Summary: Increasing pollution caused by inappropriate anthropogenic activities and industrialization has raised concerns about general health. Bioremediation is considered as the most efficient, economical, and environmentally friendly method for treating polluted environments. Microorganisms play a crucial role in detoxifying harmful pollutants by degrading, mineralizing, and transforming them into less toxic forms. Different bioremediation techniques have their own advantages and limitations based on the characteristics and location of the pollution. This review analyzes various bioremediation methods for organic pollutants from soil/sediments and wastewater, and explores emerging technologies that can enhance the efficiency of bioremediation. The integration of these technologies with existing bioremediation facilities is changing the landscape of environmental remediation towards sustainability.

Summary: Reclamation of pesticide contaminated sites, especially agricultural soil and pesticide manufacturing sites, has been challenging. Microbial bioremediation is an ecofriendly strategy for soil reclamation, but its large-scale field application faces challenges due to the varying interaction of microbes with polluted soil under different climatic conditions. Addressing challenges and employing interdisciplinary approaches can make microbe assisted bioremediation the preferred method for reclamation of pesticide contaminated sites.

Summary: The uncontrolled use of chemicals, urban wastes, nuclear resources, mining, petrochemicals and disposal of sewage sludge have led to rapid industrialization and severe heavy metal contamination of soils and waterways. Both inorganic and organic pollutants can impact the composition and functionality of soils, posing a threat to food security and human health. Remediation, such as Enhanced Natural Attenuation (RENA), using natural products from plants or microbes, is necessary to detoxify the environment and restore its productivity. This review discusses the technology, microbes, mechanism, challenges, and recommendations associated with RENA for a sustainable environment.

Summary: The application of parathion in agriculture can contaminate soil and harm soil environment. It is important to monitor parathion residues and assess their toxicity on soil health. The dissipation of parathion in tested soil followed a linear trend, with half-lives ranging from 5.6 to 56.8 days. Parathion pollution negatively affected FDA hydrolase activity and microbial biomass carbon, and their responses were influenced by both parathion dose and incubation time.

Summary: Soil phosphatase activity is sensitive to arsenic pollution and can be used to estimate arsenic toxicity in soil. This study investigated the effect of phosphorus addition on arsenic desorption and its toxicity to acid phosphatase. The results showed that phosphorus application increased arsenic desorption ratio and bioavailability in soil. Phosphorus addition significantly reduced soil acid phosphatase activity under all phosphorus concentrations but increased it in the soil with minimum arsenic content. The study also highlighted the importance of controlling phosphorus fertilizer applications in silty soils with acid and neutral pH to prevent increased arsenic mobility and toxicity to soil acid phosphatase.

Summary: This study investigates the degradation and conversion of PFAS in contaminated soil during the firefighting process by exposing the soil sample to high temperatures. The research finds that PFAS precursors, non-C-F bonded PFAS, PFCA, and PFSA can all be degraded under high temperature conditions. A 2D Gaussian surface is used to fit the concentration dependence of PFAS on temperature and time, providing a visual representation of the complex thermal kinetic process. This study offers a simple approach for monitoring and optimizing the thermal treatment of PFAS-contaminated soil.

Summary: Earthworms are being studied for their potential in bioremediation due to their impact on pollutant fate. Different earthworm species have varying sensitivities and capacities to break down contaminants, and Lumbricus terrestris is the most suitable species for bioremediation of OP-contaminated soil due to its higher levels of detoxification enzymes and oxidative homeostasis mechanisms compared to Eisenia fetida andAporrectodea caliginosa. These findings suggest L. terrestris as a better candidate for soil bioremediation than epigeic earthworms.

Summary: The presence of microplastics and nanoplastics in soils in agroecosystems is widespread and poses a threat to the food web. The effects of these particles on soil and its biota depend on various factors and are difficult to compare due to differences in sampling, detection, and categorization techniques. Agricultural soils serve as reservoirs for chemicals and contaminants, and understanding the sources, fate, and impacts of microplastics and nanoplastics in these soils is crucial for future research and regulatory guidelines.

Summary: Our study examined the anaerobic microbial degradation of hazardous polycyclic aromatic hydrocarbons (PAHs) and found that sulfate-reducing bacteria (SRB) in contaminated freshwater sediments can effectively degrade three-ringed phenanthrene and highly recalcitrant four-ringed pyrene. Desulfovibrio was the dominant bacterium in the phenanthrene-degrading culture, while Rhodopseudomonas was a significant member in the pyrene-degrading culture. This research indicates that SRB could play a crucial role in the natural attenuation of PAHs in oxygen-depleted freshwater sediments.

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.
