Bisphenol A (BPA), a well-known environmental endocrine disruptor, has been implicated in anxiety-like behavior. But the neural mechanism remains elusive. Herein, we found that mice exposed to 0.5 mg/kg/day BPA chronically from postnatal days (PND) 21 to PND 80 exhibited depression- and anxiety-like behavior. Further study showed that medial prefrontal cortex (mPFC), was associated with BPA-induced depression- and anxiety-like behavior, as evidenced by decreased c-fos expression in mPFC of BPA-exposed mice. Both the morphology and function of glutamatergic neurons (also called pyramidal neurons) in mPFC of mice were impaired following BPA exposure, characterized by reduced primary branches, weakened calcium signal, and decreased mEPSC frequency. Importantly, optogenetic activation of the pyramidal neurons in mPFC greatly reversed BPA-induced depression- and anxiety-like behavior in mice. Furthermore, we reported that microglial activation in mPFC of mice may also have a role in BPA-induced depression- and anxiety-like behavior. Taken together, the results indicated that mPFC is the brain region that is greatly damaged by BPA exposure and is associated with BPA-induced depression- and anxiety-like behavior. The study thus provides new insights into BPA-induced neurotoxicity and behavioral changes.

Graphical Ni/Fe bimetallic atom cluster catalyst is prepared by a hydrothermal to stimulate PMS to produce high concentration 1 O 2 and efficiently remove BPA from aqueous solution. It is found that 1 O 2 in the system is the most important active component in the degradation process of BPA, and a high concentration of 1 O 2 could promote the rapid degradation of BPA in solution. The advanced oxidation process based on peroxymonosulfate (PMS) is a new water purification strategy. In this work, Ni/Fe bimetallic atom cluster composite catalyst is prepared by a hydrothermal synthesis to stimulate PMS to produce high concentration singlet oxygen ( 1 O 2 ) and efficiently remove bisphenol A (BPA) from aqueous solution. The experimental data show that in a broad pH range (pH=3–11), the removal rate of BPA by the non-free radical pathway induced by 1 O 2 is close to 100 %, and the catalyst still has high stability after 5 cycles. The mechanism of BPA removal in NiFe−BC/PMS/BPA catalytic degradation system is investigated by quenching experiment. It is found that 1 O 2 in the system is the most important active component in the degradation process of BPA, and a high concentration of 1 O 2 could promote the rapid degradation of BPA in solution. In this paper, the high catalytic activity and selectivity of bimetallic atomic cluster catalysts can provide new insights for the treatment of phenolic wastewater.

Bisphenol A (BPA) and diisobutyl (DIBP) phthalate are widely used as typical plasticizers in food packaging. Plasticizers can be released from polymers, migrate into food, and be ingested by humans, leading to various health problems. However, little research has investigated the combined toxicity of BPA and DIBP, particularly their intestinal toxicity. Our goal is to analyse the combined toxicity of BPA (50 mg/kg) and DIBP (500 mg/kg) on the intestines of KM mice. Additionally, we tried to find natural products that can inhibit or prevent the combined toxicity of BPA and DIBP. The results indicated that the combination of BPA and DIBP exposure resulted in a reduction of beneficial flora, an increase in D-Lac levels (136 ± 14 μmol/L), an increase in intestinal permeability, activation of the notch pathway, and a decline in intestinal stem cells (ISCs) to goblet cells, compared to single-exposure sources. Nevertheless,Rubus chingiiHu phenolic extract (RHPE) (200, 400 and 600 mg/kg) ameliorated the BPA and DIBP-induced intestinal microbiota disruption and intestinal mucosal barrier impairment by inhibiting the overactivation of the notch pathway. The results of this study highlight the potential risks to human health posed by the combination of BPA and DIBP and may help explain the potential pathways of enterotoxicity caused by combined ingestion.

Glasses such as automobile windshields, mirrors, and lampshades are prone to fogging due to temperature changes, which affects the process of use and even jeopardizes safety. Hydrophilic films can prevent the glass surface from fogging by absorbing condensation droplets. However, the anti-fog film only lasts for a short period because it will gradually dissolve with the moisture increasing, which leads to image distortion. Herein, we propose a hydrophilic/hydrophobic coating to achieve longer anti-fog persistence. The strong interface bonding of the polymer is the key to improving the durability performance of the coating. It prevents interfacial failure and folding caused by fogging conditions. In this paper, a multifunctional coating with good anti-fog and anti-frost properties was prepared using butyl acrylate (BA), acrylic acid (AA) and 4-benzoylphenyl acrylate (BPA) as the polymer monomers . The light transmission of coated glass is up to 90 % even under harsh fogging conditions. The poly(AA- co -BA-co-BPA) can be firmly bonded with the plasma-treated glass plate, which greatly enhances the durability and water resistance of the coating. After being immersed in deionized water for 60 h at room temperature, the coated glass still has a certain anti-fog effect and the light transmittance is maintained at about 85 %. In addition, the anti-fog coating has excellent self-healing properties due to the fact that the carboxyl group in AA can generate hydrogen bonding , so that it can be healed within 15 s with the help of hot water after physical damage. This anti-fog coating has great potential for application in construction, shipbuilding and other industries.

