Toward a more rigorous inspection of food contact materials, the importance of sample preparation for nontarget screening should be addressed. Direct immersion-solid-phase microextraction coupled to gas chromatography mass spectrometry (DI-SPME-GC-MS) was optimized for nontarget screening of migrants in 3% acetic acid, 10% ethanol, and 95% ethanol food simulants by response surface methodology (RSM) in the present study. Optimum conditions were DVB/CAR/PDMS fiber, no pH adjustment for 10% and 95% ethanol simulant but pH adjustment to 7 for 3% acetic acid simulant, no salt addition, 5 min preincubation, 55 min extraction at 70 degrees C, and 8 min desorption at 250 degrees C. In addition, 9.5 times dilution of 95% ethanol samples prior to extraction was required. pH modification of 3% acetic acid samples was found to be critical for the extraction of amines. The proposed methodology was then evaluated by determining the limit of detection (LOD) as well as repeatability of 35 food contact materials-related substances. Except for those amines and diols which have a relatively high LOD, the LODs of the rest of the substances were 0.1-14.1 mu g/kg with a precision of 1.9-23.0% in 10% ethanol and were 0.1-20.2 mu g/kg with a precision of 2.5-19.6% in 3% acetic acid simulant. The LOD and precision in 95% ethanol simulant were 0.7-163.7 mu g/kg and 1.4-26.8%, respectively. The proposed method can be applied for an overall screening of migrants from these three simulants at even trace levels, though attention should be paid to some specific analytes, e.g., diols and amines, which could have a high LOD and toxicity.

The lack of Nationally Certified Reference Materials for the calibration of DSC equipment in the sub-ambient range has been addressed by the introduction of a Certified Reference Material of purified cyclohexane by the National Metrology Institute of Japan. This sample, in conjunction with the CRM material phenyl salicylate and the ITS-90 fixed point material mercury, has enable a DSC-thermomicroscopy system to be accurately calibrated over the temperature range 90 degrees C to 50 degrees C. The DSC has then been used to measure values for the solid-solid transitions in the potential Certified Reference Materials ammonium sulphate, adamantane and ammonium dihydrogen phosphate, which have the advantage of being thermally stable and easy to handle, and for the melting point of diphenyl ether. In addition, the effect of temperature cycling on these materials has been investigated.

This paper describes the pyrolysis of Poplar fluff (from Populus alba) using on-line apparatus, and carbonization process at 850 degrees C using the fixed bed reactor. Characteristics of pyrolysis products were examined. Elemental and chemical analyses were shown that Poplar fluff has higher energy content characterized by increased content of fibrous structure (particularly cellulose). Independent parallel reactions model very well describes devolatilization process. It was found that increased amount of extractives can significantly affect on increased release of light gaseous products, but declining hydrocarbons, mostly the alkanes. Liquid product is mainly composed of phenolics, aldehydes, acids, esters and ketones. The carbonization process produces the great abundance of polycyclic aromatic hydrocarbons (PAH’s), where naphthalene is the most abundant. Mechanism for PAH’s formation was suggested. This study represents the first step in a much wider and more comprehensive way in thermal conversion processes of this type of fuel.

The crude electronic waste (e-waste) recycling has caused severe contamination of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in the local environment, begging the question of whether wildlife like birds living at e-waste sites are suffering from adverse effects. We examined several oxidative status markers and their relationships with hepatic concentrations of PCBs and PBDEs in common kingfisher (Alcedo atthis) that inhabit an e-waste site in South China. The results showed that the mean concentrations of Sigma PCBs (19100 ng/g) and Sigma PBDEs (507 ng/g) in kingfishers from e-waste site were several orders of magnitude higher than those in the species from a reference site. Correspondingly, hepatic concentrations of malondialdehyde (MDA) and reactive oxygen species (ROS) in kingfishers from the e-waste site were significantly higher than those detected in the reference population, suggesting oxidative distress in the birds breeding at the e-waste site. The activities of superoxide dismutase (SOD) and catalase (CAT) in the liver from the exposed group were significantly lower compared with the reference group, while the opposite trend was observed for glutathione peroxidase (GPx). Significantly positive correlations were observed between PCB or PBDE concentrations and the levels of MDA and ROS; while negative correlations were found for enzymatic activities of SOD and CAT. Overall, our results may suggest a potential linkage between exposure to e-waste-derived pollutants and elevated oxidative stress, thereby indicating a potential oxidative stress-related health effects in common kingfisher breeding at the e-waste site.

