Summary: Oil-contaminated soil is a concerning issue due to its potential harm to humans, animals, and the environment. Nanoparticles and surfactant foams have shown promise in remediation of oil pollutants in soil. This review evaluates the fate and transport of oil compounds, interaction between nanoparticles and surfactant foam, removal mechanisms, and factors affecting remediation efficiency, while highlighting the need for further research on soil types, cost, and post-treatment processes.

Summary: This study demonstrates the potential of the Fe0@C/surfactant system for in-situ contaminated site remediation. The use of surfactants promotes the desorption of pollutants, enhancing the contact between the reducing agent and the pollutants. Fe0@C shows better performance in reducing soil-adsorbed pollutants compared to conventional nZVI. However, the composite may be gradually passivated in the alkaline environment during the reduction process.

Summary: This review provides a comprehensive analysis of the effectiveness of surfactants in enhancing the remediation of contaminated soils. The study examines recent and older research on the use of surfactants for soil reclamation purposes and evaluates their potential benefits and limitations. Surfactants have shown great potential in enhancing the remediation of contaminated soils by improving the solubility and mobility of hydrophobic contaminants. However, the effectiveness of surfactant-based remediation methods depends on several factors, and further research is needed to optimize their use.

Summary: This simulation study investigates the feasibility of using foams as blocking agents in the remediation of NAPL-contaminated soils and groundwater. The results show that using foams for blocking is as effective, if not more effective, than using foams for mobility control, with oil recovery rates up to near 94.9%. This feasibility study focuses on vertical wells and serves as a stepping stone for further research on the use of horizontal wells in hilly terrain.

Summary: This study investigated the Electrokinetic Remediation (EKR) technique for removing lead (Pb) from artificially contaminated soils (1000 mg/kg Pb). The effects of operating parameters such as periodic voltage gradient, electrolyte amendments with ethylenediaminetetraacetic acid (EDTA) and a non-ionic surfactant (Tween 80), and type of electrode material were examined. The results showed that a high voltage gradient, EDTA as electrolyte, and stainless-steel electrodes were favorable for the overall Pb removal process.

Summary: This study established six different surfactant-enhanced microbial remediation treatments on petroleum hydrocarbon-contaminated soil. The results showed that rhamnolipid-enhanced Bacillus methylotrophicus remediation achieved the highest removal rate. The assembly process of bacterial communities was found to be impacted by deterministic factors, and a significant positive correlation was observed between the deterministic assembly process and the removal rate of petroleum hydrocarbons.

Summary: This study reveals that chronic exposure to PM induces chronic inflammation and development of COPD by dysregulating NAD+ metabolism and subsequent SIRT1 deficiency in pulmonary macrophages. Activation of SIRT1 by resveratrol effectively mitigates PM-induced inflammation and COPD development. Targeting metabolic and epigenetic reprogramming in macrophages induced by PM is a promising strategy for COPD treatment.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.

Summary: Ocean depth affects microbial diversity, composition, and co-occurrence patterns of microplastic microbial communities. Deterministic processes dominate the assembly of mesopelagic plastisphere microbial communities, while stochastic processes shape the assembly of bathypelagic microbial communities. The relationships between microorganisms in the mesopelagic layer are more complex and stable, with Proteobacteria and Actinobacteriota playing important roles.
