Summary: In this study, geotextiles were used as superabsorbent geotextiles to decontaminate soil polluted with crude oil. The ability of these geotextiles to absorb oil is better than that of absorbing water. The removal efficiency of the absorbent geotextile was evaluated, and the shear strengths of the decontaminated soil samples were compared with those of contaminated soil through direct shear tests.

Summary: Biodegradation of toxic chlorophenols and crude oil was analyzed using the composite microbial agent B-Cl, composed of Bacillus B1 and B2. The study assessed the biodegradation mechanism of B-Cl through whole genome sequencing, Fourier transform infrared spectroscopy, and gas chromatographic analyses. B-Cl proved to be effective in reducing Cl- concentrations and crude oil biodegradation, and in reconstructing soil microbial communities for the degradation of various compounds. The presence of 2,4-DCP was found to hinder the observed effects. This study highlights the importance of using B-Cl for in-situ bioremediation of chlorophenols and oil-contaminated soil.

Summary: We prepared SA/GO/C5 immobilized gel pellets by embedding efficient crude oil degrading bacteria Bacillus C5 in the SA/GO composite material. The addition of SA/GO/C5 significantly promoted the removal of crude oil in soil, reaching 64.92% after 30 days, which was 2.1 times the removal rate of C5. The study demonstrated that SA/GO/C5 is an effective method for remediating crude oil-contaminated soil.

Summary: The study investigates the aging effect on oil-contaminated soil by analyzing its properties and desorption behavior. XPS, FT-IR, SEM, and BET techniques are used to study the oil-soil interactions and pore-scale effect. The research reveals that aging enhances the oil-soil interactions and pore-scale effect. The desorption mechanism of oil from aged soil is elucidated, with surface desorption and intraparticle diffusion being the major steps.

Summary: The study focuses on the application of a novel biochar (SSBC) generated from waste rice straw and municipal sludge using ZnCl2 activation method in persulfate (PS)-based remediation for crude oil in soil. The SSBC-PS oxidative system showed a high efficiency of 69.11% in crude oil degradation. The SSBC had superior properties compared to sludge biochar, including a higher surface area, pore volume, and pore surface area. The presence of surface functional groups in SSBC contributed to its good PS activation performance. Furthermore, the SSBC-PS system promoted the growth of potential crude oil degraders and facilitated the degradation of organic pollutants.

Summary: Bioaugmentation and biostimulation synergistic remediation using the combination of composite microbial agent TY and dehydrocoenzyme activator is an effective strategy for the bioremediation of oil-contaminated soil. This combination system significantly enhances the degradation rate of crude oil, reaching 79.44% after 60 days. Gas chromatography analysis shows its efficiency in targeting the degradation of specific oil fractions. High-throughput sequencing reveals the dominant genera in the soil and PICRUSt analysis demonstrates the increased abundance of genes associated with crude oil degradation. Overall, the combination system of compound bacterium TY and dehydrocoenzyme activator shows great potential for oil-contaminated soil bioremediation.

Summary: Petroleum refineries produce oily sludge containing hazardous polycyclic aromatic hydrocarbons (PAH), and its proper disposal is a major concern. Analyzing the physicochemical properties and functions of indigenous microbes at contaminated sites is crucial for determining the bioremediation strategy. This study examines these parameters at two geographically distant sites with different crude oil sources and compares the metabolic capability of soil bacteria based on contamination sources and site age. The results show that petroleum hydrocarbon-derived organic carbon and total nitrogen negatively impact microbial diversity.

Summary: By impregnating clays with non-toxic transition metals (iron or copper), this study demonstrates that the pyrolytic treatment temperature and time for crude-oil contaminated soils can be decreased. The addition of metal-impregnated clays significantly enhanced the removal efficiency of total petroleum hydrocarbons (TPH). It is postulated that the transition metals catalyzed the pyrolysis reactions at lower temperatures. This work provides proof of concept for the use of metal-impregnated clays in enhancing the rapid pyro-catalytic treatment of contaminated soils.

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.

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.