Pyridazinone analogues have been known to be potential candidates for anticonvulsant agents. We have identified several pyridazinone-based anticonvulsant agents. As a continuation to our previous research, a series of hybrid pyridazinone-thiazole connected through amide linkage were designed and synthesized. Among these, compound SP-5F demonstrated significant anticonvulsant activity with median effective dose of 24.38 mg/kg (MES) and 88.23 mg/kg (scPTz). Results of GABA estimation showed a marked increase in the GABA level when compared with control. Molecular docking studies at the active site of GABA receptor, further confirmed the GABA modulatory effects of SP-5F.

A new and sensitive method, termed magnetic solid phase extraction combined with dispersive liquid-liquid micro-extracton (MSPE-DLLME), has been developed for the simultaneous determination of biphenyl and biphenyl oxide in water samples. Different parameters influencing the extraction efficiency, including the amount of sorbent, sorption time, type of elution solvent and its volume, type of extraction solvent and its volume, and elution time were optimized. The calibration curves were linear in the range of 0.5-100 mu g/L for both of them. The limits of detection (LODs) were achieved, 0.03 mu g/L for biphenyl and 0.07 mu g/L for biphenyl oxide, respectively. Ultimately, the applicability of the method was successfully confirmed by the extraction and determination of biphenyl and biphenyl oxide in sea, river, tap, and water well.

Rationale Recently, we have reported a forced degradation study of a pharmaceutical drug regorafenib which contains a phenyl pyridyl ether derivative as building block. We observed interesting rearrangements in two of its degradation products in tandem mass spectrometry (MS/MS) experiments. As diphenyl ether derivatives are also molecular building blocks of biological importance and used as herbicides and flame retardants, we decided to investigate specifically the fragmentation behavior of these compounds along with phenyl pyridyl derivatives in detail using high-resolution electrospray ionization (ESI) MS/MS. Methods To understand the fragmentation reactions of protonated substituted diphenyl ethers and phenyl pyridyl ethers, ESI-MS/MS experiments were performed using a quadrupole time-of-flight (QTOF) mass spectrometer. Results In contrast to radical cations of diphenyl ether derivatives which do not eliminate CO, the [M + H](+) ions of substituted diphenyl ethers undergo rearrangement reactions after loss of neutral molecules (H2O, HCl, etc.) to form a bicyclic structure containing a keto group and do eliminate CO. Similar rearrangement followed by fragmentation was observed for protonated phenyl pyridyl ethers and the degradation products formed from regorafenib and sorafenib. Conclusions The protonated ions of substituted diphenyl ethers and phenyl pyridyl ethers on collision-induced dissociation have exhibited interesting rearrangement reactions, despite the nature of the substituent on both the aryl moieties. The proposed fragmentation patterns of these compounds give an insight into the understanding of gas-phase reactions in mass spectrometric studies of diphenyl ether and phenyl pyridyl ether derivatives.

