2017-6-29 · In this study, we estimated human exposure to polybrominated diphenyl ethers (PBDEs), hexabromocyclododecanes (HBCDDs), and several emerging flame retardants (EFRs) via inhalation and dust ingestion. Sixty indoor stationary air samples, 13 personal air samples, and 60 settled dust samples were collected from a Norwegian cohort during winter 2013.

Inhalation of halogenated flame-retardants (HFRs) released from consumer products is an important route of exposure. However, not all airborne HFRs are respirable, and thus interact with vascular membranes within the gas exchange (alveolar) region of the …

Indoor settled dust particles are considered as an important source of human exposure to chemicals such as organophosphate flame retardants (PFRs). In recent decades the Kingdom of Saudi Arabia (KSA) has experienced tremendous growth in population, as …

absorption of flame retardants is poorly understood. Therefore, in the current project, we will investigate the NBFRs’ way from materials to the resulting internal human exposure. This includes: a) emissions from flame retardant materials b) levels in house dust c) levels in human breast milk d) dermal absorption, using a human skin model

2019-2-5 · Human Exposure to Brominated Flame Retardants and Reproductive Health by Paula Ingrid Johnson Chair: John D. Meeker Brominated flame retardants (BFRs) such as polybrominated diphenyl ethers (PBDEs) and other compounds are used in the manufacture of a variety of materials and consumer products to meet fire safety standards.

2017-9-22 · As flame retardants are not chemically bound to the products, they can easily leach into the environment and result in widespread human exposure, especially in the home environment.

2016-9-19 · Flame retardants (FRs) are commonly added to construction ... human exposure to PFRs.3,13,28,33,34 The presence of FRs on hands could be linked to exposure via dermal absorption and hand-to-mouth transmission,2,28,35,36 but information about transport of on-skin PFR is still limited. So far, it is still unclear

Flame retardants, advertised to decrease the ability of materials to ignite and cause harm to humans, have been added to a range of products since the 1960s. ... It is globally the most highly produced brominated flame retardant, with human exposure to it widespread. It has been found in human tissue and household dust, as well as other places ...

Indoor dust ingestion is one of the main pathways for human exposure to organophosphate flame retardants (PFRs). The urinary concentrations of diesters (DAPs) are usually used as biomarkers to assess human exposure to PFRs. In this study, the PFR and DAP levels were measured in morning and evening urine samp

We hypothesized that exposures to organophosphate (OP) flame-retardants can alter DNA methylation in human sperm cells affecting offspring's health. Sperm and urine samples were collected from 67 men in North Carolina, USA.

2009-2-27 · The main goal with this thesis is to assess work related human exposure to brominated flame retardants (BFRs), particularly polybrominated diphenyl ethers (PBDEs), in different work settings in Sweden. Also, a short review on BFRs in general, human exposure to BFRs and a presentation of analytical methodology of analysis of BFRs, is given.
