“…TBBPA is likely to reach the marine environment largely through industrial waste waters from landbased industrial activities, and coastal areas worldwide are subjected to increasing TBBPA contamination, thus raising great environmental concern (Gu et al, 2019). Levels of TBBPA in urbanized coastal areas range from ng to µg in both sediments (g −1 dw) and waters (L -1 ) (Liu et al, 2016;Sühring et al, 2015;Gong et al, 2017 and refs therein).…”

Tetrabromobisphenol A-TBBPA, a widely used brominated flame retardant detected in aquatic environments, is considered a potential endocrine disruptor-ED for its reproductive/developmental effects in vertebrates. In aquatic invertebrates, the modes of action of most EDs are largely unknown, due to partial knowledge of the mechanisms controlling neuroendocrine functions.In the marine bivalve Mytilus galloprovincialis, TBBPA has been previously shown to affect larval development in the 48 hours larval toxicity assay at environmental concentrations. In this work, the effects of TBBPA were further investigated at different times post-fertilization. TBBPA, from 1 µg/L, affected shell biogenesis at 48 hours post fertilization-hpf, as shown by phenotypic and SEM analysis.The mechanisms of action of TBBPA were investigated at concentrations of the same order of magnitude as those found in highly polluted coastal areas (10 µg/L). At 28-32 hpf, TBBPA significantly affected deposition of both the organic matrix and CaCO3 in the shell. TBBPA also altered expression of shell-related genes from 24 to 48 hpf, in particular of tyrosinase, a key enzyme in shell matrix remodeling. At earlier stages (24 hpf), TBBPA affected the development of dopaminergic, serotoninergic and GABAergic systems, as shown by in situ hybridization-ISH and immunocytochemistry. These data contribute draw adverse outcome pathways-AOPs, where TBBPA affects the synthesis of neutrotransmitters involved in key events (neurodevelopment and shell biogenesis), resulting in phenotypic changes on individuals (delayed or arrested development) that might lead to detrimental consequences on populations.

“…The existence of product (d) confirmed the occurrence of debromination, scission, and deprotonation in the biodegradation of TBBPA, while the product (f) confirmed the existence of oxidative pathways. And previous studies have demonstrated that TBBPA could undergo β-scission to form a cationic intermediate, and then hydroxylation [21,34,35]. To the best of our knowledge, product (d) has not been reported as an intermediate product of TBBPA by a fungus, but its analogs were identified in the biodegradation of TBBPA by Sphingomonas via cleavage and deprotonation [17].…”

The study investigated the characteristics of aerobic degradation of tetrabromobisphenol A (TBBPA) by Irpex lacteus F17 (I. lacteus F17) under four different cometabolic substrates (phenol, glucose, sodium pyruvate, and sodium citrate). The biodegradation of TBBPA by I. lacteus F17 could be enhanced via cometabolism, and glucose (8 g/L) was confirmed to be the optimum carbon source. For different initial solution pH ranging from 3.0 to 8.0, the results showed that I. lacteus F17 could be applied to biodegrade TBBPA in a wide pH range of 4.0-8.0, and the degradation rate could reach the maximum 75.31%, while the debromination rate reached the maximum 12.40% under pH 5.0. In addition, it has been confirmed that Mn 2+ (50 μmol/L) could promote the secretion of manganese peroxidase and TBBPA biodegradation efficiency. Seven intermediates were identified by gas chromatography-mass spectrometry analysis, and the possible degradation pathways were proposed, which indicated the biodegradation of TBBPA might be subjected to debromination, β-scission, hydroxylation, deprotonation, and oxidation reactions.

“…So far, only a few published reports on aerobic biotransformation of TBBPA and mainly focused on freshwater sediment, river sediment, activated sludge, and soil [5,16,17]. Previous studies presented rst evidence for aerobic TBBPA biodegradation in terrestrial settings, whereas there is limited study on degradation this compound and community-level changes in the coastal marine environment [7].…”

Coastal wetlands are subjected to increasing tetrabromobisphenol A (TBBPA) pollution, whereas knowledge on TBBPA degradation in marine environments is lacking. The changes of bacterial communities in TBBPA-polluted soil covered with halophytes were investigated. TBBPA could be degraded in the halophyte covered saline-alkali soil in microcosm experiment. Higher TBBPA removal occurred in the soil of Kandelia obovata compared with soils covered with Suaeda australis and Phragmites australis within 56 days of cultivation. The rhizosphere soils of S. australis, P. australis, and K. obovata mainly involved the classes of Bacteroidia, Gammaproteobacteria, Alphaproteobacteria, and Anaerolineae. Additionally, manganese oxidation, aerobic anoxygenic phototrophy, and fermentation funcitions were higher in the rhizosphere soil of K. obovata after TBBPA addition. This study indicated that the vegetation type is a vital factor in uencing the biodegradation mechanism of TBBPA and other related organic pollutants in salt marsh ecosystem.
