Following the restrictions on bisphenol A (BPA), the production and environmental release of bisphenol analogues (BPs) have increased. However, knowledge about the occurrence of bisphenol analogues other than BPA, especially in farmland soils and edible plants, remains limited. This study investigated the occurrence, contamination characteristics, and human health risks of eight bisphenol analogues in paired soil-plant samples from areas near factories in eastern China. Results indicated that the concentrations of Σ 8 BPs in the collected soil and plant samples ranged from 1.4 to 897.1 ng/g dw and 2.5 to 586.2 ng/g dw, respectively. BPA, bisphenol AF (BPAF), bisphenol F (BPF), and bisphenol S (BPS) were the primary components of BPs, with BPA having the highest detection frequency (74 %). In addition, a positive correlation was observed between the root concentration factor and the log K ow of BPs ( R 2 = 0.471, P < 0.05), whereas the translocation factor exhibited a negative correlation with the log K ow ( R 2 = 0.405, P < 0.05). The hazard index (HI) values of BPs in paired soil-plant samples were <1, suggesting that the current contamination levels of BPs in soils and plants are unlikely to pose significant health risks to humans. However, potential risks from long-term exposure require careful monitoring. This study offers new insights into the spatial distributions and contamination status of BPs in farmland soils and plants, highlighting the environmental behavior and health risks of other bisphenol analogues.

An extended one-step Stőber method was utilized for the preparation of core@shell spheres, which was made up of a thin layer of resorcinol-formaldehyde (RF) and a silica core. After the carbonization and template-removal process, hollow porous carbon spheres (HPCSs) were synthesized. The structure of HPCSs was characterized by scanning/transmission electron microscopy and N 2 adsorption/desorption isotherms, Fourier transform infrared spectroscopy, energy dispersive X-ray spectrometer and Raman spectroscopy. The results showed that the silica cores were removed successfully and the HPCSs were in good sphere shape with uniform size, high surface areas as well as pores hollow framework structure. Compared with MWCNTs and 3D-graphene, HPCSs exhibited superior extraction ability for nine bisphenols (BPs). HPCSs showed extremely outstanding extraction efficiency for BPs as well as high adsorption capacity due to its hollow porous structure. It was applied as sorbent for the enrichment of nine BPs from environmental water samples and soft drinks prior to high performance liquid chromatographic (HPLC) analysis, obtaining recoveries ranged from 89.6% to 111.5% and the relative standard deviations (RSD) from 0.8% to 6.3%, and the limits of quantification (LOQs) were in the range of 0.183–1.763 μg L −1 .

Bisphenols (BPs) can migrate from packaging materials into foods, resulting in potentially harmful residues. For example, accumulation of BPs is associated with endocrine disorders. Owing to matrix effects, development of an effective and eco-friendly sample pretreatment would be helpful for BPs detection in beverages packed in plastic containers. In this work, an extraction bar, composed of hollow fiber (HF) functionalized with covalent organic frameworks (COF@Tp-NDA) and 1-ocanol, was prepared for extraction of five BPs simultaneously. The synergistic effect of COF@Tp-NDA and 1-octanol improved the extraction efficiency of BPs from milk-based beverage, juice, and tea beverage. Under optimal conditions, limits of detection ranged from 0.10 to 2.00 ng mL −1 (R 2 ≥ 0.9974) and recoveries ranged from 70.1 % to 106.8 %. This method has the potential to enrich BPs, supporting their accurate determination in complex beverages.

A novel inorganic nonmetallic material boron carbide (B 4 C) was applied in paper spray ionization to analyze organic molecules in both negative and positive modes. The utilization of B 4 C has led to a notable enhancement in signal responses for various molecules, including bisphenols and drugs, by approximately two to four times. The limit of detection (LOD) of bisphenol AF and nilotinib standard solutions can reach 1 and 0.5 μg/mL, respectively. Moreover, linear relationships for bisphenol AF was established within the concentration range of 1–100 μg/mL, exhibiting strong correlation coefficients. Recovery experiments for BPAF in water samples from the inlet and outlet of a sewage treatment plant, conducted without any pretreatment, achieved a maximum recovery rate of 98.8% and an RSD below 9.78%.

Rationale Bisphenol A and its alternatives are widely used in common consumer products and are known as environmental endocrine disrupting chemicals. Five bisphenol analogues, namely, tetrabromobisphenol A (TBBPA), tetrachlorobisphenol A (TCBPA), 4,4′-sulfonyldiphenol (BPS), bisphenol A (BPA) and 4,4′-hexafluoroisopropylidenediphenol (BPAF), were selected to study their interactions with serum albumins, aiming at a better understanding of the toxicological mechanisms of bisphenol compounds. Methods The interactions between human and bovine serum albumins (HSA and BSA) with these five compounds were investigated by electrospray ionization mass spectrometry (ESI-MS). Fluorescence spectroscopy and molecular docking confirmed the ESI-MS observations and provided complementary information with respect to thermodynamic properties and binding modes. Results TBBPA showed the highest binding ability with HSA and BSA, followed by TBBPA and BPS, whereas BPA and BPAF exhibited little or no binding with these serum albumins. The calculated thermodynamic parameters suggested that hydrogen bonds and electrostatic forces played important roles for these interactions. Binding energies of TBBPA, TCBPA, and BPS calculated by molecular docking were −35.18, −34.39, and −25.89 kJ mol −1 , respectively, in good agreement with ESI-MS measurements. Conclusions The results of this study showed that halogenated substituents on the phenolic rings of bisphenol could enhance the binding ability with serum albumins. This work could provide useful information for further research on the relationship between molecular structures and toxicities of bisphenols. Copyright © 2016 John Wiley & Sons, Ltd.

