Summary: Contaminants of emerging concern can have potential adverse effects on humans and aquatic life, making it important to consider their impact in water management decisions. This research examines the effects of water reuse practices on the concentrations of various contaminants in the Los Angeles River. The results show that water reuse generally improves water quality, except for one specific contaminant, but the improvements may not be sufficient to mitigate high concentrations downstream of effluent discharge points.

Summary: The prevalence and impact of contaminants of emerging concern (CECs) have raised growing concerns. However, the environmental monitoring of CECs has been limited in low- and middle-income countries due to the lack of advanced analytical instrumentation locally. In this study, a nontargeted and suspect screening approach using liquid chromatography coupled with high-resolution mass spectrometry was employed to identify known and unknown pollutants in wastewater and groundwater samples from the Glen Valley wastewater treatment plant in Botswana. The results revealed the presence of various pharmaceuticals, illicit drugs, and other compounds, emphasizing the importance of wastewater treatment plants as a major pathway of chemical pollution.

Summary: High-rate algal ponds (HRAP) are an alternative method for wastewater treatment that can contribute to the circular economy by valorising reclaimed water and algal biomass. Studies show that HRAPs have good removal efficiency for nutrients and contaminants, but further research is needed to understand the risks and requirements of safe wastewater and biomass reuse.

Summary: This article presents the results of a study on the potential contamination of emerging concern contaminants (CECs) and pesticides in Tunisian groundwater. The study found a significant presence of CECs and pesticides in Tunisian groundwater, with concentrations comparable to those found in industrialized countries. Wastewater treatment plants were identified as the main source of pollution, with substances such as caffeine, salicylic acid, and ibuprofen being ubiquitous. Triazines herbicides and carbamates insecticides posed the highest concern among the pesticides due to their widespread presence, high leachability potential, and high toxicity.

Summary: Wastewater treatment plants are major sources of Emerging Chemicals of Concern (CECs) in aquatic environments, impacting aquatic ecosystems. This study investigated 164 CECs at 15 locations, with CEC concentrations varying widely between WWTPs. The K-d of CECs correlated with K-ow, allowing for prediction of their distribution in water and solids. WWTP effluent had higher CEC concentrations than upstream waters, potentially impacting downstream ecosystems.

Summary: The aim of this study was to develop a new, highly compact multi-option photo reactor for the removal of emerging contaminants from wastewater. Different advanced oxidation processes, including electrochemical oxidation, photolysis, and photocatalysis with TiO2 nanotubes array, were investigated and combined to create a photoelectrocatalytic oxidation process. The efficiency of these processes was evaluated by measuring the removal of ofloxacin, a pharmaceutical compound used as a model contaminant. SEM and XRD characterization confirmed the formation of anatase-phase nanotubes with suitable dimensions for photocatalytic reactions. The results demonstrated that the coupling of these technologies was effective, leading to high process efficiencies.

Summary: This study conducted a territorial-scale ERA on CECs detected in the effluents of 10 WWTPs in a highly urbanized territory using LC-QToF-MS, focusing on pharmaceutical residue and pesticides. The results identified high risks for several CECs individually, with additional significant risks found in mixtures of CECs. The study highlighted the importance of assessing not only individual CECs but also their combined effects on ecotoxicological risks in urban streams.

Summary: This study investigates the presence of contaminants of emerging concern (CECs) in the Volta River, Ghana, and examines their effects on microbial communities. The results show the presence of antibiotics and per- and polyfluoroalkyl substances (PFAS) in both water and sediment samples, although at relatively low concentrations. The diversity of microbial genes increased in sites associated with urban development, sand mining, agriculture, and shellfish processing, and the spike in antibiotic-resistant genes (ARGs) in sediment samples was related to agriculture. The findings suggest that the Volta River is affected by CEC contamination, but the overall concentrations are low.

Summary: The study found that S. leopoliensis is more sensitive to BPA and BPF, with both showing comparable toxic potential and similar hazard to phytoplankton. In different concentration ranges, additive effect was observed in P. subcapitata with BPA, while no pronounced combined effect was seen in S. leopoliensis. Comparison suggests that in certain industrial areas, BPA may pose an environmental risk, while BPF does not.

Summary: Macrolide antibiotics have been recently added to the EU Watch List of contaminants in the aquatic environment, but a comprehensive assessment of these antibiotics in different environmental compartments is still lacking. In this study, a new method was developed to determine an extended range of macrolide residues in sediment and soil samples, showing that these residues tend to persist in the aquatic environment.

Summary: The study found that BPF and BPS degrade readily during biological wastewater treatment, with BPF degrading faster than BPS. The absence of any additional organic carbon source significantly slowed down the degradation rate, particularly for BPS. Machine learning algorithm identified new biotransformation products for both BPF and BPS, supporting possible new biodegradation pathways.

Summary: This study investigated the impact of adding a membrane filter between a glass fibre filter and the solid phase extraction (SPE) cartridge on the GC/MS analysis of 48 emerging organic micropollutants in wastewater. The results showed varying effects of the additional filtration step on the analysis, with positive, negative, and no effects observed depending on the concentration and nature of the analytes. Compounds with stronger interactions with colloidal OC were found to have higher hydrogen bond donor ability and larger molar volume.

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: 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: 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.
