Summary: Soil heavy metal pollution is a serious threat to the eco-environment. Municipal sludge-based passivators and clay minerals have been widely applied for immobilizing heavy metals in soils. However, little is known about the immobilization effect and mechanisms of raw municipal sludge and clay in reducing the mobility and bioavailability of heavy metals in soils.

Summary: In this study, composite repair material was obtained through composting and fermentation of straw biochar and sludge, and its remediation effect on soil heavy metals copper and lead was investigated. The results showed that the addition of remediation materials effectively reduced the content and effectiveness of heavy metals in the soil and promoted the change of Cu and Pb morphology in the heavy metal-contaminated soil, thus achieving the remediation of the heavy metal-contaminated soil.

Summary: Heavy metals in wastewater and soil are a serious threat to the environment and human health. This study adopted a unique method to improve the adsorption performance of MnO2 by tailoring its hollow mesoporous structure (HMN). The unmodified HMN showed good stability under acidic conditions and was directly used for adsorption and fixation of heavy metals. The adsorption capacity of HMN was significantly improved compared to other MnO2 adsorbents, and it showed promise for the purification of environmental water samples.

Summary: Arsenic-containing wastewater and arsenic-contaminated soil can cause serious environmental pollution. In this study, a new phosphogypsum-based passivate (Ca-mPG) was prepared using partial mechanical activation of calcium oxide, and its remediation performance on arsenic-contaminated soil was evaluated. The results showed that the passivate had an adsorption capacity of 37.75 mg/g, and it effectively reduced the leaching concentration of arsenic in the contaminated soil to below the Chinese national standard. It also showed excellent passivation effect on other heavy metals. Furthermore, the study found that the combination of As-resistant bacteria and passivators promoted the stabilization effect of contaminants during soil remediation. Overall, this study demonstrates an eco-friendly waste-soil remediation strategy for HM-contaminated soils.

Summary: The accumulation of toxic and persistent lindane in soil landfills poses a risk of leaching and contamination of surrounding rivers. A simple and cost-effective composite consisting of magnesium oxide (MgO) and activated carbon (AC) has been proposed to remove lindane in soil and water. The use of MgO provides a basic pH and allows for the total adsorption of heavy metals in contaminated soils, while AC provides sites for lindane adsorption and a reductive atmosphere. This composite has shown highly efficient remediation capabilities, allowing for the elimination of lindane and immobilization of heavy metals.

Summary: In this study, an inexpensive and ecofriendly mould made from bentonite clay and Samne Ghat soil was used to remove heavy metals from water. The surface of the mould contained functional groups that facilitated the adsorption of metal ions, and the mould itself was thermally stable and negatively charged. The experimental results showed that the adsorbent surface achieved monolayer coverage, and a genetic algorithm provided high efficacy.

Summary: This review explores the applications of natural polymers in environmental remediation, focusing on their performance in water treatment, soil decontamination, and reduction of atmospheric particulate matter. The potential of nanocomposite polymers as sustainable materials for integrated products is also discussed. Natural polymers, derived from renewable resources, offer high surface area, porosity, and adsorption properties, but future considerations include scaling up production, nanoparticle toxicity, and competition with food production.

Summary: Contaminated soil containing toxic metals and metalloids is a global issue that poses risks to ecosystems and human health. Over the past few decades, various remediation techniques, including chemical, biological, physical, and integrated approaches, have been adopted to address this pollution. In recent years, in situ metal immobilization, plant restoration, and biological methods have emerged as the best solutions for removing metals from soil.

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.
