EPA is concerned that certain PBDE congeners are persistent, bioaccumulative, and toxic to both humans and the environment. The critical endpoint of concern for human health is neurobehavioral effects. Various PBDEs have also been studied for ecotoxicity in mammals, birds, fish, and invertebrates. brominated congeners of PBDE tend to bioaccumulate more than higher brominated congeners. Exposure in rats and mice caused thyroid hormone bioactivity, neuro-developmental toxicity and other symptoms.

This report provides a comprehensive assessment of the exposure of Americans to this class of persistent organic pollutants.

Animal studies also found that PBDEs can alter thyroid and other hormone levels. PBDEs are ubiquitous in the environment, and, according to the EPA, exposure may pose health risks. According to U.S. EPA's Integrated Risk Information System, evidence indicates that PBDEs may possess liver toxicity, thyroid toxicity, and neurodevelopmental toxicity.

These studies document that PBDEs Children with higher prenatal exposure to PBDEs have been found in several studies to have lower IQ. Exposure has also been linked to hyperactivity, poor Human exposure may occur through ingestion of foods or dust containing PBDEs . 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.

The population groups with comparatively high dietary exposures EPA announced the availability of the final report, An Exposure Assessment of Polybrominated Diphenyl Ethers. This report provides a comprehensive assessment of the exposure of Americans to this class of persistent organic pollutants. 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. 2011-08-26 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.

Human exposure may occur through ingestion of foods or dust containing PBDEs. Inadvertent dust ingestion may be a particularly important source of PBDE exposure among toddlers, who spend a lot of time on the ground and are far more likely to put their hands in their mouths than older children and adults.

Harley, Kim *; Concentrations of 10 PBDE congeners were measured in serum collected from the women near the end of the second trimester of pregnancy using gas chromatography and isotope dilution high resolution mass spectrometry. 2018-02-06 Epidemiological data regarding PBDE exposure and child health are limited.
