Summary: This study investigated the remediation of arsenic-contaminated abandoned mine soils. Oxalic acid was found to be the most effective washing reagent. Washing reduced the leachability and bioaccessibility of arsenic and iron in the treated soil, but it still exceeded the remediation criteria. Soil washing and subsequent solidification/stabilization could be an alternative option for remediating extremely contaminated abandoned mine soils.

Summary: In this study, a composite washing agent consisting of dithionite and tartaric acid was used to efficiently remediate arsenic-contaminated soils. The combination of these two compounds showed a synergistic effect, with dithionite promoting the dissolution of iron oxides and tartaric acid releasing some specifically adsorbed arsenic. The formation of Fe-TA complexes prevented the formation of new iron mineral phases and allowed for the release of more iron oxide-bound arsenic.

Summary: High concentrations of arsenic and antimony contamination in soil pose a potential risk to the ecological environment and human health. This study utilized Aspergillus niger fermentation broth as a washing agent to effectively remove As and Sb from polluted soil. The results showed that oxalic acid played a significant role in the removal process. Batch experiments determined the optimal conditions for the removal rate of Aspergillus niger fermentation broth. After three cycles of washing, the removal rates for arsenic and antimony were significantly high. The black Aspergillus niger fermentation broth exhibited great potential as a washing agent for the remediation of As and Sb-contaminated soils.

Summary: This study aimed to evaluate the effects of farmyard manure (FYM) on soil arsenic behavior and subsequent crop yield. The results showed that FYM supplementation decreased the water soluble and labile forms of arsenic in soil, while increasing the fixed forms. Additionally, FYM reduced the bioaccumulation of arsenic in plants and improved crop yield.

Summary: This study evaluated the Sb bioavailability and accumulation in wheat before and after remediation using composted manure and a chemical amendment. The results showed that poultry and sheep composts increased the residual fraction of Sb in soils and decreased its uptake by wheat, while the addition of limestone did not significantly affect the residual fraction of Sb. The study concluded that the addition of amended materials, especially poultry compost, significantly decreased the uptake of Sb in contaminated soils.

Summary: This study evaluated the use of ethylenediamine N,N'-disuccinic acid (EDDS) and 3-hydroxy-2,2'-imino disuccinic acid (HIDS) as alternatives to ethylenediaminetetraacetic acid (EDTA) for treating arsenic-contaminated excavated soil. The effectiveness of chelators in removing arsenic was optimized by adjusting various washing variables. Additionally, methods for immobilizing eluted arsenic and suppressing subsequent leaching were assessed.

Summary: Plant-soil interactions play a crucial role in the availability of arsenic and nutrients in arsenic-contaminated soils, affecting the uptake, tolerance, and leaching of arsenic in plants. The availability of arsenic was higher and nutrient content was lower in coarse-textured soil, resulting in greater arsenic uptake, lower biomass, and higher leaching of arsenic from the soil. Pteris vittata hyperaccumulated arsenic from coarse-textured soil, but not from medium-textured soil. Arsenic uptake by the fern was always greater than the loss through leaching.

Summary: Soil arsenic fractionation and bioaccessibility are crucial in human health risk assessment. This study demonstrated that As associated with amorphous and crystalline Fe/Al (hydr)oxides primarily contributes to increased bioaccessibility in human colon microbiota. The transformation of As differed between soils with high and low bioaccessibility, with liquid-phase As predominant in the former and solid-phase transformation in the latter.

Summary: Understanding the distribution and speciation of arsenic (As) associated with iron (Fe) in subsoil profiles is important for predicting the immobilization of high geogenic As and safe utilization of As-containing soil during land development. This study investigated the As enrichment mechanisms in four subsoil cores from Hong Kong using sequential chemical extraction and X-ray absorption near edge spectroscopy. The results showed that the subsoil profiles had relatively high concentrations of As, mainly in the form of As(V) associated with the residual fraction. Poorly crystalline Fe (oxyhydr)oxides played a key role in immobilizing most of the high geogenic As.

Summary: The oxidation of Cr(III) by birnessite (delta-MnO2) has significant impact on the toxicity and mobility of dissolved Cr(III) in soils. The presence of Fe and Al oxides coating on delta-MnO2 hinders the oxidation process. The oxidation of Cr(III) by delta-MnO2 follows a two-phase model and is influenced by the diffusion and adsorption of Cr(III) on electron-accepting sites.

Summary: The determination of the authenticity of extra virgin olive oils (EVOOs) has gained increasing interest, especially in Italy, which has the highest number of Protected Designation of Origin (PDO) oils in Europe. This study focused on using the inorganic content and electrochemical properties as markers to identify the region of origin and plant species of EVOOs. The results showed that the inorganic composition can be a useful marker for the geographical origin of EVOOs, while the voltammetric analysis can effectively distinguish the plant species of origin. This method could also be used to monitor the conservation status of the oils.

The analysis reveals that urban activities and soil/road dust resuspension are the main contributors to metal pollution. Although Biella has lower pollution levels than Turin, the daily average concentration of PM10 frequently exceeds the European limit value.

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.

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.
