Summary: Gas chromatography-mass spectrometry (GC-MS) is widely used in environmental analysis and derivatization can broaden its analyte range. Silyl derivatives, such as N-methyl-N-(trimethylsilyl) trifluoroacetamide (MSTFA) and N, O-bis(trimethylsilyl)trifluoroacetamide (BSTFA), improve the volatility and stability of compounds, making them suitable for detection, structural elucidation, and quantification. This study optimized the derivatization conditions for 70 selected contaminants of emerging concern (CEC) and found that the BSTFA + 1% trimethylchlorosilane (TMCS) gave the best yield. The stability of the CEC-trimethylsilyl (TMS) derivatives was examined under various conditions, and it was recommended to store the derivatized samples at -18 degrees Celsius for up to 20 weeks with no more than two freeze-thaw cycles.

Summary: Ibuprofen, as an emerging contaminant, is present in various environments at concentrations that adversely affect aquatic organisms. It poses a significant environmental problem due to its high consumption rate and low degradation rate. The lack of effective strategies for its removal and the limited studies on its ecological impact on a global scale make it a neglected contamination problem. This review focuses on updating information on ibuprofen as an emerging environmental contaminant and its potential biodegradation using bacteria as an alternative technology.

Summary: Cardiovascular diseases (CVD) are the leading cause of death worldwide, and the vascular endothelium may play a role in their pathophysiology. Octylmethoxycinnamate (OMC), a commonly used UV-B filter, has been found to act as an endocrine disruptor. This study aimed to investigate the direct effects of OMC on human umbilical arteries (HUAs) with endothelium and the underlying mechanisms. The results showed that OMC had a rapid and endothelium-dependent arterial relaxant effect on HUAs contracted with serotonin and histamine. However, this effect was inhibited in HUAs contracted with potassium chloride and appeared to be dependent on the presence of endothelium. Computational modeling studies also revealed the binding of OMC to several proteins involved in vascular function. Overall, the vascular effect of OMC may involve activation of different pathways, including the NO pathway, COX pathway, or endothelin-1 pathway.

Summary: This work provides a critical review of recent studies on the use of heat-activated persulfate to degrade persistent micropollutants. The influence of various operating parameters, such as temperature and oxidant concentrations, is discussed, with higher temperatures and oxidant concentrations generally improving efficiency. The effect of the aqueous matrix is particularly emphasized, as studies have shown that the removal of pollutants decreases with increased complexity of the aqueous matrix, unless specific oxidative species are produced. The study also highlights the growing interest in combining different processes for persulfate activation and summarizes recent research on hybrid systems for micropollutant destruction.

Summary: Pyrolysis of lemon stalks at 850 degrees C under limited oxygen produces highly active and selective biochar that can activate persulfate ion and oxidize sulfamethoxazole (SMX). The biochar consists mainly of carbon and oxygen atoms, with calcium and potassium as the most abundant minerals. It has a moderate specific surface area of 154 m(2) g(-1) and contains carbonate species, possibly in the form of calcium carbonate. In ultrapure water, complete degradation of 0.5 mg L-1 SMX can be achieved within 20 minutes using 500 mg L-1 sodium persulfate (SPS) and 100 mg L-1 biochar. The biochar remains stable for at least five cycles and shows potential as a sustainable, metal-free catalyst.

Summary: The pursuit of low-cost, high-efficiency co-catalysts without noble metals in photocatalysis has attracted significant interest in recent years. In this study, a series of cobalt phosphide (CoP 0.125-1.00 wt.%) promoted bismuth vanadate (BiVO4) photocatalysts were synthesized and characterized. The efficiency of these photocatalysts was investigated for sulfamethoxazole (SMX) degradation under simulated solar light irradiation. The results showed that the deposition of a small amount of CoP on BiVO4 enhanced SMX degradation.

Summary: This study examines the use of pristine Mo2C as a sodium persulfate (SPS) activator for the degradation of the drug losartan (LOS). The results show that acidic pH enhances LOS decomposition, and the apparent kinetic constant decreases with higher LOS concentrations. Sulfate radicals, hydroxyl radicals, and singlet oxygen are identified as the reactive species in LOS oxidation, with singlet oxygen being the predominant species. The addition of chloride accelerates the degradation rate, while bicarbonate and organic matter reduce the efficiency. The study also investigates the application of the Mo2C/SPS system for simultaneous LOS decomposition and elimination of Escherichia coli, with significant synergistic effects observed when simulated solar irradiation is present.
