Lai, Yiang published the artcilePotential application of BC₃ nanotube for removal of bisphenol from water; density functional theory study, Formula: C12H10O4S, the publication is Journal of Molecular Liquids (2022), 119147, database is CAplus.

Using d. functional theory, the current study reported stability, structures, inter-mol. forces, and the electronic characteristics in the solution of complexes which was formed between bisphenol S (BPS) and the BC₃ nanotube (BC₃NT). The potential application of BC₃NT in removing BPS was investigated. BPS had an interaction with B atom of BC₃NT with its S atom and the energy of adsorption was approx. -29.31 kcal/mol. The electronic characteristics of BC₃NT were significantly affected by BPS, which facilitated the adsorption process. Moreover, the donor-acceptor interaction mainly controlled the adsorption mechanism of BPS. In addition to promoting the development of sustainable and cheap heteroatom carbon-based materials (HCBMs), the current study systematically investigated the adsorption mechanism of HCBMs for BPS.

Mok, Sori published the artcileWithin- and between-person variability of urinary phthalate metabolites and bisphenol analogues over seven days: Considerations of biomonitoring study design, Related Products of alcohols-buliding-blocks, the publication is Environmental Research (2022), 112885, database is CAplus and MEDLINE.

Urine was used as a part of a human biomonitoring study based on the excretion kinetics of less-persistent contaminants, such as phthalates and bisphenol A (BPA). Despite the advantages of being non-invasive and easy to collect, urine can show a large variability of concentrations of phthalate metabolites and BPA within a person depending on sampling time. Therefore, it is essential to assess the variability of urinary concentrations for comprehensive sampling design in the context of exposure and risk assessments. In this study, 18 phthalate metabolites and eight BPs were measured in all spot urine (n = 401) collected from 12 participants for seven consecutive days to evaluate within- and between-person variabilities. The intraclass correlation coefficients (ICCs) for all spot urines were poor for monomethyl phthalate (ICC: 0.002) and BPA (0.121) but were moderate for monoethyl phthalate (0.514) and monobenzyl phthalate (0.462). Based on the results of di (2-ethylhexyl) phthalate (DEHP) metabolites, the half-life and differences in metabolic capability seem to affect the ICCs. Urinary mono (2-ethylhexyl) phthalate (MEHP), a primary metabolite of DEHP, was suggested as a short-term exposure marker of DEHP in our study. Creatinine- and sp. gr.-adjusted concentrations of phthalate metabolites and BPs resulted in increased ICCs, implying requirements for randomly collected spot urine. Most analytes in the first morning voids (FMVs) were correlated significantly with those in the daily composites, suggesting the feasibility of FMVs to estimate the daily exposure dose. This study facilitates a more comprehensive sampling design and data interpretation strategy for human biomonitoring studies.

Téteau, Ophélie published the artcileBisphenol S Alters the Steroidome in the Preovulatory Follicle, Oviduct Fluid and Plasma in Ewes With Contrasted Metabolic Status., Recommanded Product: 4,4′-Sulfonyldiphenol, the publication is Frontiers in endocrinology (2022), 892213, database is MEDLINE.

Bisphenol A (BPA), a plasticizer and endocrine disruptor, has been substituted by bisphenol S (BPS), a structural analogue that had already shown adverse effects on granulosa cell steroidogenesis. The objective of this study was to assess the effect of chronic exposure to BPS, a possible endocrine disruptor, on steroid hormones in the ovary, oviduct and plasma using the ewe as a model. Given the interaction between steroidogenesis and the metabolic status, the BPS effect was tested according to two diet groups. Eighty adult ewes were allotted to restricted (R) and well-fed (WF) groups, that were further subdivided into two subgroups. Ewes were exposed to 50 µg BPS/kg/day in their diet (R50 and WF50 groups) or were unexposed controls (R0 and WF0 groups). After at least 3 months of BPS exposure, preovulatory follicular fluid, oviduct fluid and plasma were collected and steroid hormones were analyzed by gas chromatography coupled with tandem mass spectrometry (GC-MS/MS). A deleterious effect of restricted diet on the volume of oviduct fluid and numbers of pre-ovulatory follicles was observed. Exposure to BPS impaired estradiol concentrations in both follicular and oviduct fluids of well-fed ewes and progesterone, estradiol and estrone concentrations in plasma of restricted ewes. In addition, a significant interaction between metabolic status and BPS exposure was observed for seven steroids, including estradiol. In conclusion, BPS acts in ewes as an endocrine disruptor with differential actions according to metabolic status.

