Summary: The increasing trend of industrialization leads to the release of industrial effluents. Waste water treatment is important for waste disposal and sustainability. Sustainable and energy efficient treatment methods are attractive, but existing technologies have sustainability issues. Conventional and advanced technologies are implemented for wide range of effluents, but secondary sludge generation is unaddressed. Biochar is effective for certain contaminants. Nanotechnology and membrane technology are promising for waste water treatment. Carbon nano structures, nano filters, graphene, and nano magnets are potential candidates.

Summary: Wastewater treatment plants (WWTPs) play a crucial role in removing microplastics (MPs) from urban wastewater. However, there is currently a lack of reliable and efficient methods for extracting MPs, especially in organic-rich matrices such as sludge samples. In this study, a two-step digestion process was developed and optimized, allowing for over 90% extraction efficiency of MPs from sludge samples. The recommended dosage of digestion reagents was found to be 100 ml 30% H2O2 + 100 ml 1 M HNO3 for samples with mixed liquid volatile suspended solids (MLVSS) levels lower than approximately 0.43 g. This study also examined the characteristics of MPs in two WWTPs in Shenzhen, revealing high concentrations of MPs in influent, effluent, and dewatered sludge, with rayon and polyester being the dominant polymers.

Summary: The fungal symbiosis with plant root system is recognized as a way to enhance plant growth and defense against various stress conditions. The excessive use of chemical fertilizers has led to soil contamination. Using microbial consortium such as plant growth promoting fungi (PGPFs) is gaining importance worldwide. PGPFs exhibit multiple activities through promoting plant growth, inducing resistance, combating diseases, and detoxifying toxic chemicals. The key to these properties is the secretion of biomolecules by the fungi. This review focuses on the role of PGPFs in inducing systemic resistance and detoxifying heavy metals. Understanding the mechanism of PGPFs can contribute to developing sustainable agriculture by alleviating heavy metal stress in plants and soil.

Summary: In this study, Mg-S co-doped TiO2 nanoparticles were synthesized using the sol-gel method and their photocatalytic activity under simulated visible light was examined. The Mg-S co-doped TiO2 nanoparticles exhibited a pure anatase structure with a decreased band gap energy compared to pristine TiO2. They showed excellent photocatalytic activity and achieved a maximum degradation efficiency of 94.8% for methylene blue dye. Additionally, the antimicrobial activity of Mg-S co-doped TiO2 nanoparticles against Escherichia coli and Staphylococcus aureus was investigated, and the maximum antibacterial activity was achieved by doping and co-doping with Mg/S.

Summary: The accumulation of plastics poses a worldwide environmental risk. Polyethylene terephthalate (PET) degrades slowly and produces hazardous substances, highlighting the need to eliminate plastic waste from the environment. This study focuses on the potential of naturally occurring microbial strains isolated from plastic waste dumping sites to degrade PET. The results show that a microbial consortium (S. aurantiaca + B. subtilis + A. flavus + A. niger) can effectively degrade PET, indicating its potential to eliminate PET in plastic contaminated sites without health or environmental risks.

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.