Bisphenol A (BPA) is a typical endocrine disrupting chemical widely distributed in the environment and in food systems. The adverse effects of BPA on reproductive health have posed major concerns worldwide. The aim of this study was to determine the potential of epigallocatechin gallate (EGCG) to protect against BPA-induced male reproductive toxicity and investigate the underlying protective mechanism. The protective effects of EGCG on BPA-induced reproductive toxicity were investigated using male zebrafish model. The results showed that EGCG alleviated BPA-induced developmental toxicity of F1 generation of zebrafish, reversed testis disorder and combated the blood-testis barrier (BTB) damage caused by BPA in zebrafish. In order to unravel the underlying mechanism, TM4 cell - constructed BTB model was used for further study. The results indicated that EGCG counteracted the damage induced by BPA on the integrity of BTB model and reduced the autophagy caused by BPA. Furthermore, EGCG effectively inhibited the BPA-induced upregulation of the expression level of AMPK (p-AMPKα/AMPKα), significantly restored the BPA-mediated downregulation of the expression levels o。f p-mTOR/mTOR, p-AKT/AKT and Raptor. The results suggested that EGCG mitigated the BPA-induced male reproductive toxicity through maintaining the integrity of BTB by inhibiting the autophagy mediated by AMPK/AKT/mTOR signaling pathway. This study provided a strategy for combating the BPA-induced reproductive toxicity using a well-known bioactive component as a potential therapeutic approach.

Bisphenol A (BPA) and its analogs are endocrine-disrupting chemicals that are frequently detected in environmental and human samples. However, the effective removal of BPA and its analogs has not yet been extensively studied. Herein, we introduce a novel enzyme reactor for the degradation of BPA and its analogs in water. The influence of pore size on the degradation efficiency of immobilized laccase in the spatial nanopores of hydrogel was investigated using BPA as a representative compound. This showed that nanopores enhance the activity of immobilized laccases in a pore size-dependent manner and increase their stability. Compared with the same amount of free laccase, the 50 mg/L BPA degradation performance of laccase immobilized in 76 nm nanopores increased to 300 %. Taking advantage of magnetic separation, this immobilized laccase can be reused, and its degradation capacity was maintained at over 73.7 % after ten reactions. Moreover, the degradation of seven BPA analogs was 1.03–5.88 times higher using laccase immobilized in nanopores compared with free laccase. Also, the biocatalyst could efficiently degrade BPA analogs in real water matrix. This study opens up a new avenue for the removal of BPA and its analogs by immobilizing laccase in nanopores, overcoming the key limitations introduced by the short enzyme life span and non-reusability.

Bisphenol A (BPA) analogues, used in a range of products due to health concerns regarding BPA, have emerged as ubiquitous environmental contaminants worldwide. This study aims to evaluate the levels of nine bisphenols (BPs) and eight biomarkers (malondialdehyde, MDA; 8-hydroxy-2′-deoxyguanosine, 8-OHdG; estradiol, E2; follicle-stimulating hormone, FSH; luteinizing hormone, LH; complement compound 3, C3; immunoglobulin M, IgM and c-reaction protein, CRP) in human serum (n = 353) to explore their potential relationships. The detection rates (DRs) of eight BPs in serum samples taken from people working in a dense industrial area of Shenzhen (Guangdong Province, China) were over 72% except for bisphenol B (BPB) (DR = 27.5%). The mean concentrations of BPA, bisphenol P (BPP), BPB, bisphenol F (BPF), bisphenol FL (BPFL), 4,4′-dihydroxy-benzophenone (DHBP), bisphenol AF (BPAF), 4,4′-thiodiphenol (TDP) and bisphenol S (BPS) were 42.062, 2.083, 0.765, 0.578, 0.423, 0.402, 0.191, 0.120, and 0.071 ng/mL, respectively. BPA and BPFL were significantly correlated with the level of oxidative stress indices MDA and 8-OHdG; BPAF, BPB, and DHBP were strongly correlated with the level of endocrine disturbance indices E2, FSH, and LH; and BPF, DHBP, and BPAF were apparently related to the level of immune interference indices C3 and IgM. This study also suggests multiple impacts (oxidative stress, endocrine disturbance, and immune interference) mediated by BPs contaminants in vivo. To our knowledge, this is the first study to report the correlations among these nine serum BPs and oxidative stress and endocrine and immune system indices in human serum samples collected from dense industrial areas.

The levels of three phenolic endocrine-disrupting compounds (EDCs), NP, BPA and 4-t-OP were determined in water and sediment collected from sites along the Xiangjiang River, Zunyi, China. The NP, BPA and 4-t-OP concentrations ranged from 18.02 to 311.79 ng/L in the surface water, 16.04–408.12 ng/L in the submerged water, and 21.13–892.37 μg/kg dw in the sediment. NP contamination was most severe in both the river water and sediment. The ranges of the three phenolic EDCs were slightly greater in the submerged water than in the surface water ( p > 0.05). The concentrations in the middle reaches were greater than those in the upstream and downstream reaches in both the water and sediment, and significant differences in content were detected in some reaches. The levels of three phenolic EDCs in the water and sediment had a positive correlation. In addition, the distribution coefficient (K d ) indicated that NP was more likely to adsorb to the sediment, and BPA and 4-t-OP were more likely to adsorb to river water. Moreover, the risk quotient (RQ) and hazard quotients (HQ) were used to reveal the environmental and health risks caused by coexposure to the three phenolic pollutants. The results showed that the current pollution is a threat to the environment of the study area and not a threat to the health of the local population.

