Data suggest that debromination, physical or metabolic removal of bromine atoms, may convert decaBDE to more toxic PBDE congeners, contributing further to the potential risk from exposure to these congeners. 2015-03-14 2005-08-24 2015-01-31 In animal studies, PBDE exposure has been associated with increased death of cerebellar granule cells, alterations in neuronal arachidonic acid release, and disruption of … 2017-07-19 margin of exposure (MOE) was used to determine the health risk of dietary PBDE exposure in different population groups. The MOEs for the majority of the population groups assessed were around or above 10,000.

How can PBDE exposure be reduced? Although the contribution to daily intake of PBDEs from a computer classroom is unknown, school authorities may wish to reduce exposures as much as possible. One of the most effective methods to reduce PBDE exposure in a classroom environment is to remove or replace old electronic equipment, furniture, and carpets. PBDE exposures that occur during infancy and childhood may impair brain maturation, particularly with respect to executive function, as it has been shown to have a continued developmental course through adolescence (Anderson et al., 2001a). Human exposure may occur through ingestion of foods or dust containing PBDEs.

Traces of PBDEs have been detected in samples of human tissue, human blood and breast milk (EPA 2009; He and others 2006) According to EPA, evidence of carcinogenic potential is suggested for decaBDE (EPA 2009; EPA IRIS 2008).

We conducted a systematic review and meta-analysis to summarize available peer-reviewed data of prenatal PBDE exposure effects on cognitive function, motor function, and behavior problems in children. Eligible birth cohort NIEHS grantees report that prenatal exposure to polybrominated diphenyl ethers (PBDEs) used as flame retardants are associated with attention problems in children 3 to 7 years old. This is one of the first studies to examine prenatal PBDE exposure effects on both preschool and school age development. Live well, live longer. New research offers more evidence that the mantra rings true: People who got regular PBDE Exposure.
