Summary: This review discusses how aqueous two-phase systems (ATPS) can efficiently extract, pre-concentrate, and clean-up analytes in aqueous samples to determine compounds classified as emerging contaminants (ECs). ATPS is an alternative to conventional liquid-liquid extraction techniques, predominantly composed of water and based on the principles of green chemistry. This simple and low environmental impact technique has been successfully employed for the analysis of different classes of emerging contaminants.

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: This study provides a detailed analysis of the different contributions of microplastics (MPs) to a freshwater system in South America, with urban sewage discharge identified as the main source of pollution. The study found that 97% of the total MPs in the system came from effluent from wastewater treatment plants. The study also revealed that microfibers, primarily polyethylene fibers, accounted for a significant portion of the MPs.

Summary: There has been a growing concern in the past decade about the presence of cytostatics in natural waterbodies. Conventional wastewater treatments have been found to be ineffective in removing them, thus new processes are being explored. This study investigates the performance of different ozonation and peroxone processes in degrading cytostatics, and the results show that these processes are effective in removing them.

Summary: This study investigates the adsorption capacity of two activated carbons on five model contaminants in different aqueous matrices. The results show that the AC1 has a higher adsorption capacity in the downflow mode, but preferential pathways reduce its useful lifetime. Additionally, the wastewater treatment effluent and pretreated water have a significant impact on the adsorption capacity of the contaminants.

Summary: This study investigates the presence of 20 emerging contaminants (ECs) in wastewater treatment plants (WWTPs) in north India, and found that all 20 ECs were identified in the influent and effluent, and 13 were identified in the final sludge. The removal of ECs in the WWTPs was mainly attributed to biodegradation/biotransformation. The risk assessment showed potential risks to algae, daphnia, and fish from certain ECs.

Summary: This study successfully removed five cytostatics of concern from Portuguese WWTP effluents using non-catalytic ozonation. CAP and MPA were quickly eliminated while BICA, CYC, and IFO required breakdown via hydroxyl radicals generation for degradation. Increasing ozone dosage improved removal efficiency, with CAP, MPA, and IFO completely eliminated after 180 minutes.

Summary: This study focused on evaluating the potential use of corn stalks as an adsorbent for removing organophosphate dimethoate pesticides from aqueous solutions. Experimental results showed that removal of dimethoate was more effective in alkaline conditions. Several models were applied to analyze the equilibrium isotherms, with the Sips, Redlich-Peterson, and Toth models providing the best fit for the experimental data and accurately describing the adsorption process of dimethoate on corn stalks.

Summary: The objective of this research is to determine the effectiveness of the electromagnetic equipment TK3K in preventing incrustations in pipes. The study uses a method of forced precipitation of calcium carbonate to analyze the differences in turbidity, absorbance, and particle size between treated and untreated water. The results show that the treated water has lower parameter values and that longer treatment time does not produce different results, while an increase in temperature leads to a greater decrease. This method provides a simple and fast way to verify the effect of electromagnetic treatment.

Summary: Biomass layered hybrids were synthesized by in situ growth from rice husk and microwave-assisted synthesized MIL-53(Al) particles, leading to reduced reaction times. The resulting hybrid (MIL-53(Al)@RH) showed high crystallinity, thermal decomposition phases, and functional groups. The hybrid particles exhibited easy separation during heterogeneous processing and maintained the properties of MIL-53(Al) for the removal of Oxytetracycline, Diclofenac, and Glyphosate in aqueous solutions.

Summary: The aim of this study was to investigate the potential of the hybrid material MIL-53(Al)@RH for the adsorption of glyphosate in aqueous solution. The results showed that a maximum adsorption capacity of 296.95 mg g(-1) was achieved in 30 min with a ratio of 0.04 g MIL-53(Al)@RH/50 mL of solution at pH(0) 4. The adsorption kinetics and equilibrium were appropriately described by Avrami and pseudo-second order models, and Langmuir and Sips models respectively. Hydrogen bonds, pi*-pi interactions, and complexation between the metal centers of MIL-53(Al) and the anionic groups of glyphosate were postulated as the adsorption mechanisms.

Summary: Per- and polyfluoroalkyl substances (PFASs), widely used since 1940 for their stability, have raised global concern due to their presence in water and soil, posing threats to the environment and human health. This work reviews the literature on remediation techniques for PFASs-contaminated soil and water. Ball milling, chemical oxidation, and thermal desorption are effective techniques for soil remediation, while electrocoagulation, membrane filtration, and various types of treatments show promising results for water remediation. The improvisation and application of these techniques on a larger scale are necessary to confirm their efficiency.

Summary: The objective of this research was to evaluate the performance of a continuous electro-coagulation (EC) reactor for treating surface waters with high turbidity levels. The study found that increasing the flow rate, voltage, and operating time improved turbidity removal, but high initial turbidity levels had a negative impact on removal. The continuous EC test achieved a high turbidity removal efficiency, but resulted in an increase in aluminum concentration, exceeding the limits set by WHO. Economic analysis demonstrated the feasibility of implementing the continuous EC reactor on a larger scale.

Summary: The aim of this study was to extract and characterize silica materials from various agro-industrial wastes including sugarcane bagasse, corn stalk, and rice husk. The results showed that silica yields of 17.91%, 9.39%, and 3.25% were obtained for RH, CS, and SCB, respectively. The textural properties indicated that the siliceous materials had mesoporous structures, with SCB and CS forming crystalline SiO2 and RH forming amorphous. XPS spectra demonstrated the presence of Si4+ species in RH, and Si3+/Si4+ tetrahedra in SCB and CS.

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.
