Summary: A novel gold particles-modified three-dimensional reduced graphene oxide (3D-rGO/AuNPs) electrochemical aptasensor was reported for the simultaneous detection of isocarbophos and edifenphos. The use of different metal ions resulted in discrete differential pulse voltammetry (DPV) peaks, allowing the identification of different pesticides and their concentrations. The aptasensor could be reprogrammed for the detection of various toxins, antibiotics, and other small contaminants.

Summary: In this work, polyaniline (PANI) and overoxidized polyaniline (oPANI) nanorods doped by phytic acid (PA) were prepared as non-enzymatic malathion sensors. PA doping had a significant influence on the structural and morphological properties, conductivity, and detection performance of the electrode materials. PA-PANI exhibited high affinity towards malathion, hindering the redox reaction of PANI molecules, while PA-oPANI showed good catalytic performance, enhancing the electron transfer process. Both enzyme-free electrochemical sensors exhibited excellent stability, anti-interference ability, recovery in real samples, and wide linear ranges with low detection limits, indicating their potential as malathion sensors. Further exploration is needed for the reproducibility of the PA-oPANI sensor through anodic polarity processing.

Summary: This study constructed a new SERS substrate Fe3O4@UiO-66(Zr)@Ag nanoparticles (FUAs) with excellent SERS detection sensitivity, uniformity, reproducibility, and stability. It exhibited a high Raman enhancement factor (5.62 x 106), low limit of detection (LOD, 2.11 x 10-11 M), and RSD (12.41%) for 4-NBT, while maintaining 81% SERS activity within 60 days. FUAs took advantage of the strong affinity of UiO-66(Zr) for organophosphorus pesticides (OPs) to achieve trace OPs detection, showing potential for detecting OPs in foods.

Summary: The abuse of organophosphorus pesticides in tea planting poses potential health risks to consumers. Reliable techniques are needed to remove these pesticides from tea infusion. This study investigated the modification of carbonized bacterial cellulose (CBC) to improve its adsorption performance. The N-CBC treated with hydrazine hydrate showed the best adsorption effect, with a removal rate 13 times higher than CBC. The study also elucidated the adsorption mechanism and suitable models to describe the process, and confirmed no significant changes in tea infusion quality after N-CBC treatment.

Summary: NO2 emissions from wall-mounted gas stoves used for household heating have become a significant source of indoor pollution in Chinese urban areas. The high indoor concentration of NO2 poses potential health risks to residents. It is urgently necessary to establish relevant regulations and implement emission reduction technologies to reduce NO2 emissions from wall-mounted gas stoves.

Summary: This study investigates the relationship between dissolved organic matter (DOM) and Rare Earth Elements (REEs) in sediments from Yundang Lagoon, China. The results show four distinct fluorescent components, with protein-like substances being the most prevalent. Additionally, the total fluorescence intensity and LREE concentrations exhibit a synchronized increase from Outer to Inner to Songbai Lake core sediments. The findings demonstrate a strong correlation between DOM content and pollution levels.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: The choice of workflow in wastewater surveillance has a significant impact on SARS-CoV-2 concentrations, while having minimal effects on HF183 and no effect on HAdV 40/41 concentrations. Certain components in the workflow can be interchangeable, but factors such as buffer type, chloroform, and homogenization speed can affect the recovery of viruses and bacteria.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Summary: In this study, inverse vulcanized polysulfides (IVP) were synthesized by reacting molten sulfur with 4-vinyl benzyl chloride, and then functionalized using N-methyl D-glucamine (NMDG). The functionalized IVP showed a high mercury adsorption capacity and a machine learning model was developed to predict the amount of mercury removed. Furthermore, the functionalized IVP can be regenerated and reused, providing a sustainable and cost-effective adsorbent.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
