Cadmium (Cd) is a toxic heavy metal that has detrimental effects on agriculture crops and human health. Both natural and anthropogenic processes release Cd into the environment, elevating its contents in soils. Under Cd stress, strong plant-microbiome interactions are important in improving crop production, but a systematic review is still missing.

Emerging contaminants (ECs) pose great challenges to water treatment technology due to their complexity and high harm. In this paper, the method of dielectric barrier discharge (DBD) plasma coupled with iron-based catalyst (FeNC) activating periodate (PI) was first designed for ECs removal. The ingenious introduction of FeNC not only promotes the Fenton-like reaction of DBD system but also reduces the PI activation energy barrier and accelerates the electron shuttle between PI and pollutants.

The limited understanding of microbial response mechanism remains as a bottleneck to evaluate the long-term remediation effectiveness of in situ chemical oxidation in contaminated groundwater. In this study, we investigated long-term response of bacterial communities throughout five remediation stages of pre-oxidation, early-oxidation, late-oxidation, early-recovery and late-recovery. By analyzing bacterial biomass, taxa, diversity and metabolic functions, this work identified the consistently suppressed glyceraldehyde-3-phosphate dehydrogenase pathway and the enrichment of naphthalene degradation pathways for secondary products, suggesting persistent oxidation stress and enhanced microbial utilization of lower-molecular weight carbon sources at the oxidation and early-recovery stages.

A new in situ fracturing-enhanced oxidative remediation approach was recommended in this study to achieve rapid and efficient remediation of low-permeability contaminated sites. The objective of this study was to evaluate the effects of permeability and potassium permanganate (KMnO) concentration on the oxidation effectiveness and kinetics of KMnO in phenanthrene (PHE)-contaminated soil through rigid-wall hydraulic conductivity tests and a series of laboratory experiments. The results indicate that for various low-permeability contaminated soils, there was a critical KMnO concentration to significantly reduce the remediation time and a critical Darcy velocity to meet remediation goals.

The rapid advancement of nanotechnology, particularly in the realm of pharmaceutical sciences, has significantly transformed the potential for treating life-threatening diseases. A pivotal aspect of this evolution is the emergence of "green nanotechnology," which emphasizes the environmentally sustainable synthesis of raw materials through biological processes. This review focuses on the biological synthesis and application of zinc oxide (ZnO) nanoparticles (NPs) from probiotic bacteria, particularly those sourced from wastewater.
