Summary: The study investigated the effect of an ex-situ soil washing technique using EDTA on contaminated soil. The results showed a significant reduction in total and bioavailable metal fractions, but they did not meet the guideline values. The addition of organic amendment further reduced heavy metal uptake in vegetables, resulting in acceptable levels according to EU guidelines for food safety. The study also found that the increase in soil pH and nutrient availability led to higher vegetable yields.

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: 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: The study revealed that agricultural soils and vegetables in Ahvaz metropolis are moderately polluted with heavy metals and PAHs. Results suggested that heavy metals may come from anthropogenic sources, while PAHs are mainly from gasoline, diesel exhaust, and herbicide usage. Additionally, findings indicated that local residents may face increased cancer risks through consumption of contaminated vegetables.

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: 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.
