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: In this study, the optimal coagulation conditions using FeCl3 and AlCl3 coagulants and PAM flocculants to reduce silica and TEP concentration in RO technology were explored. The best removal effect on pollutants was observed at pH 7 with a dosage of 50 mg/L for both coagulants. Additionally, the study determined that the best PAM dosages for FeCl3 and AlCl3 were 5 mg/L and 1 mg/L, respectively, considering the removal rate of pollutants and the residual amount of coagulation metal ions. The removal mechanisms of pollutants by coagulation pretreatment were determined to be adsorption, electric neutralization, and co-precipitation.

Summary: In recent years, it has become increasingly evident that microplastic pollutants heavily contaminate water sources, posing a potential threat to humans and wildlife. Photocatalytic degradation of these pollutants has emerged as a powerful technique, but limited research has been conducted in this area.

Summary: This study investigates the co-culture mechanism of Rhodococcus ruber HJM-8 and Paracoccus communis YBH-X during N,N-dimethylacetamide (DMAC) degradation. The efficient cooperation between the two strains via parallel and cascaded degradation leads to a higher removal efficiency of total nitrogen (TN) in co-culture compared to monoculture. The study also identifies intercellular nanotubes as a unique contact-dependent interaction, which improves material transfer and enhances cell connection in co-culture. The differentially expressed genes in the co-culture have associations with cell metabolism, nanotube generation, and genetic material transfer. The co-culture system is validated for wastewater treatment, showing potential for application.

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 analyzes the environmental footprint patterns of the plastics value chain in the European Union and finds that most countries belong to a cluster with relatively low global warming potential. However, despite an increase in plastic waste recovery rate, the environmental impact has not been reduced, and the global warming potential tends to increase with higher plastic waste amounts.

Summary: The considerable amount of produced water discharged by the oil industry can cause environmental imbalance due to its harmful components. This study investigated the adsorption capacity of Zinc Imidazolate Framework-8 (ZIF-8) for crude oil removal from synthetic produced water. ZIF-8 exhibited high crystallinity and thermal stability, and its adsorption process was found to be spontaneous and exothermic.

Summary: This study examines the short-term effects of exposure to nitrogen dioxide, ozone, and oxidative potential on mortality rates in Jiangsu, China from 2014 to 2020. The findings show a significant increase in all-cause, cardiovascular, and respiratory mortality associated with these pollutants. Women and individuals over 75 years old are particularly susceptible, especially during warm seasons.

Summary: This study analyzed the terpenoid composition in different chemotypes of Cinnamomum camphora and evaluated their effects on the cyanobacteria Microcystis aeruginosa. Eucalyptol and borneol chemotypes showed stronger algaecidal effects, with eucalyptol and borneol being the main components. The mechanism of action involved the increase of reactive oxygen species levels and caspase-3-like activity, leading to apoptosis-like programmed cell death. These findings suggest that eucalyptol and borneol chemotype extracts and their typical monoterpenoids have potential as algaecides for controlling cyanobacteria.

Summary: This study conducted a bibliometric analysis to comprehensively explore the research hotspots and trends of zero-valent iron (ZVI)-based materials in environmental remediation. The results showed that China is the major contributor in terms of publications, while the USA has the highest academic influence. The primary research topics include reductive dechlorination, sulfate radical, and arsenic removal. However, the environmental impact and toxicity of ZVI-based materials have not received sufficient attention.

Summary: This article summarizes the importance and advantages of anaerobic digestion (AD) processes in the treatment of industrial organic wastewater, and introduces some advanced AD processes. AD processes are optimized through enhancement strategies to improve wastewater treatment and energy recovery. The combination of anaerobic ammonia oxidation (Anammox) with AD processes is introduced as a feasible solution for carbon-neutral wastewater treatment. In addition, the integration of AD processes with other bio-processes is proposed for low-carbon treatment in the future.
