Summary: The addition of biochar can safely reduce the toxicity of heavy metals to plants, but further research is needed to clarify the relationship between soil properties and potential mechanisms. This study investigated the fractionation of Pb, Cd, Zn, and Cu in naturally contaminated soil amended with biochar and found that soil pH and organic matter play a significant role in the redistribution of these metals. The study suggests that biochar can be an effective tool in reducing the risk of heavy metals in contaminated soil.

Summary: This study investigated the biodiversity of streptomycete-like isolates from various technosols in Slovakia, identifying a potential new species within the Crossiella genus and at least one possibly new species within the Streptomyces genus. Some isolates showed high resistance to heavy metals, with lead being the most tolerated metal. The results suggest that technosols could be a promising source of new actinomycete species with bioremediation potential.

Summary: The quality of groundwater in the Jaunpur district of Uttar Pradesh, which is the only source of water for drinking and irrigation, has been poorly studied. This study evaluated the groundwater's suitability for drinking and irrigation using various chemical parameters. The findings revealed that most of the groundwater samples had high levels of EC, TDS, and TH, indicating unsuitability for drinking and irrigation. The study suggests that the groundwater in the area should be treated before drinking. However, it is suitable for irrigation.

Summary: This study investigated the fate of lead in contaminated soil treated with cement and proposed that the main mechanism involved in lead retention is its incorporation and/or adsorption on calcium silicate hydrates and ettringite. The research used synchrotron-based X-ray absorption spectroscopy to probe the transformation of lead environment in the real contaminated soil after stabilization, providing valuable insights into the stabilization mechanisms.

Summary: This study collected 12 fly ash samples from 9 grate power plants in southeastern China and determined their PCDD/Fs and heavy metal concentrations, comparing them to previous data. The results showed that the PCDD/Fs concentration in fly ash ranged from 0.002-0.051 ngI-TEQ/g, with an average of 0.027 ngI-TEQ/g. The study also identified a strong correlation between toxicity and specific PCDDs. Additionally, the heavy metal Pb was found to pose a significant environmental risk.

Summary: Computational multiscale methods have been used in engineering problems to analyze and derive constitutive responses, but their application in a nonlinear framework may be limited by high computational costs, numerical difficulties, and inaccuracies. A hybrid methodology combining classical constitutive laws, data-driven correction, and computational multiscale approaches is presented in this paper. This approach improves the versatility and accuracy compared to classical model-driven or purely data-driven techniques.

Summary: This study demonstrated the suitability of biodegradable complexing agents for treating soil contaminated with heavy metals using electrokinetic remediation. Sodium alginate (SA) significantly improved the removal efficiency of Cu2+ and Zn2+, while chitosan (CTS) could complex metal ions and form crosslinked CTS gelations, migrating to the catholyte under the electric field.

Summary: This paper discusses the status of heavy metal pollution in agricultural fields and the research progress of removal technologies, and provides an analysis and comparison of remediation technologies from three aspects: physicochemical, electrochemical, and biological. The results show that the morphology of soil heavy metals is an important reference for selecting remediation methods, and phytoremediation and magnetic biochar removal of heavy metals show great potential for development.

Summary: In this study, a combination of electrokinetic and chemical immobilization was used to remediate Cd and Pb polluted river sediments. The immobilization ratios for Cd and Pb were achieved by adjusting the concentrations of the immobilization reagents and the applied voltage. The enhancement effect of the electric field is mainly due to the increased contact between the immobilization reagents and the heavy metals.

Summary: The existing spatial interpolation methods in the prediction of soil heavy metal distribution are limited by their reliance on spatial auto correlation theory, which fails to consider pollution patterns. This paper proposes a method that integrates Geodetector, Co-Kriging (COK), and partition interpolation to incorporate diffusion patterns of pollutants, resulting in improved prediction accuracy.

Summary: This study investigated the association between ambient PM2.5, O3 pollution, and ovarian reserve in reproductive-aged Chinese women. The results showed that increased exposure to PM2.5 and O3 was associated with decreased AMH levels, indicating reduced ovarian reserve. Notably, the effects of O3 exposure on ovarian reserve were different from those of PM2.5 exposure.

Summary: Systemic insecticides and rising temperatures have combined effects on the abundance of Odonata nymphs in paddy fields. The standalone effect of insecticide exposure decreased the Odonata community, while nymphs decreased synergistically with temperature rise in paddy water. However, the impacts of each stressor alone varied among species.

Summary: The Arctic region is facing contamination from long-range pollution and local human activities. Polycyclic Aromatic Hydrocarbons (PAHs) are used as environmental indicators for emission, transport, and deposition processes. Research conducted in the Arctic surface snow in Ny-Ålesund, Svalbard from October 2018 to May 2019 shows that long-range inputs of PAHs mainly occur in winter, while the most abundant analyte retene exhibits opposite seasonal trends.

Summary: In this study, a human physiologically based pharmacokinetic (PBPK) model of diethyl phthalate (DEP) was developed to assess its toxicity. The model considers the distribution and metabolism of DEP and its active metabolite monoethyl phthalate (MEP) in different tissue compartments. Sensitivity analysis and Bayesian Markov chain Monte Carlo (MCMC) simulations were performed to evaluate the uncertainty and variability of the model parameters. The results suggest that dermal absorption is an important route of exposure to DEP in the environment.

Summary: This study investigates the feasibility and mechanisms of a chemical-free nanobubble-based AOP for treating organic micropollutants in water. The results show that the oxygen nanobubble AOP has a significantly higher removal efficiency compared to air and nitrogen nanobubbles. The treatment performance is not affected by pH and the presence of ions. Higher initial concentrations of the micropollutant lead to slower treatment processes, but similar removal performance is achieved in the end. The presence of organic matter reduces the removal rate of the micropollutant. The results have practical feasibility for water and wastewater treatment.

Summary: This study investigates the impact of biochar on methylmercury (MeHg) accumulation in rice. The results show that biochar reduces MeHg levels in paddy soils by decreasing bioavailable Hg and microbial Hg methylation. Additionally, biochar decreases the uptake and translocation of MeHg in rice plants, resulting in a reduction of MeHg accumulation in rice grains.

Summary: The synergistic effects of trace sulfadiazine and cast-iron corrosion scales on the formation of disinfection by-products in drinking water distribution systems were investigated. The presence of magnetite resulted in increased concentrations of DBPs due to the higher microbial activity and enhanced microbial extracellular electron transport pathway. The study highlights the importance of considering trace antibiotics pollution and corrosion scales in water sources for DBP control.

Summary: This study aims to explore the effects of thiencarbazone-methyl center dot isoxaflutole on soil microflora and the potential mitigation mechanisms to bacterial communities. It was found that increasing the application of thiencarbazone-methyl center dot isoxaflutole resulted in increased stress on soil bacterial community structure and diversity. Increasing soil pH was recognized as a key factor in improving the diversity and structure of soil microflora. Supplemental use of nitrapyrin or modified attapulgite can increase soil pH and improve bacterial diversity.
