Summary: With the increasing seriousness of environmental pollution, more attention is being paid to environmental analysis. Chemiluminescence (CL) has emerged as a powerful technique for pollution analysis due to its low interference, excellent sensitivity, rapidness, and simplicity. Nanomaterials such as MOFs, BPQDs, CDs, MoS2, LDHs, and noble metal NPs have been utilized to enhance CL radiation in environmental analysis, thanks to their wide surface area, unique photoelectric properties, and excellent reactivity. This review summarizes the recent advances in nanomaterial-based CL for environmental pollutant analysis, focusing on inorganic ions, ROS, antibiotics, pesticides, and other harmful substances. Key challenges and future prospects in this exciting area are also highlighted.

Summary: City lockdown is effective in reducing new COVID-19 cases, and NO2 concentration is a useful indicator for evaluating the effectiveness of lockdown measures. Stricter lockdown measures lead to earlier decline in new cases and faster reduction in NO2 concentration. NO2 satellite observations are valuable for monitoring and managing non-pharmaceutical interventions during the epidemic.

Summary: The U.S. food system is primarily centralized, with only a few states producing the majority of fruits and vegetables. Reliance on long-distance transportation and supply chains makes the system vulnerable, as demonstrated during the COVID-19 pandemic. A decentralized and localized food system, facilitated by Food Hubs, offers a promising alternative. This study assesses the sustainability contributions of urban Food Hubs, finding that they reduce food transportation, lower waste, and improve access to fresh food, but may be weaker in water management and food security.

Summary: In this work, an electrophoretic approach based on micellar electrokinetic chromatography coupled with tandem mass spectrometry (MEKC-MS/MS) was proposed for the simultaneous determination of nine neonicotinoids (NNIs) and the fungicide boscalid in pollen and honeybee samples. The method achieved improved separation efficiency and sensitivity through a stacking strategy and a scaled-down QuEChERS sample treatment. The results demonstrated that the proposed method is an environmentally friendly, efficient, sensitive, and useful alternative for the analysis of NNIs and boscalid.

Summary: This study evaluates the potential of ion mobility spectrometry (IMS) to improve the analytical performance of liquid chromatography-mass spectrometry (LC-MS) workflows for the determination of ergot alkaloids (EAs) in cereal samples. Collision cross section (CCS) values are used for the unambiguous identification of EA epimers, and they have been validated and compared with predictions from machine-learning models. A LC-travelling wave ion mobility (TWIM)-MS method is developed for the analysis of EAs in barley and wheat samples, resulting in improved signal-to-noise ratio and ion chromatogram quality compared to the LC-TOF-MS method.

Summary: The consumption of blue-green algae (BGA) dietary supplements has increased due to their health benefits, but the production of cyanotoxins by cyanobacteria poses serious health risks. This study proposes the use of hydrophilic interaction liquid chromatography coupled with tandem mass spectrometry (HILIC-MS/MS) to detect cyanotoxins in BGA dietary supplements. The method successfully separated and quantified target toxins, including microcystin-leucine-arginine (MC-LR), microcystin-arginine-arginine (MC-RR), nodularin, anatoxin-a, and three non-protein amino acids. The analysis of different commercial supplements revealed the presence of DAB, AEG, and MCs in some samples, emphasizing the importance of monitoring these substances for safe consumption.

Summary: The increased consumption of blue-green algae (BGA)-based dietary supplements has raised concerns about food safety due to cyanotoxin presence. A study employed ultrahigh-performance liquid chromatography coupled to traveling wave ion mobility spectrometry/quadrupole time-of-flight mass spectrometry (UHPLC-TWIMS-QTOF) to establish a comprehensive database for phycotoxins. Cyanotoxins were confidently identified in commercial BGA dietary supplements based on retention time, m/z, and collision cross section values.
