Summary: This article provides a comprehensive review of aerobic composting technology for remediating soil contaminated with total petroleum hydrocarbons (TPHs). The studies show that composting can successfully treat TPH contamination in various types of soils, with removal efficiencies as high as 99%. Factors such as soil type, oxidation reactions, and biodegradation rates are key to the composting process and need to be monitored and controlled for successful degradation.

Summary: This study compared the influence of different aerobic conditions on polycyclic aromatic hydrocarbons (PAH) degradation and found that biostimulation (BS) successfully stimulated the growth of indigenous bacteria in soil. The results obtained from XAD-4 extraction showed a good correlation with the degraded amounts, suggesting that XAD-4 extraction could be a simplified, easier, and lower cost method for bioavailability assessment.

Summary: Hydrocarbon spills in groundwater can lead to changes in geochemical conditions, potentially releasing geogenic contaminants. This study found that radium activities were up to 10 times higher in an aquifer contaminated with a mixture of chlorinated solvents, ketones, and aromatics. The elevated radium activities were likely due to iron and manganese (hydr)oxide reduction and sorption site competition within the dissolved phase plume. However, within the Fe(III)/SO4 (2-) reducing zone downgradient from the source, radium activities returned to background levels.

Summary: Vegetable production systems are found to have significant impacts on N2O emissions and antibiotic pollution. This study reveals that the growth of vegetables can reduce N2O emissions while the contamination of enrofloxacin increases N2O emissions. By interacting with soil nitrate and certain bacteria, growing vegetables can either decrease the production of N2O or increase the consumption of N2O, resulting in lower N2O emissions.

Summary: In this study, it was found that the biodegradation rates of benzene and BaP co-contamination were significantly enhanced at elevated temperatures, with increased bioavailability and generation of ROS. The study also revealed that gram-positive bacteria exhibited higher enzymatic activities and PAH-RHD alpha gene expression, indicating their preference for long-term elevated temperatures. ROS species (O(2)(center dot-)and center dot OH) were detected and cleared by increased antioxidant enzyme activities. Soil properties were affected by temperature treatments, indicating metal-organic-associated reactions during TEB. Overall, the results highlight the importance of temperature in enhancing biodegradation under thermally enhanced biodegradation conditions.

Summary: This study investigated the use of graphene oxide-immobilized bacterial pellets for the removal of polycyclic aromatic hydrocarbons (PAHs) from contaminated soil. The results showed that these immobilized bacterial pellets significantly improved the removal rate of PAHs and enhanced the abundance of degrading bacteria in the soil. They also enriched potential indigenous degrading bacteria and functional genes involved in PAHs degradation. Overall, this nanocomposite bacterial pellets provide a novel microbial immobilization option for remediating organic pollutants in harsh soil environments.

Summary: Biochar derived from Enteromorpha prolifera can reduce the bioavailability and transfer of chromium (Cr) from soil to plants, leading to decreased phytotoxicity. In roots and stems, Cr mainly exists in low-toxicity forms, such as bound state and protein complexes. The subcellular detoxification processes differ in roots and stems, with Cr mainly being distributed in cell walls and vacuoles.

Summary: Stress-associated dysbiosis of the microbiome can result in different configurations, which can change due to alternating selective forces. Our study suggests that while dysbiosis leads to different microbial communities in terms of beta diversity, they are not necessarily differently dispersed. Instead, dysbiosis leads to disrupted networks within the microbiome. Additionally, nutrient restriction can lead to changes in the compositional diversity and network interaction properties of the gut microbial communities.

However, the development and evaluation of these models are challenging due to difficulties in model setup, computational cost, and obtaining high-resolution data. This paper aims to review and compare different spatially resolved environmental models, with a focus on spatial multimedia fate models, to better understand their strengths and limitations. The review also highlights requirements for further improvement and integration of existing models.

Summary: Polycyclic Aromatic Hydrocarbons (PAHs) are important pollutants mainly emitted from incomplete combustion of organic materials. They exist in high concentrations in cities and contaminate air in both gas and particle form. Using plants to capture PAHs is an effective measure to mitigate pollution. This study found variations in PAH uptake and enrichment ability among different conifer species, providing equations to fine tune the reduction of PAH concentrations in air by adjusting plant biomass.

Summary: Temperature has a significant impact on the adaptation and composition of microbiomes, and their enzymes play a crucial role in the thermal response. This study demonstrates that enzyme thermal properties not only explain microbial thermal plasticity but are also finely tuned by the thermal variability of the environment. The findings highlight the importance of temperature-driven enzyme selection in shaping microbiome thermal plasticity and emphasize the need to consider thermal variability in addition to mean annual temperature in understanding microbial community response to temperature.

Summary: Two new classes of PCB metabolites, sulfonated-polychlorinated biphenyls (sulfonatedPCBs) and hydroxy-sulfonated-polychlorinated biphenyls (OH-sulfonated-PCBs), have been recently discovered. They are more polar than their parent compounds, but little is known about their chemical identity, ecotoxicity, or toxicity. This study provides the first evidence on the fate of these metabolites in the environment and presents results from various experiments to evaluate their soil partition coefficients, degradation after rhizoremediation, uptake by plants and earthworms, and an analytical method for extracting and concentrating these compounds from water.

Summary: This study investigates the induction and resuscitation of viable but non-culturable (VBNC) state in four Vibrio strains in cold seawater, as well as their response to hydrogen peroxide-induced oxidative stress. The results show that VBNC state leads to phenotypic changes in the cells, causing a loss of ability to grow on solid media, which can be partially or fully reverted upon resuscitation. Low concentrations of hydrogen peroxide can prevent cell resuscitation, while prolonged exposure to hydrogen peroxide, even at concentrations lower than inhibitory levels for log-phase growth, permanently damages VBNC cells.

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.

Summary: This study investigated the presence of aluminum in human colon cancer samples and its potential association with biological processes involved in cancer progression. Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