Gao, Xiaozhong published the artcilePassive sampling hydrophilic and hydrophobic bisphenol analogues using hydrophilic-lipophilic balance sorbent-embedded cellulose acetate membrane in surface waters, SDS of cas: 80-09-1, the publication is Science of the Total Environment (2022), 156239, database is CAplus and MEDLINE.

Bisphenol analogs (BPs) are ubiquitous emerging contaminants in water environments and have wide polarity ranges (1.65 < log K_OW< 7.2). Integrated passive sampling strategy rarely contains hydrophilic and hydrophobic organics simultaneously, while the method has good application perspective in monitoring organic contaminants. This work evaluated passive sampling performance for fifteen BPs in a newly developed passive sampler, i.e., hydrophilic-lipophilic balance sorbent-embedded cellulose acetate membrane (HECAM). In the dynamic accumulation experiments, both hydrophilic and hydrophobic BPs (including moderately hydrophilic BPs) well followed first-order kinetic uptake in the HECAMs. The estimated uptake rate constants, elimination rate constants, and equilibrium partition coefficients for BPs ranged from 4.4 L g^-1 d^-1 to 14.7 L g^-1 d^-1, 0.22 d^-1 to 0.72 d^-1, and 3.99 to 4.64, resp. The kinetic parameters for BPs in HECAM show limited correlations to log K_OW values, which the rule differs from traditional passive sampler. In the study of elimination kinetics, three deuterium labeled compounds showed incomplete elimination in HECAM and did not follow first-order isotropic exchange kinetics. Dual sorption mechanisms including both adsorption and partition were found for chems. in HECAM, which the partitioned part could release to water and the adsorbed part could not easily release to water from HECAM. As a result, performance reference compounds (PRCs) calibration may be inapplicable to HLB sorbent-based passive sampler. The field deployment of HECAM in coastal waters of Guangdong, China resulted in the detection of eleven BPs, which indicated that the waters have been polluted by various BPs. Finally, monitoring strategy of simultaneous passive sampling hydrophobic and hydrophilic organic contaminants in surface waters was recommended.

Niu, Lijun published the artcileTuning the reactivity of permanganate by naturally occurring DNA bases: Enhanced efficiency of micropollutant abatement, Application In Synthesis of 80-09-1, the publication is Separation and Purification Technology (2022), 120654, database is CAplus.

The transformation of extracellular DNA (e.g., antibiotic resistance genes) in water has attracted increasing attention over the last decades. To date, the effect of the resulting byproducts (e.g., DNA bases) on the degradation of micropollutants by oxidants remains largely unknown. In this study, four DNA bases (i.e., deoxyadenosine (dA), deoxythymidine (dT), deoxycytidine (dC), and deoxyguanosine (dG)) were investigated as potential permanganate (Mn(VII)) activators for the oxidation of tetracycline (TC) in water. The dC exhibited the best performance, e.g., the first-order rate constant of TC increased from 0.082 min-1 in the absence of dC (i.e., Mn(VII) alone) to 0.290 min^-1 in the presence of 500μM dC (i.e., Mn(VII)/dC system). The degradation of three other emerging micopollutants (i.e., bisphenol F (BPF), bisphenol S (BPS), and methotrexate (MTX)) by Mn(VII)/dC was also greater than Mn(VII) alone. Multiple lines of evidence suggested that the synergistic effect of in-situ formed MnO2 colloids and Mn(VII) had a major role in the observed enhancement compared to radicals, Mn(VI), Mn(V) or Mn(III). The transformation products (TPs) of TC by Mn(VII) with and without dC were tentatively identified, from which the reaction pathways were proposed. Despite the high degradation of micropollutants by Mn(VII)/dC system, the majority of TPs were recalcitrant to biodegradation with multi-endpoint adverse health effects on different aquatic organisms, as indicated by in silico prediction software. Overall, this study unveiled the free DNA bases as in-situ Mn(VII) activators for removing emerging contaminants of global concern from water. However, the secondary environmental risks related to the TPs need to be considered in terms of water safety assessment.

