Mineralization and Primary Biodegradation of Organophosphorus Flame Retardants in Activated Sludge
Halogen-free flame retardants (HFFRs), such as the aromatic organophosphorus flame retardants (OPFRs) triphenyl phosphate (TPP), resorcinol bis(diphenylphosphate) (RDP) and bisphenol A bis(diphenylphosphate) (BDP) have been proposed as potential replacements for brominated flame retardants in polymers and textiles. Although these OPFRs are already marketed, their environmental fate and effects ...
متن کاملRecent Developments in Organophosphorus Flame Retardants Containing P-C Bond and Their Applications
Organophosphorus compounds containing P-C bonds are increasingly developed as flame retardant additives due to their excellent thermal and hydrolytic stability and ease of synthesis. The latest development (since 2010) in organophosphorus flame retardants containing P-C bonds summarized in this review. In this review, we have broadly classified such phosphorus compounds based on the carbon unit...
متن کاملOrganophosphorus Flame Retardants Inhibit Specific Liver Carboxylesterases and Cause Serum Hypertriglyceridemia
Humans are prevalently exposed to organophosphorus flame retardants (OPFRs) contained in consumer products and electronics, though their toxicological effects and mechanisms remain poorly understood. We show here that OPFRs inhibit specific liver carboxylesterases (Ces) and cause altered hepatic lipid metabolism. Ablation of the OPFR target Ces1g has been previously linked to dyslipidemia in mi...
متن کاملUPLC-MS/MS Determination of Organophosphorus Flame Retardants and Ultraviolet Absorbers in River Water and STP Effluent Samples
A sensitive, selective and rapid method for the analysis of organophosphorus flame retardants (OPFRs) and ultraviolet absorbers (UVAs) in river water and STP effluent samples by solid-phase extraction (SPE) with ultra-performance liquid chromatography tandem mass spectrometry (UPLCMS/MS) was developed. It allows the determination of 8 OPFRs and 6 UVAs. A single SPE consisting on the loading 200...
متن کاملEnvironmental Impact of Flame Retardants (Persistence and Biodegradability)
Flame-retardants (FR) are a group of anthropogenic environmental contaminants used at relatively high concentrations in many applications. Currently, the largest market group of FRs is the brominated flame retardants (BFRs). Many of the BFRs are considered toxic, persistent and bioaccumulative. Bioremediation of contaminated water, soil and sediments is a possible solution for the problem. Howe...
