Human Exposure to Polychlorinated Biphenyls and Polybrominated Biphenyls [PDF]

open access: yesEnvironmental Health Perspectives, 1978
Although the polychlorinated biphenyls (PCBs) have been used in a wide variety of industrial applications in the U. S. from 1930 until 1970, when their distribution was voluntarily restricted to closed systems, there is scant information on human exposure to adverse human health effects in the U. S. In the U.

Bromine–lithium exchange: An efficient tool in the modular construction of biaryl ligands

open access: yesBeilstein Journal of Organic Chemistry, 2011
Regioselective bromine–lithium exchange reactions on polybrominated biaryls enable the modular synthesis of various polysubstituted biphenyls such as bis(dialkylphosphino)-, bis(diarylphosphino)- and dialkyl(diaryl)phosphinobiphenyls. All permutations of

Recent developments in the analysis of polybrominated diphenyl ethers and polybrominated biphenyls in plastic

open access: yesReviews in Analytical Chemistry, 2016
Polybrominated diphenyl ethers (PBDEs) and polybrominated biphenyls (PBBs), heavily used as flame retardant in plastics, are harmful to environment and human health. It is of great importance for method development to determine PBDEs and PBBs in plastics.

Association between several persistent organic pollutants and thyroid hormone levels in serum among the pregnant women of Korea

open access: yesEnvironment International, 2013
Persistent organic pollutants such as polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and organochlorine pesticides (OCPs) are of global concern because of their widespread contamination and adverse health effects.

Human developmental toxicity mechanism of polybrominated biphenyl exposure and health risk regulation strategy for special populations

open access: yesEcotoxicology and Environmental Safety, 2022
Polybrominated biphenyls (PBBs) can bioaccumulate in nature and are toxic to humans. Long-time exposure to PBBs in pregnant women can lead to the birth of an infant with abnormal conditions.

Perfluoroalkyl substances and thyroid function in older adults

open access: yesEnvironment International, 2015
Current understanding of the thyroid disruptive properties of perfluoroalkyl substances (PFASs), particularly in aging populations, is limited. The objectives of this study were to (i) assess associations between thyroid function, as measured by serum ...

Analysis of Polychlorinated Biphenyls and Polybrominated Biphenyl Ethers in Rice and Their Risk Assessment

open access: yesLiang you shipin ke-ji, 2023
The risk of polychlorinated biphenyls (PCBs) and polybrominated biphenyl ethers (PBDEs) in 45 rice samples was assessed. The rice samples were collected and ground, and all ground samples were treated according to the direct extraction-acidic silica ...

Menstrual function among women exposed to polybrominated biphenyls: A follow-up prevalence study

open access: yesEnvironmental Health, 2005
Background Alteration in menstrual cycle function is suggested among rhesus monkeys and humans exposed to polybrominated biphenyls (PBBs) and structurally similar polychlorinated biphenyls (PCBs).

Evaluating the Endocrine‐Disrupting and Oxidative Stress Potential of a 50‐Component Human‐Relevant Complex Chemical Mixture Using In Vitro Tests

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Humans are chronically exposed to mixtures of environmental contaminants. Exposure to endocrine‐disrupting chemicals (EDCs) contributes to increased health impairment observed globally. This study aimed to evaluate the endocrine‐disruptive and oxidative stress potential of a human‐relevant, complex chemical mixture in vitro.

Concentrations of Polychlorinated Biphenyls (PCBs), Polychlorinated Dibenzo-pdioxins and Furans (PCDD/Fs), and Polybrominated Diphenyl Ethers (PBDEs) as Functions of Sample Depth in Killer Whale (Orcinus orca) Blubber

open access: yesJournal of Applied Sciences and Environmental Management, 2010
Concentrations of polychlorinated biphenyls (PCBs), polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), and polybrominated diphenyl ethers (PBDEs) were examined as a function of depth in killer whale (Orcinus orca) blubber samples.
