that have the appropriate equipment.

In Norway, PBDE concentrations in human milk increased from 1986 to 2001 (11), within a similar concentration range as reported in Sweden and in Japan (8-10,12). These temporal trend studies all indicate decreasing PBDE concentrations, Polybrominated diphenyl ethers (PBDEs) are a group of congeners, mainly used as flame retardants in a variety of materials including plastics, textiles, electronic products, building materials, furnishings and vehicles ( Figure 1 ).

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. 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.

PBDEs are no longer produced in the U.S. but are still present in many items in our homes and elsewhere.
