“…Tetrabromobisphenol A (TBBPA) is one of the most widely used brominated flame retardants which is designed to improve the fire safety of plastic paints, synthetic textiles, electrical devices, or other materials [1][2][3]. TBBPA is ubiquitous and can be found in many environmental compartments such as the hydrosphere, soil, sewage sludge, sediments, and house dust [3,4]. It could also occur in the biosolids or discharge of wastewater treatment plans if such plans could not treat TBBPA efficiently [5,6].…”

“…This could be one of the entry points for TBBPA to enter the food chain and ultimately reach consumers due to its bioaccumulative property. Indeed, TBBPA has been found in food items or human biological samples [3,4,7,8]. Many studies have reported negative effects of TBBPA on the health of aquatic organisms, mammals, and human beings, such as affecting cellular signalling pathways and levels of thyroid hormones and causing immunotoxicity or neurotoxicity [1,7].…”

TBBPA is known as a potential endocrine disruptor and a source of oxidative stress in a wide variety of organisms [9] due to its weak estrogen-like properties and being a precursor to bisphenol A (BPA) [3,10].…”

This study proposed a sequential redox process to partially degrade tetrabromobisphenol A (TBBPA) within a reactor to a great extent. After 72 hours in an anoxic environment, 20 ppm of TBBPA could be effectively degraded by sulfurized zerovalent iron nanoparticles (S-nZVI) at concentrations of 2 g L-1 and 4 g L-1. Biphenol A (BPA) together with tri-, di-, and monobromobisphenol A was detected by high-performance liquid chromatography (HPLC) suggesting that TBBPA was debrominated by S-nZVI in a stepwise manner. Following the S-nZVI treatment, a persulfate-advanced oxidation process (PS-AOP) system with persulfate concentrations varied from 5 to 20 mM was incorporated to degrade the final debrominated byproduct, BPA, for 2 hours. The two-stage anoxic/oxic reactions at the same reactor with initial conditions (0.037 mM TBBPA, 4 g L-1 of S-nZVI, pH 6 in anoxic stage, 20 mM of PS in the latter oxic stage) were investigated. The sulfurized layer played an important role in such a system and hypothetically contributes to increasing electron transfer from Fe0 core as well as hydrophobicity of the NP surface. It was demonstrated that the S-nZVI/PS-AOP system could effectively remediate TBBPA and BPA and consequently provide a promising strategy to remedy brominated organic pollutants in the environment.

“…There is evidence of association with particles and bioaccumulation (Howard and Muir, 2010;Liu et al, 2016). TBBPA is now detectable in environmental media such as soil (Lu et al, 2018;Sun et al, 2014), dust (Barghi et al, 2017), sediment (Cheng and Hua, 2018), water (Chokwe et al, 2017), aquatic organisms (Ashizuka et al, 2008;de Jourdan et al, 2013), human being blood (Lu et al, 2017) and breast milk (Antignac et al, 2009;Shi et al, 2009). Highly industrialized countries were observed relatively high TBBPA levels in environmental monitoring such as China, Germany, Japan, Korea, the UK and the USA (Abdallah et al, 2008;Fromme et al, 2014;Wang et al, 2015).…”

Tetrabromobisphenol A (TBBPA) is the largest brominated flame retardant which can be released to environment and cause long-term hazard. In this work, we developed a rapid and highly sensitive fluorescence enzyme-linked immunosorbent assay (FELISA) for monitoring of TBBPA in soil samples. TBBPA specific nanobody derived from camelid was fused with alkaline phosphatase to obtain the bi-functional fusion protein, which enable the specific binding of TBBPA and the generation of detection signal simultaneously. The assay showed an IC 50 of 0.23 ng g −1 , limit detection of 0.05 ng g −1 and linear range from 0.1 to 0.55 ng g −1 for TBBPA in soil samples. Due to the high resistance to organic solvents of the fusion protein, a simple pretreatment by using 40% dimethyl sulfoxide (DMSO) as extract solvent can eliminate matrix effect and obtain good recoveries (ranging from 93.4% to 112.4%) for spiked soil samples. Good relationship between the results of the proposed FELISA and that of liquid chromatography tandem mass spectrometry (LC-MS/MS) was obtained, which indicated it could be a powerful analytical tool for determination of TBBPA to monitor human and environmental exposure.

Summar y A simultaneous determination method for brominated flame retardants (BFRs) of hexabromocyclododecane isomers (HBCDs), tetrabromobisphenol A (TBBPA) and 2,4,6-tribromophenol (TBP) in road dust has developed and applied to the environmental distribution survey in Nagoya city. The recovery rates and relative standard deviations (RSD%) of total HBCDs, TBBPA, TBP were 86% (RSD 2.3%), 107% (RSD 1.3%) and 114% (RSD 4.2%), respectively. The method was applied to the determination of the BFRs in road dusts at 50 area meshes (2.5 km ×2.5 km) covering the entirety of Nagoya city. The concentrations of total HBCDs, TBBPA and TBP in the road dust were respectively 0.11 to 10.6 ng/g with the mode value of 1.2 ng/g or less, 0.77 to 120 ng/g with the mode of 2.4 to 7.2 ng/g and 0.64 to 147 ng/g with the mode of 2.8 to 8.4 ng/g. There were no relationships among correlation of the three BFRs, which suggests that the BFRs would be individually emitted from different sources to air with the discrimination of HBCDs isomers.
