Summary: This study investigated the occurrence of emerging contaminants in wastewater in the Northern Cape province of South Africa. The research found a wide variety of emerging contaminants in wastewater treatment plants, with most of them being recalcitrant to treatment processes. The presence of natural organic matter (NOM) was also observed in the wastewater samples. The study highlights the need for monitoring and quantifying emerging contaminants in wastewater treatment plants to mitigate their ecotoxicological risks.

Summary: The environmental impact of drugs of abuse in sediments has been understudied, with a new method developed in this study to analyze 20 drugs of abuse and metabolites in sediments from Spanish river basins. The most common compounds found were cocaine, methadone, and EDDP, with cannabinoids, THC, and methadone being the most abundant. The presence of EDDP, THC, and methadone in sediments at 28 locations poses a risk to sediment-dwelling organisms.

Summary: Glycosaminoglycans (GAGs) play a role in the treatment of many human diseases, especially in thrombosis, due to their anticoagulant activity. Novel electrophoresis-mass spectrometry methods have been developed to directly elucidate the structures of larger GAG chains with more biological importance, aiding in understanding the structure-activity relationship and quality control of GAG drugs.

Summary: The use of high-resolution mass spectrometry (HRMS) for pesticide residue analysis in food control has been studied over the last decade, showing challenges in efficacy compared to triple quadrupole mass spectrometers. Integrated modes like full scan, allions fragmentation, and target MS2 showed better results in targeted analysis, while optimization of spectral libraries can reduce false positive detects.

Summary: This study investigated the thermal dissolution process of soft coal and hard coal using different organic solvents. By employing off-line prep-HPLC, the soluble fractions were reliably separated and enriched, leading to the identification of heavy aromatic compounds not detected by GC/MS. The differences in composition between the two coals were elucidated, providing theoretical guidance for efficient coal utilization and mine safety.

Summary: Turmeric, widely used for different purposes, may contain mycotoxins and pesticides, which can contaminate the products and pose a health risk to consumers. Due to the complexity of turmeric and the variety of pollutants, special sample treatment is required. In this study, LC-HRMS analytical methods were used to analyze 195 pesticides and five mycotoxins in turmeric, achieving quantification limits below 4 μg/kg for mycotoxins and 10 μg/kg for pesticides, meeting regulatory requirements. The recovery values ranged from 70% to 120%, with relative standard deviations below 20%.

Summary: Pharmaceuticals released from wastewater treatment plants are emerging contaminants that can have biological effects at low concentrations. Conventional wastewater treatment methods are unable to completely remove these contaminants, leading to their presence in sewage sludge. This study developed a method to detect pharmaceuticals in sewage sludge and hydrochar using a combination of extraction and chromatography techniques. The method was successful in detecting various pharmaceutical compounds in the samples tested.

Summary: In this study, a specific, reliable, and suitable method for a fast and simultaneous analysis of 335 pesticides in ginseng was developed using liquid chromatography quadrupole mass spectrometry (LC-MS/MS) and gas chromatography quadrupole mass spectrometry (GC-MS/MS). The method was validated for linearity, sensitivity, selectivity, accuracy, and precision, with limits of detection (LOD) and limits of quantification (LOQ) ranging from 0.1-5.8 μg/kg and 0.3-17.5 μg/kg, respectively. Analysis of 467 ginseng samples from 2016 to 2019 revealed pesticide residues in 304 samples, but most were below the standard. The hazard quotient (HQ) of ginseng for detected pesticides was less than 1, indicating low risk.

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: Growing pressure from climate change and agricultural land use is destabilizing soil microbial community interactions. Little is known about microbial community resistance and adaptation to disturbances, hindering our understanding of recovery latency and implications for ecosystem functioning. This study found that anthropic disturbance and natural disturbance have different effects on the topology and stability of soil microbial networks.

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.