Background: Polybrominated diphenyl ethers (PBDEs) are dangerous for the environment and human health because of their persistent organic pollutant (POP) characteristics, which have attracted extensive research attention. Raman spectroscopy is a simple highly sensitive detection operation. This study was performed to obtain environmentally friendly non-POP PBDE derivatives with simple detection-based molecular design and provide theoretical support for establishing enhanced Raman spectroscopic detection techniques. Methods: A three-dimensional quantitative structure-activity relationship (3DQSAR) pharmacophore model of characteristic PBDE Raman spectral was established using 20 and 10 PBDEs as training and test sets, respectively. Full-factor experimental design was used to modify representative commercial PBDEs, and their flame retardancy and POP characteristics were evaluated. Results: The pharmacophore model (Hypol) exhibited good predictive ability with the largest correlation coefficient (R-2) of 0.88, the smallest root mean square (RMS) value of 0.231, and total cost of 81.488 with a configuration value of 12.56 (<17).74 monosubstituted and disubstituted PBDE derivatives were obtained based on the Hypo 1 pharmacophore model and full-factor experimental design auxiliary. Twenty PBDE derivatives were screened, and their flame-retardant capabilities were enhanced and their migration and bio-concentration were reduced (log(K-OW) <5), with unchanged toxicity and high biodegradability. The Raman spectral intensities increased up to 380%. In addition, interference analysis of the Raman peaks by group frequency indicated that the 20 PBDE derivatives were easily detected with no interference in gaseous environments. Conclusion: Nine pharmacophore models were constructed in this study; Hypo 1 was the most accurate. Twenty PBDE derivatives showed Raman spectral intensities increased up to 380%; these were classified as new non-POP environmentally friendly flame retardants with low toxicity, low migration, good biodegradability, and low bio-concentrations. 2D QSAR analysis showed that the most positive Milliken charge and lowest occupied orbital energy were the main contributors to the PBDE Raman spectral intensities. Raman peak analysis revealed no interference between the derivatives in gaseous environments. Computed Properties of C12H10O.

China produces and consumes large quantities of brominated flame retardants (BFRs) as well as several other unregulated electronic waste recycling activities, causing high BFR concentrations in the natural environment. Thus, Traditional Chinese Medicines (TCMs) may be contaminated by legacy BFRs (e.g. polybrominated diphenyl ethers (PBDEs)) and emerging BFRs (eBERs, such as decabromodiphenyl ethane (DBDPE)) during growth, processing, packaging, and transportation. Pheretima, which is a typical animal drug recorded in Chinese Pharmacopoeia, was used as an example to evaluate human exposure to BFRs through TCM intake. This study is the first to determine 25 PBDEs and 5 eBERs in Pheretima and estimate the daily BFR intake via Pheretima-containing TCMs. Twenty-seven Shanghai Pheretima and fifty-one Guang Pheretima samples were collected between March and June 2019 in southeast China. High BFR detection frequencies were found in Pheretima, of which BDE-209 and DBDPE were the most predominant analytes. The total PBDE contents ranged from 73 pg/g to 8,725 pg/g, while that of the eBERs varied between 115 pg/g and 2,824 pg/g. The profiles and abundances were found to be species- and origin-dependent. However, the traditional processing of Pheretima may reduce BFR residues. Based on the usual clinical doses of Pheretima and the available chronic oral reference doses of BDE-47, 99, 153, and 209, the mean (95th percentile) of the total hazard quotient was estimated to be 9.1 x 10(-5) (2.7 x 10(-4)). Therefore, there is little risk related to BFR exposure for patients taking formulated Pheretima-containing TCMs. However, it is necessary to establish routine monitoring programs for the co-existence of pollutants in TCMs to perform a systematic and comprehensive risk assessment.

Molybdenum carbide (Mo2C) has emerged as a remarkable catalyst for the cleavage of the aromatic carbon-oxygen (C-aryl-O) and alkyl carbon-oxygen (C-alkyl-O) in lignin and lignin model compounds. However, the selectivity for the target product, that is phenol, is unsatisfactory due to the secondary alkylation reactions of the primarily produced phenol with the organic solvent used. Here, we report that a one-dimensional nitrogen-doped Mo2C catalyst (N-Mo2C@C) mediated from Mo-MOF via a pyrolysis-carbothermal reduction process shows a remarkably high selectivity toward phenol and monophenols in the valorization of aryl ethers and lignin because of its controllable phase composition and suitable valence state. The current study provides a method to develop efficient catalysts for lignin conversion into valuable chemicals.
