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). Once absorbed, PBDEs distribute into body fat. Prenatal exposure to polybrominated diphenyl ethers (PBDEs) have been reported to impair executive function in children, but little is known whether childhood PBDE exposures play a role.

Prenatal exposure to polybrominated diphenyl ethers (PBDEs) have been reported to impair executive function in children, but little is known whether childhood PBDE exposures play a role. EPA is concerned that certain PBDE congeners are persistent, bioaccumulative, and toxic to both humans and the environment.

Environmental pollutants and alterations in the reproductive

These studies observed problems with learning, memory, and behavior in mice and rats. Animal studies also found that PBDEs can alter thyroid and other hormone levels. Human exposure may occur through ingestion of foods or dust containing PBDEs.

This paper is focused on reviewing the current status of PBDEs in the environment, as well as the critical adverse health effects based on the recent studies on … Background: Prenatal polybrominated diphenyl ether (PBDE) exposure has been associated with decrements in IQ and increased attention deficit/hyperactivity disorder related behaviors in children; however, data are limited for the role of postnatal exposures. 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). 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.

Thus, further investigations of this pathway are warranted. In addition, future studies should address how PBDE exposure affects viral replication. Place, publisher, year, edition, pages Conclusion: In this review, we propose that PBDE, and possibly other environmental exposures, during child development can induce or compound mitochondrial dysfunction, which in conjunction with a dysregulated antioxidant response, increase a child’s susceptibility of autism.

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 .
