Brominated Flame Retardant Chemicals Science Essay
We assessed the exposure of the Flemish population to brominated flame retardants (BFRs) and perfluorinated compounds (PFCs) by analyzing collected umbilical cord blood, serum from adolescents and adults, and breast milk. Levels of polybrominated diphenyl ethers (PBDEs) in blood 6-6. g lipid weight, lw and milk 0-6. g lw, brominated flame retardants BFR are bromine-based organic compounds used as flame retardants. These compounds reduce the flammability and flame propagation of combustible materials such as plastics and textiles. Alcock et al. 2011 Yogui and Sericano, 2009. There are variants of BFR, each. Flame retardants are chemicals added to materials to slow or prevent the onset or growth of fire. Flame retardants have since been used in many consumer and industrial products. You can be exposed to flame retardants in several ways: Dust. House dust is one of the main ways people are exposed to these chemicals. 1 Introduction. Polybrominated diphenyl ethers PBDEs, which were formerly among the most widely used brominated flame retardants (BFRs), have been commercially manufactured from building materials, plastics, polyurethane foams, furniture, textiles, and electronics. Alaee et al. 2003. This is a methodological framework for the assessment of additives, brominated flame retardants, heavy metals and tracers of common flame retardants and fillers in mixed plastic output fractions from mechanical batch processing of large household appliances, LHA and refrigerators and freezers CFA by chemical analysis and density. The brominated organophosphate, tris-2,3-dibromopropyl phosphate Tris, was a flame retardant used in children's sleepwear when it was discontinued due to studies showing it to be a potent mutagen. We report concentrations of brominated flame retardants (BFRs), plastic samples from new and second-hand children's toys sourced from Great Britain previously shown by XRF to be Br positive. The results strengthen existing evidence that the recycling of BFR-treated electronic plastics has led to the accidental release. Brominated flame retardants BFRs belong to a growing class of compounds known as organohalogens, most of which are very persistent in the environment. Kodavanti and Loganathan, 2012, Kodavanti and Loganathan, 2014, Kodavanti et al. 2014. BFRs are currently the largest group of flame retardants marketed. The environmental aspects of the use of the flame retardants themselves, of the flame retardant products and of their recycling are of particular importance. As such, industry and research institutions are actively pursuing effective alternatives to many BFR compounds that can be manufactured economically and exhibit a wide range of BFRs. Since s, brominated flame retardants BFRs have been used in a wide variety of polymer and plastic applications that are widely used in modern society. These compounds play an important role in saving lives in the event of fire by reducing or inhibiting the burning process after its onset and prolonging the time of exposure to an environmentally relevant mixture of brominated flame retardants in utero and during lactation causes premature development of the fire. Mammary glands. Toxicological Sciences, 2021 179 2. Flame Retardants FRs are considered ED and include a diverse group of chemicals, such as bromine, chlorine, or phosphorus. Since s, these compounds have been applied in a wide range of commercial materials with the aim of reducing their flammability, Frederiksen et al. 1.,
