Neontatal exposure to deca-brominated diphenyl ether PBDE 209

Previous research suggested a link between PBDE exposure and preterm birth, but those studies focused on exposure to the chemicals late in pregnancy, specifically among white and African American mothers. We measured PBDEs in maternal blood and assessed IQ for 592 3-year-old children. •. Prenatal PBDE exposure was related to lower IQ scores, but only among 6 Feb 2018 Evidence suggests prenatal polybrominated diphenyl ethers (PBDE) exposure effects on human neurodevelopment, but this is controversial Each of these is a source of human exposure to PBDEs. In this study, we attempted to model PBDEs concentrations in various typical indoor environments on Although human data on health effects are still lacking for PBDEs, ample data on toxicity are available from animal studies. 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.

(Chao 2007) significant proportion of future exposure following release to outdoors, and subsequent incorporation into the food supply Danger is that we have yet to see peak in dietary exposures Urgent need to manage “end-of-life” of the current vast indoor reservoir of PBDE-containing goods Meta-analysis of human studies (n = 4 studies, 595 children) for PBDE exposure (represented as congener BDE-47, lipid-adjusted) measured in cord blood or maternal serum during gestation or at birth for IQ outcome (FSIQ or McCarthy Scale) assessed in children between 48–84 months: reported effect estimates [95% confidence interval (CI)] from individual studies (inverse-variance weighted, represented by size of rectangle) and overall pooled estimate from random effects (RE) model per 10-fold 2012-11-15 · Evidence of adverse human health effects from PBDE exposure has been steadily building over the past decade. Other CHAMACOS studies have also revealed links between flame retardant concentrations in mothers’ blood and decreased fertility , lower birthweight babies and changes in thyroid hormone levels , even after controlling for exposure to pesticides and other environmental chemicals. PBDEs have been detected in household dust, 25 food, and in air drawn from a warm TV, 26 but the major human exposure pathways have yet to be identified. PBDEs with fewer bromines, such as penta, have the highest potential for bioaccumulation and are typically the most common classes found in humans, fish and other wildlife.

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. Human exposure to PBDEs is thought to result from dietary sources, including fish, fatty foods, and mother’s milk.

polybrominated diphenyl ether — Svenska översättning

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. Human exposure to PBDEs is thought to result from dietary sources, including fish, fatty foods, and mother’s milk. However, oral ingestion from dust and leachates may be a larger source (Sjodin et al., 2008 a), particularly for children (Jones-Otazo et al., 2005; Stapleton et al., 2005).
