2019-10-7 · The contemporary PBDE was born. For the next 25 years, PBDE was the flame retardant of choice; virtually every product that contained polyurethane foam came with a brominated chemical. PBDEs, too, were banned at the federal level in 2005, but their presence in the environment and in older consumer products continues to be a public health concern.
No human studies have assessed the developing neurotoxicity of PBDEs. However, PBDEs in umbilical cord blood were associated with adverse birth outcomes, including lower birth weight and head circumference, as well as increased incidence of undescended testes. Two commercial PBDE mixtures, penta and octa PBDEs, were withdrawn from the market.
The present study shows that PBDE 209 can induce developmental neurobehavioural defects in both male and female mice. Neonatal exposure to PBDE 209 caused also increased susceptibility in adult mice to paraoxon and nicotine. All these effects 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 2020-05-01 Heavy metal induced effects on PBDE plant uptake are also plant specifics as shown for cadmium, where levels of up to 14,800 ng g DM-1 had no effect on BDE-209 uptake in case of black nightshade, but lifting effects in case of amaranth [75, 76]. Experimental studies in animals and epidemiological observations in humans suggest that PBDEs may be developmental neurotoxicants. Pre- and/or postnatal exposure to PBDEs may cause long-lasting behavioral abnormalities, particularly on motor activity and cognition. 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.

Medical Evaluation of PBDE exposure . PBDEs can be measured in human blood, body fat and breast milk for epidemiological studies.

In a Danish–Finish study the levels of PBDEs in breast milk were associated with cryptorchidism and increased serum LH (Main et al., 2007). Body systems affected by PBDE. PBDEs can concentrate in breast milk, body fat, and human blood.

In rodents, pre- and postnatal exposure to PBDE can cause neurobehavioral effects. Also in humans disturbances in thyroid hormone system, weight of reproductive organs and concentrations of sex hormones associated with PBDEs serum concentrations were found.
