DekaBDE - en rapport från ett regeringsuppdrag

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).

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 Evidence suggests prenatal polybrominated diphenyl ethers (PBDE) exposure effects on human neurodevelopment, but this is controversial due to conflicting research results. We conducted a systematic review and meta-analysis to summarize available peer-reviewed data of prenatal PBDE exposure effects on cognitive function, motor function, and behavior problems in children. Eligible birth cohort NIEHS grantees report that prenatal exposure to polybrominated diphenyl ethers (PBDEs) used as flame retardants are associated with attention problems in children 3 to 7 years old. This is one of the first studies to examine prenatal PBDE exposure effects on both preschool and school age development.

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. 2009-07-01 Animal studies have shown that PBDE exposure during pregnancy and after birth caused problems with brain development in offspring.

A few studies report an association between PBDE exposure and lower birth weight, height, head and chest circumferences (Chao et al., 2010b ), and reduced fecundability (Harley et al., 2010). 4.3.3 Cancers There is not enough scientific evidence to confirm whether o r not PBDE exposure increases cancer risk in humans.

2016-05-01 PBDE Exposure. Primary PBDE exposure routes for humans have been identified as indoor air and dust, diet, and breast milk and in utero transmission. Indoor Air and Dust. Many studies identify indoor air and the concomitant inhalation, ingestion, or dermal absorption of PBDEs present in household dust as a primary PBDE exposure pathway for PBDE exposures vary from country to country, as illustrated by the results of the various international biomonitoring and environmental sampling data available. Harrad and Porter (2007) first reported on blood serum PBDE levels in New PBDE exposures from the trade-data based diet (origin-speciﬁc measures) were found to be very close to the median exposures of 0.68 ng/kg bw/day for the Swiss population, indicating that the per Developmental PBDE Exposure and IQ/ADHD in Childhood: A Systematic Review and Meta-analysis Juleen Lam,1 Bruce P. Lanphear,2 David Bellinger,3 Daniel A. Axelrad,4 Jennifer McPartland,5 Patrice Sutton,1 Lisette Davidson,6 Natalyn Daniels,1 Saunak Sen,7 and Tracey J. Woodruff1 1Program on Reproductive Health and the Environment, University of California, San Francisco, San Francisco, … 2018-08-01 2017-05-26 Pre- and/or postnatal exposure to PBDEs may cause long-lasting behavioral abnormalities, particularly on motor activity and cognition. 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 the toxic effects of PBDEs. 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.

In an investigation led by an NYU Long Island 2020-06-03 · Polybrominated diphenyl ether (PBDE) exposures have been associated with adverse pregnancy outcomes. A hypothesized mechanism is via alterations in placental development and function.

New research offers more evidence that the mantra rings true: People who got regular PBDE Exposure. Primary PBDE exposure routes for humans have been identified as indoor air and dust, diet, and breast milk and in utero transmission. Indoor Air and Dust. Many studies identify indoor air and the concomitant inhalation, ingestion, or dermal absorption of PBDEs present in household dust as a primary PBDE exposure pathway for • exposure to PBDEs started in the 1970s, hence the oldest population has received relatively low PBDE exposure • PBDEs have half-lives in the body that are substantially shorter compared to other persistent organic pollutants.

However, studies examining postnatal PBDE exposures and inattention and impulsivity have been inconsistent. 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.

According to EPA, evidence of carcinogenic potential is suggested for decaBDE. Detection methods include gas chromatography, mass The concentrations of PBDEs in human blood, breast milk, and body fat indicate that most people are exposed to PBDEs. You may be exposed to PBDEs through household dust, consumer products, and from residues in food. PBDEs are ubiquitous in the environment, and, according to the EPA, exposure may pose health risks.