Tan, Xuerong published the artcileDevelopment and Validation of a Modified QuEChERS Method for the Analysis of Bisphenols in Meats by UPLC-MS/MS, Recommanded Product: 4,4′-Sulfonyldiphenol, the publication is Chromatographia (2022), 85(5), 433-445, database is CAplus.

Abstract: A reliable and affordable QuEChERS (quick, easy, cheap, effective, rugged, and safe) methodol. in combination with ultra-high performance liquid chromatog.-tandem mass spectrometry (UPLC-MS/MS) was successfully developed and validated for the determination of eight bisphenols (BPs) residues containing in meats (chicken, duck, beef, pork, fish, shrimp, and mutton). A novel QuEChERS method optimization was carried out in terms of process efficiency (PE), matrix effect (ME), and extraction recovery (RE). After a simple vortex extraction of the samples with acetonitrile, 1 g sodium acetate was used for salting out (NaAC), and 100 mg primary secondary amine (PSA) purifying reagents were used for purification The properties of the sorbents were assessed by the obtained parameters, such as matrix effect (ME), linearity, sensitivity, accuracy, and precision. Under the optimal conditions, BPs were well separated on an ACQUITY UPLC BEH C₁₈ column in 8 min by gradient elution, and exhibited a good linear relationship (R² > 0.9988) in the linear range. Moreover, the limits of detection (LODs) and the limits of quantification (LOQs) were located in the range of 0.01- 0.11μg/kg and 0.03 – 0.37μg/kg, resp. The developed method was satisfactory in terms of accuracy (relative recoveries: 76.1% – 113.7%) and precision (relative standard deviations below 10.3%). Finally, the developed method was successfully employed to identify and quantify BPs residues in 28 real meat samples. The proposed QuEChERS-UPLC-MS/MS method is simple, high efficiency, cost-effective, practical, and susceptible to being implemented in routine laboratories to quickly detect the BPs in meats (chicken, duck, beef, pork, fish, shrimp, and mutton). In this sense, the method is useful for obtaining BPs residue data to evaluate the contamination status of BPs in meat food and provide scientific support for scientific supervision.

Jia, Yaya published the artcileZirconium dioxide@phosphazene for enhancing mechanical property, flame retardancy, and thermal property of polythiourethane composites, Application In Synthesis of 80-09-1, the publication is Journal of Applied Polymer Science (2022), 139(22), 52230, database is CAplus.

Introducing high strength inorganic nanoparticles has emerged as an effective strategy to optimize the comprehensive properties of polymers, but good dispersion must be maintained to avoid clustering of inorganic nanoparticles. We report a novel phosphazene-coated ZrO₂ nanoparticles (ZrO₂@PZS) prepared by a simple ultrasonic method to further enhance thermal, mech., optical properties and flame retardancy of polythiourethane (PTU). ZrO₂@PZS nanoparticles presented good dispersion in composites, with regular spherical core-shell structures exhibiting significant enhancement effects for overall performance of PTU composites, through strong interfacial interaction. Studies revealed that regular spherical ZrO₂@PZS strengthened thermal and tensile properties of PTU, which reached 62.8°C and 79.28 MPa resp. More importantly, PTU composites showed good flame retardancy through catalytic carbonization, condensed phase shielding and gas phase dilution effect of ZrO₂@PZS, where the limiting oxygen index was increased to 25.39% from 20.39%. Moreover, the peak heat release rate, total heat release and smoke production rate could be reduced by 23.5%, 27.7% and 40.0%, resp. In brief, PTU composites show excellent potential in high strength special fireproof lenses.

