Summary: This paper compares the separation performance and energy consumption of pressure swing adsorption and amine-absorption processes in upgrading biogas. The results show that the amine-absorption technology has better purity and recovery of products. However, the pressure swing adsorption process has lower energy consumption but lower biomethane purity and methane recovery.

Summary: This study investigated the performance of three different treatment technologies in a wastewater treatment plant in El-Gouna, Egypt. The COD removal efficiencies of the three systems were comparable, but EAAS had a slightly lower NH4 removal efficiency compared to HFBBR and HMBBR. BioWin software was used to simulate and analyze the systems, and recommended the most suitable configuration for upgrading the existing system.

Summary: This study investigated the use of three microalgae-fungi/bacteria symbiotic systems stimulated with the strigolactone analog (GR24) to simultaneously remove nutrients from treated piggery wastewater and CO2 from biogas. The Chlorella vulgar-is-Ganoderma lucidum-endophytic bacteria co-cultivation systems achieved the best photosynthetic performance and microalgae growth at an initial COD concentration of 1200 mg/L. The highest nutrient/CO2 removal efficiencies were obtained under the appropriate COD concentration (1200 mg/L), and 10-9 M GR24 significantly accelerated the removal efficiencies.

Summary: Algae-based wastewater treatment technologies have great potential for economic and environmental benefits, but have not yet been successfully applied in municipal wastewater treatment plants for nitrogen and phosphorus removal. This paper reviews the literature and analyzes the reliability and readiness level of five types of reactors. The study shows that reactors with higher control over technological parameters are more reliable, but algae harvesting and additional costs are barriers to their deployment.

Summary: Recent studies have shown that electron beam technology can completely break down PFOA and partially break down PFOS under certain conditions, such as high pH, nitrate content, alkalinity, and anoxic conditions. Lab experiments demonstrated significant reductions in concentrations of both PFOA and PFOS in water and sand when exposed to eBeam technology at a dose of 50 kilograys (kGy).

Summary: The COVID-19 pandemic has emphasized the importance of wastewater surveillance alongside clinical data. Various online information dashboards have been developed independently to present SARS-CoV-2 wastewater data to public health officials and the general public. A review of 127 dashboards from 27 countries shows high variability in terms of data presentation formats, labeling methods, and regional differences. The lack of uniformity across dashboards hinders the optimal use of wastewater surveillance data on a global scale and may lead to miscommunication of public health risks. It is crucial to establish standardized conventions and best practices for data presentation in order to improve scientific communication in this field.

Summary: Due to its simple process, environmental friendliness, and low operating costs, biometallurgy has become a popular technology for metals recovering from low-grade ores and tailings. An optimized agar was used to isolate and grow functional bacteria, resulting in the successful isolation of six functional stains. These strains were further tested for their ability to leach metals from polymetallic sulfide tailings, with significant improvements observed when the strains were mixed together. The selection of leaching process should be based on tailings composition and target metals.

Summary: An Endocrine Disrupting Chemical (EDC) is a compound that disrupts the function of the endocrine system and is found in the environment. EDCs, such as Bisphenol A and pesticides, have been shown to have negative effects on the female reproductive system. Understanding the relationship between EDCs and women's health is crucial for developing strategies to protect reproductive health and informing public policy decisions.

Summary: This study examines the association between urban Green and blue spaces (GBS) exposure and Emotion and behavior problems (EBP) in youth populations. The findings suggest that higher exposure to GBS, particularly green spaces (GS) and blue spaces (BS), is associated with a decrease in the risk of developing total difficulties in young individuals. The joint effect of GS and BS may also contribute to the decrease in EBPs.

Summary: Air pollution is associated with a range of health issues and gestational exposure to environmental pollutants may be linked to neurodevelopmental disorders. This study investigated the effects of oral gestational exposure to particulate matter (PM) on ultrasonic vocalizations (USV). The findings suggest that this exposure may lead to social deficits and abnormal gene expression related to neurotransmitter systems. Further research is needed to better understand the effects of air pollution on neurodevelopmental disorders and the neurotransmission systems involved.

Summary: The present study investigated the sustainable approach for wastewater treatment using waste algal blooms. The biochar produced by the marine algae Ulva reticulata was used to remove chromium, nickel, and zinc from aqueous solutions. The study examined the adsorbents' properties and stability using SEM/EDX, FTIR, and XRD. The results showed that the biochar had high removal efficiency for the toxic metals, and the packed bed column effectively removed the heavy metal ions. The Thomas and Adams-Bohart models were found to best fit the regression values, and desorption studies were conducted to understand the sorption and elution processes.

Summary: The selection of predictor variables is crucial in building a digital mapping model for potentially toxic elements (PTEs) in soil. Traditionally, spatial and spectral parameters have been used as predictor variables, but the temporal dimension is often overlooked. This study demonstrates the value of incorporating temporal indices in the model, leading to significant performance improvements. The temporal-spatial-spectral covariate combinations used in a random forest (RF) algorithm achieve satisfactory mapping accuracy and outperform other methods.

Summary: Heteroatom doping can reconfigure the electronic structure of heterogeneous catalysts, leading to the development of advanced oxidation water purification materials with superior performance and stability. In this study, a series of catalysts with different elemental doping were prepared using a simple and environmentally friendly method. The S-doped NiCo2O4 catalyst showed excellent catalytic performance for the removal of Tetracycline, with significantly increased kinetic constant and high oxidation and mineralization efficiency in a wide pH range. The degradation process was dominated by non-radical oxidation pathway after S doping, and the overall process moved towards low toxicity.

Summary: This study investigated the bacterial degradation of naphthalene (NPT) isolated from crude oil-contaminated soil. Bacillus sp. GN 3.4, a potential bacteria for NPT biodegradation, was isolated and the optimal conditions for NPT degradation were determined. The study suggests that Bacillus sp. GN 3.4 could potentially aid in bioremediation by eliminating NPT from the soil.