Using high-performance liquid chromatography-mass spectrometry, fifteen bisphenols and halogenated phenols were simultaneously analyzed in tea for the first time in China. Response surface methodology was used to optimize sample preparation conditions based on QuEChERS. Finally, the limits of detection and the limits of quantification were 0.0200–0.173 μg/kg and 0.0892–0.770 μg/kg, respectively. The recoveries were 70 %–120 % for most compounds (except for some compounds at low spiked concentrations) with RSDs <20 %. Then 135 dried tea samples were analyzed. Bisphenol S, A and F were the predominant bisphenol contaminants with detection rates above 80 %, and the median level of bisphenol F (4.90 μg/kg) was even higher than that of bisphenol A (2.74 μg/kg). Bisphenol A ( p < 0.001) and bisphenol F ( p = 0.007) were significantly higher in black tea than in green tea. Hazard index was estimated and bisphenols in tea may pose potential risks to human health.

Core-shell structured magnetic covalent organic framework (Fe 3 O 4 @COF) nanospheres were rapidly synthesized at room temperature using the monodisperse Fe 3 O 4 nanoparticles (NPs) as magnetic core and benzene-1,3,5-tricarbaldehyde (BTA) and 3,3′-dihydroxybenzidine (DHBD) as two building blocks (denoted as Fe 3 O 4 @BTA-DHBD), respectively. They can serve as a mass spectrometry probe for rapid and high-throughput screening of bisphenols (BPs) from pharmaceuticals and personal care products (PPCPs) by surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS). The Fe 3 O 4 @BTA-DHBD nanospheres showed some superior features involving average pore size distribution (2.82 nm), high magnetization values (42.5 emu g −1 ), high specific surface area (82.96 m 2 g −1 ), and good chemical/thermal stability. It was used as both ideal adsorbent for enrichment of BPs and new substrate to assist ionization in SELDI-TOF-MS. The method exhibited good linearity in the range 0.05–4000 ng mL −1 with correlation coefficients ( r ) higher than 0.9920. Low limits of detection (LODs) (500 pg mL −1 for bisphenol A (BPA), 2 pg mL −1 for bisphenol B (BPB), 28 pg mL −1 for bisphenol C (BPC), 60 pg mL −1 for bisphenol F (BPF), 33 pg mL −1 for bisphenol AF (BPAF), 200 pg mL −1 for bisphenol BP (BPBP), 10 pg mL −1 for bisphenol S (BPS), 90 pg mL −1 for tetrabromobisphenol A (BPA(Br) 4 ), and 380 pg mL −1 for tetrabromobisphenol S (BPS(Br) 4 )) and good recoveries (80.6–115%) of BPs in PPCPs were achieved. The relative standard deviations (RSDs) of spot-to-spot ( n = 10) and sample-to-sample ( n = 5) were in the ranges 5–11% and 5–12%, respectively. The dual-function platform was successfully applied to the quantitative determination of BPs in PPCPs. It not only expanded the scope of the application of COFs but also provided an alternative strategy for the determination of hazardous compounds in PPCPs.

Herein, we investigated in detail the relationship between surface properties and extraction performance of virgin and amino-functionalized MIL-101s(Fe) for the extraction of 10 bisphenols (BPs) and their derivatives. These BPs were used as model contaminants due to their different hydroxyl groups and contrasting polarities. The differential sorption efficiencies for relatively polar BPs (BPF, BPE, BPA , BPB , BPZ, BPAP and BPP) lies in the formation of hydrogen-bonding between OH of target analytes and NH 2 of two MIL-101s(Fe). However, the surface properties of MIL-101(Fe) and NH 2 -MIL-101s(Fe), such as S BET and pore structure , determined the extraction recoveries for BPs derivatives (BADGE, BADGE·2H 2 O and BFDGE·2H 2 O) due to lack of OH in their molecular structures. NH 2 -MIL-101s(Fe) nanosorbent was successfully applied to the preconcentration/extraction of trace BPs and their derivatives by dispersive solid-phase extraction (DSPE) method. Following optimization of the main factors, recoveries for BPs ranged from 90.8 to 117.8% and their LODs were 0.016–0.131 μg L −1 in environmental waters. Experimental precisions based on relative standard deviations were 0.9–4.9% for intra-day and 1.3–7.6% for inter-day analyses, respectively. These findings provide important information on how to design and modify nanosorbents for highly efficient extraction of pollutants having contrasting polarities. Moreover, the newly developed NH 2 -MIL-101s(Fe)-based DSPE method has a good application prospect in pretreatment of trace pollutants in real-world waters.

