Routes of potential human exposure to PBDEs are ingestion, inhalation or dermal contact (NTP 2014). 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). 2020-12-01 Exposure assessment studies have documented body burden levels in various populations and investigated contributors of human exposure. These studies suggest that PBDE exposures are not homogeneous across diverse groups. For example, recent studies have shown higher exposures among young children compared to adults . Exposure to PBDEs may occur in many situations in daily life: PBDEs can be found in air, water, soil, sediments, indoor dust, and food. Dietary intake was long considered the most important source of human exposure, but ingestion of dust may also contribute significantly, in particular for children.

Exposure to polybrominated diphenyl ethers (PBDEs) during fetal development may be associated with deficits in attention and impulse control. However, studies examining postnatal PBDE exposures and inattention and impulsivity have been inconsistent.

Inadvertent dust ingestion may be a particularly important source of PBDE Xianbao Liu, Hong Zhan, Xu Zeng, Chunfang Zhang, Dunjin Chen, "The PBDE- 209 Exposure during Pregnancy and Lactation Impairs Immune Function in Rats" In vivo studies have demonstrated that prenatal or neonatal exposure to polybrominated diphenyl ethers (PBDEs) causes developmental neurotoxicity. However Personnel associated with the manufacture of PBDE-containing products are exposed to highest levels of PBDEs. Bioaccumulation is of particular concern in such Experimental studies in animals and epidemiological observations in humans suggest that PBDEs may be developmental neurotoxicants.

Preliminary and relatively small human studies of PBDE exposure in early life (assessed as breastmilk or cord blood concentrations) observe associations with: Decreased birth weight and length, chest circumference and BMI in a study of 20 Taiwanese infants. (Chao 2007) 2021-03-26 In future analyses, we will examine predictors of PBDE exposure such as diet, breastfeeding history, consumer electronics use, BMI, time outside the United States, and housing quality. Conclusion: Findings suggest that Mexican-American children living in California are experiencing higher PBDE exposure from their environment compared to children sampled from the general US population and Mexico. Exposure to polybrominated diphenyl ethers (PBDEs) during fetal development may be associated with deficits in attention and impulse control.

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. The population groups with comparatively high dietary exposures EPA announced the availability of the final report, An Exposure Assessment of Polybrominated Diphenyl Ethers.

Individual chapters in this document address: the production, use, and lifecycle of PBDEs; environmental fate; environmental levels; and human exposure. 2021-03-15 Further, neonatal exposure to PBDE 209 can cause persistent defects in memory and learning in adult male mice as well as increased levels of important neuroproteins CaMKII, GAP-43, synaptophysin and tau in adult male and female mice.

In the present study, we assessed the treatment effects of PBDE-209 administration on the immune function in rats during pregnancy and lactation. We harvested the blood and organs for flow cytometry, viability assay, enzyme-linked immunosorbent assay, and histological evaluation. The results of this study were the PBDE-209 exposure during pregnancy and lactation impairs immune function in rats
