Passive sampling of PAHs and some trace organic - GUPEA

Methods: Using female Sprague-Dawley rats exposed to low-dose PBDE-47 (0.1, 1.0 and 10 mg/kg/day) from pre-pregnancy until weaning of offspring to mimic human exposure, we investigated the effects 4 Effect of Polybrominated Diphenyl Ethers on Neurodevelopment. Polybrominated diphenyl ethers (PBDEs) are a class of brominated hydrocarbons that have been used as flame retardants in a variety of products, such as textiles, plastics, electronic materials, and polyurethane foams for furniture ().The class is comprised of 209 congeners that share a brominated diphenyl ether molecule with up to Effects of polybrominated diphenyl ethers on thyroid hormone, neurodevelopment and fertility in rodents and humans. Czerska M(1), Zieliński M, Kamińska J, Ligocka D. Author information: (1)Department of Toxicology and Carcinogenesis, Nofer Institute of Occupational Medicine, Łódź, Poland, m … 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. A substantial amount of work has been done, surveying the potential association of PBDE exposures with behavioral deficits in humans, as well as in other animal models. Furthermore, several regional studies have shown increasing concentrations in human milk, tissue, and serum samples, with the most prevalent PBDE congeners in human samples being PBDE-47 and PBDE-99. Therefore, the widespread uses of PBDEs and increased amount of contamination in the environment have led to rising concern about the possible adverse health effects in humans.

Pbde effects on humans

have been found in biota and human breast milk. In the present study we assessed the effects of developmental exposure to one of the most persistent PBDE congeners (PBDE-99) on juvenile basal motor activity levels and adult male reproductive health. Wistar rat dams were treated by gav- Few effects were observed for PBDE parent congeners, while inhibition of depolarization-evoked Ca 2+ increases by OH-PBDEs was mostly associated with preceding increases in basal Ca 2+ due to Ca 2+ release from intracellular stores (Dingemans et al., 2010b). Future exposure studies involving canine models should take into account toxicokinetic parameters, such as absorption, bioaccumulation, metabolism, and excretion, in order to provide a better understanding of the relationship between PBDE and PCB exposure and adverse effects on animals and humans. Environmental Quality Standard (EQS) for biota, where human health is considered the most critical for PBDEs and therefore is defined for edible parts of fish.

Various PBDEs have also been studied for ecotoxicity in mammals, birds, fish, and invertebrates. adverse effects in humans from PBDE expo-sure.

PBB, in plastics and textiles.

In recent years, PBDEs have generated international concern over their widespread distribution in the environment, their potential to bioaccumulate in humans and wildlife, and their suspected adverse human health effects. Exposure of human breast cancer cells to BDE-47, one of the most common PBDEs found in people’s bodies, led to an increase in oxidative stress, a process that has been associated with increased risk for breast cancer. PBDEs may affect both estrogen and thyroid hormone processes in ways that could increase the risk of breast cancer., There is no definite information on health effects of PBDEs in people. Rats and mice that ate food with moderate amounts of PBDEs for a few days had effects on the thyroid gland.

They have been used in many consumer and industrial products since the 1970s, to decrease the ability of materials to ignite. In rats and mice exposed to PBDE disturbances in thyroid hormone homeostasis and reproductive system such as changes in reproductive organs weight and disorders in sperm motility and motion were found.

Tetra-, penta- and hexa-BDEs are the congeners most commonly found in humans. Recent concerns on possible adverse health effects of PBDEs are focusing on their potential endocrine disrupting Effects on humans and the environment. Flame retardants can be released from their host materials and thereby contaminate indoor air quality.

Environmental 7 Mar 2006 While extrapolations from effects in laboratory animals to humans entail a range of uncertainties, these data suggest that PBDE levels currently 19 Apr 2013 However, it does not automatically follow that PBDEs are causing harmful effects in humans.

Tox Town, from the National Library of Medicine, provides consumer-level information on toxic chemicals in everyday places and situations, potential health effects, and ways to reduce the risk. “PBDE serum levels 4-7-fold higher than other cats in their subgroup (Figure 2). Owing to this within-group variability, the mean “PBDE serum concentrations in young, non-HT, and HT cats were not significantly different (p)0.34).
