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 production and use of chemicals are increasing worldwide, leading to an increasing number of potentially harmful chemicals entering the environment. Recent advances in analytical techniques have provided new opportunities for detecting a wide range of contaminants in water that cannot be detected by traditional targeted analysis methods. This review summarizes the advances in suspect screening analysis (SSA) and non-target analysis (NTA) of polar emerging contaminants (ECs) in various matrices over the past five years, including sampling and extraction approaches, GC or LC-HRMS analysis, data processing, evaluation, and reporting. The challenges and future trends in SSA and NTA monitoring of polar ECs are also discussed.

Summary: The increased demand for plant production products is a significant concern due to the current focus on high agricultural yields in citrus production. This study aimed to analyze pesticide residues in satsuma mandarins, including highly polar compounds. Samples were collected over three consecutive years in Turkey, and the residues were analyzed using QuEChERS extraction and LC-MS/MS and GC-MS/MS determination methods. The results showed the presence of various residues, including two highly polar substances, with some samples exceeding the maximum residue levels (MRL). Phosphonic acid and spirotetramat were the most frequently found pesticides, and their concentrations varied in the mandarin samples. These findings are important for assessing pesticide presence, identifying potential risks, and ensuring consumer safety.

Summary: This study presents a novel approach for the rapid and sensitive detection of organophosphorus nerve agents (OPNAs). The method involves the use of functionalized silver nanoparticles immobilized with acetylcholinesterase and 5,5'-dithiobis-(2-nitrobenzoic acid) as a detection substrate. The introduction of enzyme activity indicator significantly improves the detection sensitivity, and different OPNAs exhibit different SERS intensities due to their inhibition capacities of acetylcholinesterase. This new strategy has great potential in public security early warning and environmental analysis.

Summary: The study revealed that the double constrained correspondence analysis (dc-CA) and CWM-RDA analysis methods can identify the relationships between benthic macroinvertebrate communities and environmental factors, with dc-CA being more effective than CWM-RDA. Traits such as aquatic stages, reproduction techniques, dispersal tactics, locomotion, and substrate relations were found to be associated with pollutants and water quality measurements. The dc-CA analysis showed that the set of environmental variables was more effective in explaining the community data than the trait set.

Summary: This study highlights that temperature is the main driver for changes in zooplankton communities, followed by salinity and chlorpyrifos. The three stressors contributed to a decrease in zooplankton diversity, with an increase in zooplankton abundance driven by higher temperatures. Salinity affected Cladocera and resulted in Copepoda increase at lower temperature, while reducing the abundance of all major zooplankton groups at higher temperature. Chlorpyrifos primarily affected Cladocera, with antagonistic effects on sensitive taxa in combination with salinity at both temperature scenarios.

Summary: The rapid urbanization in the Brazilian Amazon has led to untreated wastewater containing pharmaceuticals and other chemicals being discharged into freshwater ecosystems, posing potential risks to biodiversity. Urban areas are identified as hotspots for chemical contamination, with mixtures containing numerous compounds and some reaching global maxima in exposure concentrations. Chemical pollution may have long-term effects on 50-80% of aquatic species near urban areas.

Summary: The recovery time of ecological communities after disturbances differs, with multivariate composition taking longer to recover. This study used network analysis to find that changes in interaction strength are closely related to compositional changes, and rewiring of postdisturbance interaction strength is the main cause of observed compositional changes. Pesticide interactions are significant in the long term only when both interaction strength and food-web architecture are reshaped by disturbances.

Summary: Developing population models for assessing risks to threatened or endangered plant species is challenging due to limited data on their life histories. This study developed a novel approach to identify data-rich nonlisted species as representatives for species listed under the ESA in population model development. The results showed that listed species are widely distributed across the plant phylogeny and do not share common vulnerability characteristics. Lifespan and age at maturity are important factors for distinguishing species clusters.

Summary: This study compared the uptake and bioconcentration of two hydrophobic organic chemicals in fish exposed to the chemicals through water alone or in combination with contaminated polyethylene microplastics (MPs). The presence of contaminated MPs did not enhance but rather decreased the bioconcentration of the chemicals in fish. Enzyme activity levels in fish were only significantly altered in the presence of MPs for alkaline phosphatase.

Summary: Untangling the relationship between network complexity and ecological stability under climate change, particularly extreme climatic events, is a challenging task. This study explores the effects of extreme heatwaves on the complexity of freshwater ecosystems and its correlation with stability components of the community. The findings suggest that reduction in network complexity leads to decreased functional and compositional resistance, while increased link-weighted network complexity improves functional and energy flux recovery and resilience but increases compositional instability.

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.

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.