Jia, Yaya published the artcileEnhancing mechanical, thermal property and flame retardancy of optical polythiourethane with self-assembly phosphazene nanoparticles, Quality Control of 80-09-1, the publication is Polymer Composites (2022), 43(4), 2010-2021, database is CAplus.

Polythiourethane (PTU) has attracted considerable attention in engineering building materials. Here, based on phosphazene nanoparticles (PZS-1 and PZS-2) prepared by water-triggered and ultrasonic self-assembly method, phosphazene/polythiourethane (PZS/PTU) composites with excellent mech. strength, high flame retardancy and good transparency was obtained. Then, the comprehensive properties of both composites were evaluated, where PZS-2 endowed PTU with better overall performance. Due to the good dispersibility of PZS and its strengthed interfacial interaction with PTU matrix, both PZS significantly enhanced mech. and thermal property of PTU, where the tensile strength and glass transition temperature of PZS/PTU composites reached to 84.34 MPa and 59.94°C resp. More importantly, compared to pure PTU, the values of peak heat release rate (HRR), total heat release rate (THR), smoke production rate (SPR), and total smoke production (TSP) of composites were decreased by 10.5%, 13.3%, 30.6% and 18.0%, resp. The limiting oxygen index of composites was improved to 21.39% due to the catalytic carbonization of PZS, the expanded carbon layer and the incombustible gases released during combustion. Meanwhile, the PZS/PTU composite exhibited the high refractive index of 1.6580 and good transparency (not less than 85% at 500 nm). The PZS/PTU composite was promising candidates for optical flame retardant coatings and engineering building materials.

Jorvekar, Sachin B. published the artcileDetermination of bisphenols and parabens in cow urine distillate from India: implication of human exposure and risk assessment, Recommanded Product: 4,4′-Sulfonyldiphenol, the publication is Environmental Science and Pollution Research (2022), 29(35), 52507-52519, database is CAplus and MEDLINE.

The exposures of a wide range of endocrine-disrupting chems. to cows have been linked to diseases and are a major concern. In Indian scripts, cow urine is believed to be a treatment for many diseases. Nonetheless, exposure of bisphenols and parabens to cow urine distillates is unknown. Hence, in this study, we determined the concentration of bisphenols and parabens in com. available cow urine distillate collected from India. The mean concentration of total bisphenols and parabens ranges from the limit of quantification (LOQ) to 149.3 ng/mL and 1479.88 ng/mL, resp. Predominant bisphenol-F and bisphenol-A were accounted for 88.6% and 6% of total bisphenol concentration, resp., in marketed cow urine distillate, whereas Me and Pr parabens were dominant and accounted for 33% and 65%, resp. The estimated mean daily intake (EDI) of bisphenol for males and females were 45.94 ng/kg-bw/day and 54.29 ng/kg-bw/day, resp., while for parabens EDI was 455.35ng/kg-bw/day and 538.14 ng/kg-bw/day for males and females, resp. Hazard quotient, to evaluate the potential risk of exposure, showed no risk in the studied samples. Even though the EDI results from the Monte-Carlo risk assessment anal. did not exceed the acceptable daily intake, their estrogenic actions cannot be ignored in general populations. The estrogenic activities contributed by parabens and bisphenol A measured by estradiol equivalency quotient (EEQ) ranged from 0.00033-42 pg/mL and 2.3 pg/mL, resp. Our results revealed higher concentrations of bisphenols and parabens in cow urine distillates; hence, special attention should be given to the quality and safety of cow urine distillates. Moreover, strict guidelines should be enforced for the quality of cow urine distillates.
