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.

The identities of several PBDE congeners are shown in Table 4-1 (WHO 1994a, 1994b). In the United States, Albemarle Corporation and Great Lakes Chemical Corporation previously marketed A decrease of PBDE concentrations in Swedish milk has also been indicated by Lind and co-workers 2003 (10). 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 ).

They are prohibitively expensive and have no interpretable reference ranges for clinical outcomes. 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. Halterna av PBDE ökar hela tiden i naturen och är liksom PCB svårnedbrytbart.

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 Search results for PBDE at Sigma-Aldrich. Compare Products: Select up to 4 products. *Please select more than one item to compare PBDE namnges beroende på hur många bromatomer molekylen innehåller. Det finns mono-, di-, tri-, tetra-, penta-, hexa-, hepta-, okta-, nona- och dekaBDE, där det maximala antalet bromatomer är tio. PBDE delas också upp med avseende på bromatomernas placering på fenylringarna.

Several studies demonstrate PBDEs are found in the form of a number of closely related chemicals, known as congeners. PBDEs have come under increased scrutiny because of their potential 3 ส.ค. 2014 Polybrominated biphenyl (PBBs).

Each of these commercial products is a mixture composed of several PBDE congeners.