The efficient activation of peroxydisulfate (PDS) for wastewater treatment remains a great challenge. Photocatalysis, which generates highly-reactive electrons and holes, shows great potential in activating PDS for effective degradation and deep mineralization. Herein, an electron-enriched PDI-SiO 2 photocatalyst was synthesized by covalently linking 3,4,9,10-perylene tetracarboxylic dianhydride (PTCDA) onto silicon dioxide (SiO 2 ) to form π-π stacked supramolecular PDI layers for efficient PDS activation. The highly dispersed PDI generates electron-enriched PDI· - under visible light, promoting the rapid activation of PDS for bisphenol A (BPA) degradation. The PDI-SiO 2 activated PDS system realized a high BPA degradation rate of 0.100 min −1 and a remarkable mineralization rate of 81%. Moreover, the charge separation efficiency is significantly improved since the electrons of PDI· - are captured by PDS, boosting oxidative degradation and improving the mineralization efficiency. This work developed a novel PDS activation strategy by constructing electron-enriched photocatalyst, and revealed the mechanism of photocatalytic activation and deep mineralization.

Perovskite materials are reported to be effective in peroxymonosulfate (PMS) based Fenton-like reactions, the leaching rates of chalcogenide materials in perovskite materials are however serious, thus leading to bad performance in long-term stability. In this study, an O-doped MoS 2 is synthesized to composite with LaCoO 3 , and the high catalytic activity of LaCoO 3 is well preserved with greatly decreased Co leaching. During the BPA degradation with PMS as oxidant, ∼100% degradation can be achieved in 20 min and this degradation efficiency can be maintained for ∼45 h in a simulated fixed bed reactor, which is almost 3 times longer than the pure LaCoO 3 . With the compositing of O-doped MoS 2 , the leached Co was greatly decreased and the dominated reactive oxidation species (ROS) transformed from SO 4 •– into O 2 •– with longer lifespan, thus resulting in the better stability. This study could promote the application of perovskite materials in the real industrial wastewater treatment .

Bisphenol A (BPA) pollution poses an increasingly serious problem. BPA has been detected in a variety of environmental media and human tissues. Microbial degradation is an effective method of environmental BPA remediation. However, BPA is also biotoxic to microorganisms. In this study,Rhodococcus equiDSSKP-R-001 (R-001) was used to degrade BPA, and the effects of BPA on the growth metabolism, gene expression patterns, and toxicity-resistance mechanisms ofRhodococcus equiwere analyzed. The results showed that R-001 degraded 51.2% of 5 mg/L BPA and that 40 mg/L BPA was the maximum BPA concentration tolerated by strain R-001. Cytochrome P450 monooxygenase and multicopper oxidases played key roles in BPA degradation. However, BPA was toxic to strain R-001, exhibiting nonlinear inhibitory effects on the growth and metabolism of this bacterium. R-001 bacterial biomass, total protein content, and ATP content exhibited V-shaped trends as BPA concentration increased. The toxic effects of BPA included the downregulation of R-001 genes related to glycolysis/gluconeogenesis, pentose phosphate metabolism, and glyoxylate and dicarboxylate metabolism. Genes involved in aspects of the BPA-resistance response, such as base excision repair, osmoprotectant transport, iron-complex transport, and some energy metabolisms, were upregulated to mitigate the loss of energy associated with BPA exposure. This study helped to clarify the bacterial mechanisms involved in BPA biodegradation and toxicity resistance, and our results provide a theoretical basis for the application of strain R-001 in BPA pollution treatments.Keywords:Bisphenol A;Rhodococcus;biodegradation;toxicity resistance

Based on the low utilization rate of visible light and the high-charge carriers-recombination efficiency of bismuth oxybromide (BiOBr), in this work, noble metal Ag was used to modify BiOBr, and Ag-doped BiOBr nanoplates (Ag-BiOBr) were obtained through a one-step hydrothermal method. Compared with BiOBr, the absorption edge of Ag-BiOBr showed a redshift from 453 nm to 510 nm, and the absorption efficiency of visible light was, obviously, improved. Bisphenol A (BPA) was chosen as the target pollutant, to evaluate the photocatalytic performance of the samples. Ag0.1-BiOBr showed the highest degradation efficiency. The intrinsic photocatalytic activity of Ag0.1-BiOBr, under visible light, was approximately twice as high as that of BiOBr. In this way, a new visible-light-driven photocatalyst was proposed, to fight against organic pollution, which provides a promising strategy for water and wastewater treatment.Keywords:bismuth oxybromide (BiOBr);Ag-doping modification;visible light;charge separation;bisphenol A (BPA)
