PBDEs have been linked to the following damaging health effects, in some cases at levels that are at or near those observed in the U.S. population: • Learning, behavior, and memory problems. Studies in rodents indicate exposure to PBDEs during brain development has permanent effects on learning, memory, and behavior. (Viberg 2003).

Furthermore, several regional studies have shown increasing concentrations in human milk, tissue, and serum samples, with the most prevalent PBDE congeners in human samples being PBDE-47 and PBDE-99. Therefore, the widespread uses of PBDEs and increased amount of contamination in the environment have led to rising concern about the possible adverse health effects in humans.

The only U.S. supplier of the "penta" PBDE variety used in mattress foam has impacts, är ett Marie Curie Initial Training Network (ITN)-projekt inom EU:s sjunde ramprogram. PBDE. Polybromerade difenyletrar. Olika nummer för olika ingående kompo- nenter E. Creating A Healthy Indoor Air Quality In School.

Even though there is little information on the health effects of PBDE exposure, it is still of concern to humans because some types of PBDEs can build up in the fatty tissues of the body and in breast milk. ENVIRONMENTAL HEALTH – CONTAMINANTS FACT SHEETS If you would like this information in another official language, contact us at 1-855-846 2016-10-25 · Health Effects: PBDEs are organobromine compounds, and are structurally similar to now-banned PCBs (Polychlorinated biphenyls) which is a well known persistent toxic chemical. Moreover PBDEs are similar in shape to thyroid hormone, and thus interferes with the hormone activities of the body. Both PBDEs and PCBs biomagnify in the food chain.

potential PBDE health effects. The California Department of Health Services (DHS) also contributed expertise and provided representatives to the Cal/EPA PBDE Workgroup.

Background Polybrominated diphenyl ethers (PBDEs) are used as flame retardants in many household items. Given concerns over their potential adverse health effects, we identified predictors and evaluated temporal changes of PBDE serum concentrations. Methods PBDE serum concentrations were measured in young children (2-8 years old; N = 67), parents of young children (<55 years old; N = 90), and

Human studies already document adverse effects on intelligence and psychomotor skills in children with disruptions in thyroid levels in the womb through the second year of life. 19-22 One study found that workers exposed to PBDEs experienced higher prevalence of hypothyroidism. 23 Concurrent exposure to both PBDEs and PCBs, as from consuming some fatty fish, may present an increased risk since some researchers have found additive or synergistic effects between the two chemicals.

The Stockholm Trial – Effects on Air Quality and Health Hydroxy-PCBs, PBDE and HBCDD in serum from an elderlypopulation of Swedish fishermen's wives

Studies have linked them to reproductive and neurological risks at certain concentrations or higher. The chemical has no proven health effects in humans; however, based on animal experiments, pentaBDE may have effects on "the liver, thyroid, and neurobehavioral development." [3] Voluntary and governmental actions [ edit ] PBDEs are found in a variety of consumer products, from TVs and toasters to mattresses and drapes. These chemicals are intended to slow the rate of ignition and fire growth, allowing people more time to escape from a fire or extinguish it. PBDEs affect a number of hormonal systems, including the androgen, progestin and estrogen systems, although the system most strongly affected by PBDEs is the thyroid hormone system. [9] Researchers in China measured 14 different PBDEs in fat tissues of women with breast cancer as well women without the disease. In addition to these concerning PBDE-related effects on human health, another serious worry is their neurotoxicity and potential roles in the etiology of neurodevelopmental disorders.

Commercial products consist predominantly of penta-, octa-, and decabromodiphenyl ether mixtures, and global PBDE production is about 40,000 tons per year. PBDE Toxicology (selected, mostly rats & mice, depends on congener) endocrine disruption thyroid anti-androgen (OH-metabolites?) developmental neurotoxicology reproductive effects ovarian changes decreased sperm, epididymis weight delayed puberty Some effects seen at levels not that different from those found in some people. (PBDE-47 and -99 are each major constituents of commercial PBDE mixtures used widely in North America.) These effects were persistent and became more pronounced as the mice aged [Eriksson 2001 and 2002]. The chemicals -- called polybrominated diphenyl ethers, or PBDEs -- are everywhere: in your TV, your computer, your toaster and your sofa. They've been in use since the 1970s. What are the health effects of PBDEs? Animal studies have shown that PBDE exposure during pregnancy and after birth caused problems with brain development in offspring.

Few human data are available on health effects of individual PBDEs. Of the three commercial mixtures, pentaBDE seems to show toxicological effects at the lowest concentration.

classification is required for any health or environmental hazard. Based on DINP risk assessment: PBDE substances have been phased. Polybromerad difenyleter (PBDE) är ett vanligt flamskyddsmedel som används för att minska risken för brand i en mängd olika produkter, till exempel Vidare överskrider halterna av flamskyddsmedel (PBDE) kraftigt gällande MKN i fisk vid alla sta- tioner där högsta halterna Exponering för höga halter kan leda till ökad risk för bröst- och biomarkers of animal health status.

There is no definite information on health effects of PBDEs in people. Rats and mice that ate food with moderate amounts of PBDEs for a few days had effects on the thyroid gland. Those that ate smaller amounts for weeks or months had effects on the thyroid and the liver. Large differences in effects are seen between highly-brominated and less

PCB, OCP, PBDE) can be related to negative health effects.
