Summary: This study successfully synthesized a conjugated microporous polymer (CMP) with high surface area, large conjugate system, and nitrogen-rich features at room temperature. The CMP was found to be a more efficient solid-phase extraction (SPE) column for nitro-musks compared to commercial columns. A sensitive and efficient method for determining five nitro-musks was established based on gas chromatography-mass spectrometry (GC-MS), showing excellent linearity, low limits of detection, and good repeatability. The method was successfully applied to detect trace nitro-musks in water and milk samples, and the mechanism was further discussed through simulation calculations.

Summary: In this study, a non-targeted LC-MS approach was used to identify 251 metabolites in Fruit of Rosa roxburghii Tratt (FRR). Differential compounds were identified to distinguish FRR from related species, and FRR exhibited higher biofunction potential. A quantitative LC-MS method was established to determine the contents of specific compounds, and it was found that FRR had higher contents compared to a related species. Furthermore, new ascorbic acid derivatives were discovered in FRR. These findings provide important information for the exploitation of FRR.

Summary: With the tightening restrictions on phthalate esters (PAEs), nonphthalate plasticizers (NPPs) are increasingly used. However, there is limited knowledge on the environmental occurrences, fate, and human exposure risks of many emerging NPPs. This study investigated the presence of NPPs and major PAEs in house dust, finding widespread occurrences of NPPs, such as ATBC, TCTM, TOTM, GMO, MO, and DiBA. Although current exposure may not pose significant health risks, potential hazards cannot be overlooked due to the lack of toxic threshold data and possible cocktail effects.

Thirteen polymethoxyflavones (PMFs), 28 carbohydrates, and 18 carboxylic acids were identified for the first time in C. aurantium. A total of 147 compositions were characterized, including 92 that were reported for the first time. Geographical features and principal discriminative compounds were determined, and the biofunctions of C. aurantium from different regions were speculated.

Summary: This study investigates the key characteristics of cardiovascular risk in diet-induced obese mice and corresponding normal mice exposed to DEHP at environmentally relevant concentrations. The results suggest that the cardiovascular system of obese individuals is more susceptible to DEHP exposure. DEHP exposure induces gut microbial remodeling and alters arachidonic acid metabolism, which is associated with adverse cardiovascular events. The findings provide new insights into DEHP-induced cardiovascular damage in obese individuals and suggest the potential use of arachidonic acid as a modulator of gut microbiota to prevent related diseases.

Summary: Trace amines (TAs) are metabolically related to catecholamine and associated with cancer and neurological disorders. A sensitive method using diisopropyl phosphite coupled with chip two-dimensional liquid chromatography tandem triple-quadrupole mass spectrometry (LC-QQQ/MS) was developed to simultaneously determine TAs and associated metabolites. The results showed significantly altered TAs and associated metabolites in hepatoma cells after sorafenib treatment, indicating the potential for elucidating disease mechanisms and diagnosing diseases based on the physiological functions of TAs.

Summary: This study used metabolomics and lipidomics combined with mass spectrometry imaging to reveal the mechanisms of enhanced growth of MCF-7 breast cancer cell spheroids exposed to triclosan (TCS). The results showed that TCS and TCS sulfate penetrated the entire area of the cell spheroids initially, but localized in the inner area later. Metabolomics data indicated that TCS exposure induced alterations in energy metabolism and the biosynthesis of glycerophospholipids and glycerolipids. Mass spectrometry imaging revealed enhanced energy supply in the peripheral area and increased energy storage in the inner area as potential contributors to the enhanced growth of MCF-7 breast cancer cell spheroids exposed to TCS.

Summary: Organophosphate flame retardants (OPFRs) were found in PM2.5 in Hong Kong, with chlorinated OPFRs being the dominant component. Plastic processing and waste disposal were identified as the main emission sources. Health risk assessment revealed a low-risk level for PM2.5-bound OPFRs, but relatively high noncarcinogenic and carcinogenic risks were associated with chlorinated OPFRs emitted from plastic processing and waste disposal.

Summary: We proposed an aroma correlation assisted volatilome coupled network analysis strategy to study Rosa roxburghii and discovered various aroma-active volatiles. The predominant aromas in R. roxburghii were found to be contributed by a series of homologous C6-and C8-acids, alcohols, aldehydes, esters, and terpenoids. Two aroma-active and aroma-contributing volatile groups, acid-aldehyde-alcohol-ester and terpenoid groups, were identified with the network analysis. Furthermore, the accumulation of C6-and C8-family homologous aliphatic volatiles was explained with linoleic and linolenic acid derived pathways. This strategy is practical for investigating the main aroma-active volatiles based on volatilome.

Summary: Tire wear particles (TWPs) are increasingly present in water, but little is known about their environmental consequences. In this study, TWP leachates were analyzed to identify potentially toxic organic substances using high-resolution mass spectrometry and toxicity identification. Thirteen substances were structurally identified, with cyclic amines found to be toxic to the tested algal species. Metabolomic analysis revealed differential metabolites associated with linoleic acid and purine metabolism, and oxidative stress was identified as a key factor in algal growth inhibition. This study highlights the risk posed by TWP leachable substances to aquatic organisms.

Summary: Existing and emerging persistent organic pollutants (POPs) pose significant threats to human health and economies. The development of effective mitigation strategies to remove or degrade these chemicals in the environment is crucial due to their persistence. Although various methods for electrocatalytic degradation of POPs have been developed in lab conditions, challenges such as harmful byproducts and limited working time hinder their practical application. This perspective work highlights high-entropy alloys as ideal catalyst materials for electrocatalytic degradation and discusses the use of AI to facilitate the design and testing of electrocatalysts. The challenges, negative effects, and solutions of applying AI in this process are also addressed.
