High-throughput screening of new psychoactive substances and related compounds in food by UHPLC-Q/Orbitrap
Article
作者: Huang, Xia ; Wan, Yuping ; Shi, Peiyu ; Wu, Wenlin ; Xiao, Quanwei ; Liu, Shiyao ; Guo, Tianrong ; Chen, Xiaoqi ; Zhou, Yan ; Xia, Bing ; Zhang, Min
Currently, there is concern about food products to which new psychoactive substances (NPS) have been added illegally. However, rapid, high-sensitivity, and high-throughput screening methods for such harmful substances have not been reported yet. In this study, a high-throughput non-targeted screening strategy was developed based on UHPLC-Q/Orbitrap. First, optimized pretreatment methods for typical high-risk matrices were established. Second, an accurate, efficient, and scalable high resolution mass spectrometry database containing 206 NPS and related compounds was constructed. The fragmentation pathways of three different types of fentanyl-related compounds were then systematically investigated to enhance compound identification. Additionally, a non-targeted screening strategy was developed using warning ions derived from 24 fentanyl-related compounds, streamlining the identification of NPS. This strategy was applied to 100 food samples with possible illegal additives and demonstrated its effectiveness. In summary, this study provides robust technical support for regulatory authorities in combating the illegal addition of food products.

Determination of Sedative and Anesthetic Drug Residues in Aquatic Food Products Using Solid Phase Extraction (SPE) and Liquid Chromatography–Tandem Mass Spectrometry (LC–MS/MS)
作者: Xia, Ning ; Wang, Li ; Liang, Feiyan ; Li, Minglu ; Chen, Yun ; Xin, Lina
The residues of sedative and anesthetic drugs in aquatic products are an important factor affecting food safety.In order to screen the residues of sedative and anesthesia drugs in aquatic products, a rapid and sensitive method was established using solid phase extraction (SPE) and high-performance liquid chromatog.-tandem mass spectrometry (HPLC-MS/MS).The samples were extracted by 80% aqueous acetonitrile by an alumina column and separated by a C18 column.The mass spectra were determined in pos. ion mode.The standard curves were matrix matched and quantified by the external standard method.The results showed that the linear ranges of the drugs in aquatic products were from 0.5 to 100 μg kg-1.The correlation coefficient (R2) was greater than 0.990 and the detection limits were between 0.001 and 0.322 μg kg-1.The average recovery rate and relative standard deviation were between 78.64% and 112.15% and from 0.41%-8.26%.Overall, the developed method showed promising results for the simultaneous qual. and quant. determination of the drug residues in aquatic products.

Fate and transformation of psychotropic drugs in urban wastewater systems and receiving rivers via the integration of targeted and suspect screening analysis

Psychotropic drugs rank among the most prescribed pharmaceuticals in the world. The ubiquitous occurrence of psychotropic drugs in the environment evoked rising concerns due to their various toxic effect on non-target organisms at low concentrations. However, the removal, transformation, and discharging of these drugs throughout wastewater treatment plants (WWTPs) have rarely been reported. Based on the targeted analysis and suspected screening, this study investigated the distribution of psychotropic drugs and their transformation products (TPs) within the entire treatment processes in WWTPs and their receiving rivers. The results indicated that 13 out of 47 psychotropic drugs are widely observed across wastewater, sludge, receiving river water, and sediment, respectively. The aqueous removal efficiencies of most psychotropic drugs exhibited their significant recalcitrance in wastewater treatment processes. For instance, venlafaxine (VEL) was slightly removed by 2.64 % and 10.8 % in these two WWTPs. The concentrations of oxazepam (OZP) and lamotrigine (LMT) dramatically increased after the overall treatment processes due to their metabolic conversion and regeneration processes, respectively. Given the recalcitrance of psychotropic drugs, the identified TPs generated within WWTPs were not abundant, but a wider variety of TPs were identified from human metabolites. A total of 25 TPs were identified via the suspect screening analysis, of which nine were newly identified. In receiving rivers, the risk quotient (RQ) presented OZP, sertraline (SER), and VEL posed high potential risks; the integration of the toxicological priority index (ToxPi) and the toxicity-weighted concentration (TWC) suggested TP-CIT-322 and TP-OCX-195 as the high-priority contaminants. Given the recalcitrance and environmental risks of psychotropic drugs and their TPs in WWTPs and environments, it is crucial for the further exploration of their effective treatment technologies and emission control strategies .
