Temporal Trends of Brominated Flame Retardants and Other Emerging POPs in Waters around East Asia: Retrospective Studies Using Archived Samples from es-Bank, Ehime University, Japan
Introduction Brominated flame retardants (BFRs) are a group of compounds that are added to a wide range of products, such as printed circuit boards, computer cases, electronic appliances, automobiles and construction materials to prevent the outbreak of fire. Among them, additive flame retardants like polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecanes (HBCDs) are the focus of cu...
متن کاملRecent Developments in Halogen Free Flame Retardants for Epoxy Resins for Electrical and Electronic Applications
The recent implementation of new environmental legislations led to a change in the manufacturing of composites that has repercussions on printed wiring boards (PWB). This in turn led to alternate processing methods (e.g., lead-free soldering), which affected the required physical and chemical properties of the additives used to impart flame retardancy. This review will discuss the latest advanc...
متن کاملAssessing oestrogenic effects of brominated flame retardants hexabromocyclododecane and tetrabromobisphenol A on MCF-7 cells.
Tetrabromobisphenol A (TBBPA) is the main flame retardant used in printed circuit boards and laminates. The human population is highly exposed to TBBPA as it is used in consumer electronics as well as office and communication equipment. The main use of hexabromocyclododecane (HBCD) is in insulation foam boards, which are widely used in the construction sector. Brominated flame retardants may po...
متن کاملAn ADME Study with 2,2',4,4',-Tetrabromodiphenyl ether (BDE-47) in Chickens
Polybrominated diphenyl ethers (PBDEs) are synthesized in large quantities and are used as flame retardants in textiles and electronic equipment, especially in computer circuit boards. Due to their structural similarity to polychlorinated dibenzo-p-dioxins and biphenyls, their environmental persistence, and a growing database of toxicological effects, this class of compounds has become a new en...