In this work, β-cyclodextrin-functionalized magnetic graphene oxide (NiFe 2 O 4 @GO@β-CD) was synthesized and employed as magnetic solid-phase extraction adsorbent for the extraction of bisphenols before high performance liquid chromatography analysis. The modification of β-cyclodextrin could enhance the adsorption performance of NiFe 2 O 4 @GO@β-CD towards bisphenols through the host-guest interaction and hydrogen-bond interaction. Under the optimal conditions, good linearities between peak area and concentration of bisphenols (1 – 300 μg L −1 , r ≥ 0.9989) were obtained with the limits of detection (S/ N = 3) in the range of 0.050 – 0.10 μg L –1 . The recoveries of bisphenols in milk and milk packaging ranged from 78.0% to 101.6%. Moreover, NiFe 2 O 4 @GO@β-CD showed stable chemical properties and good reusability with the recoveries of bisphenols remained above 80.0% after 12 MSPE cycles. The adsorption characteristics of NiFe 2 O 4 @GO@β-CD towards bisphenols fitted well with the pseudo-second-order kinetic model and Langmuir model. The hydrogen-bond interaction, π-π interaction, host-guest interaction and electrostatic interaction between sorbent and bisphenols played important role during the adsorption process. The developed method showed potential applications for the analysis of trace bisphenols in milk and milk packaging.

Bisphenol compounds exist widely in the environment and pose potential hazards to the environment and human health, which has aroused widespread concern. Therefore, there is an urgent need for an efficient and sensitive analytical method to enrich and determine trace bisphenols in environmental samples. In this work, magnetic porous carbon (MPC) was synthesized by one-step pyrolysis combined with a solvothermal method for magnetic solid-phase extraction of bisphenols. The structural properties of MPC were characterized by field emission scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, and saturation magnetization analysis. Its adsorption properties were evaluated by adsorption kinetics and adsorption isotherm studies. By optimizing the magnetic solid-phase extraction and capillary electrophoresis separation conditions, a capillary electrophoresis separation and detection method for four bisphenols was successfully constructed. The results showed that the detection limits of the proposed method for the four bisphenols were 0.71–1.65 ng/mL, the intra-day and inter-day precisions were 2.27–4.03% and 2.93–4.42%, respectively, and the recoveries were 87.68%-108.0%. In addition, the MPC could be easily recycled and utilized, and even if the magnetic solid-phase extraction was repeated 5 times, the extraction efficiency could still be kept above 75%.

Plant accumulation of phenolic contaminants from agricultural soils can cause human health risks via the food chain. However, experimental and predictive information for plant uptake and accumulation of bisphenol congeners is lacking. In this study, the uptake, translocation, and accumulation of five bisphenols (BPs) in carrot and lettuce plants were investigated through hydroponic culture (duration of 168 h) and soil culture (duration of 42 days) systems. The results suggested a higher bioconcentration factor (BCF) of bisphenol AF (BPAF) in plants than that of the other four BPs. A positive correlation was found between the log BCF and the log K ow of BPs ( R 2 carrot = 0.987, R 2 lettuce = 0.801, P < 0.05), while the log (translocation factor) exhibited a negative correlation with the log K ow ( R 2 carrot = 0.957, R 2 lettuce = 0.960, P < 0.05). The results of molecular docking revealed that the lower binding energy of BPAF with glycosyltransferase, glutathione S-transferase, and cytochrome P450 (−4.34, −4.05, and −3.52 kcal/mol) would be responsible for its higher accumulation in plants. Based on the experimental data, an attention mechanism multi-layer perceptron (AM-MLP) model was developed to predict the BCF of eight untested BPs by machine learning, suggesting the relatively high BCF of bisphenol BP, bisphenol PH, and bisphenol TMC (BCF carrot = 1.37, 1.50, 1.03; BCF lettuce = 1.02, 0.98, 0.67). The prediction of BCF for ever-increasing varieties of BPs by machine learning would reduce repetitive experimental tests and save resources, providing scientific guidance for the production and application of BPs from the perspective of priority pollutants.

Glucose-derived carbon-decorated magnetic microspheres were synthesized by an easy hydrothermal carbonization method and used as a high-efficiency adsorbent to extract bisphenols in water and tea drinks. The as-prepared carbon-decorated magnetic microspheres had a well-defined core–shell structure with a shell thickness of about 5 nm. The microspheres possessed high saturation magnetization at 60.8 emu/g and excellent chemical stability in aqueous solution. The experimental parameters affecting the extraction efficiency, including extraction time, pH, adsorbent dosage, desorption solvents, desorption time, and solution volume were evaluated. Electrostatic and π–π interactions were the major driving forces during extraction. Overall, a new magnetic solid-phase extraction method of determining bisphenols was developed on the basis of as-prepared magnetic microspheres. The method had a wide linear range, low limits of detection (0.03–0.10 µg/L), and high recoveries (85.4–104.6%).
