Summary: The use of slag in PTE-contaminated soils can reduce the toxicity in plants, improving growth, yield, and quality of crops. However, the effectiveness of slag is influenced by factors such as plant species, growth conditions, stress duration, and type of slag used. This review emphasizes the potential of slag-based fertilizers in enhancing plant tolerance to PTE toxicity and provides a theoretical basis for their application in PTE-contaminated environments worldwide.

Summary: The concentrations of 26 elements in imported and domestic infant cereals were evaluated and risk assessment was performed based on the measurements. For toxic elements, Cd and Pb had exceedance rates of 20% and 16.7% respectively, and all toxic elements showed ingestion risk. For potentially toxic elements, no detectable levels were obtained for Be, Co, Ga, Sb, and Tl. Only 10% of the samples indicated a potential health risk from long-term intake of Al. Despite better performance of domestic samples in essential elements like Na, Ca, and Zn, none of the elements fully met the intake requirements. The standards for complementary foods for infants and young children are not sufficiently regulated, and infant cereals as the first weaning food should receive more attention in terms of safety and nutritional properties, especially the potentially toxic elements.

Summary: In this study, X-ray Absorption Spectroscopy (XAS) was used for the first time to investigate the speciation of zinc, lead, copper, and arsenic in Pb/Zn smelter slag. The XAS analysis revealed that zinc was mainly present in glass, ZnS, and possibly solid solutions with Fe oxides, while lead was mainly present in glass and apatite minerals. Copper was mainly speciated as Cu2S, with some metallic Cu and a weathering product, Cu(OH)2. Arsenic speciation was likely dominated by arsenic (III) and (V) oxides and sulfides. X-ray fluorescence analysis showed that the concentrations of zinc, lead, copper, and arsenic in the slag were 8.4%, 1.6%, 0.48%, and 0.45% respectively.

Summary: This study investigated the changes in physicochemical properties, ion composition, concentration, and ratio of soluble and insoluble potentially toxic elements (PTEs) in Moscow precipitation before, during, and after the lockdown period. The impact of the lockdown on precipitation composition was found to be both positive and negative. The decrease in precipitation pollution with PTEs was attributed to the purification of the atmosphere, while air advection from suburban areas contributed to the growth of insoluble PTEs. After the lockdown, the restoration of precipitation pollution by PTEs occurred gradually.

Summary: Protection and appropriate management of forests are crucial for climate change adaptation. Biochar amendments have the potential to improve forest soils, but their long-term effects have not been extensively studied. Relict charcoal hearths (RCHs) provide valuable data on changes in soil properties over several hundred years. Forest soils with biochar amendment show increased base cations, alkaline pH, and reduced bulk density, which is particularly beneficial for hostile environments. However, sites with favorable conditions may not see significant improvement or could be adversely affected.

Summary: This study compares the mobility of chromium (Cr) in two soils with different sources of Cr. It finds that anthropogenically contaminated soil leaches out more Cr compared to serpentine soil. The study demonstrates that naturally enriched sites with elevated Cr levels originating from bedrock are more resistant to Cr leaching than anthropogenically contaminated soils. The possible causes of these differences are discussed in the study.

Summary: The current study uses two cadmium datasets (legacy data and preferential sampling-legacy data) and auxiliary datasets from Sentinel-2 and Landsat-8 bands to assess and predict cadmium concentration in agricultural soil. The study is divided into two contexts: using legacy data, ensemble models, and different spatial resolutions of Sentinel-2 and Landsat-8 (context 1), and using preferential sampling-legacy data, ensemble models, and the same spatial resolutions (context 2). The results show that the combination of preferential sampling-legacy data and Sentinel-2 with ensemble models is the most appropriate and best approach for cadmium prediction in agricultural soil.

Summary: The accuracy of environmental risk assessment depends on selecting appropriate matrices for extracting contaminant(s) from soil. In this study, chelatants EDTA and tartaric acid were used to extract metal-contaminated soil, and Pistia stratiotes was used as an indicator plant to measure metal accumulation. Speciation modeling was employed to understand the geo-chemical mechanisms affecting matrix and metal-specific uptake. The study shows that different extractions have varying impacts on metal uptake and translocation, highlighting the importance of metal-specific speciation for accurate risk assessment.

Summary: This study evaluates the performance of ozonation and adsorption as in-series processes compared to standalone processes for the removal of Contaminants of Emerging Concern (CECs) in drinking water. The combination of both processes proves to be more effective than adsorption and ozonation alone. Ozonation improves the adsorption performance of poorly-oxidizable CECs but worsens that of well-oxidizable compounds. This research highlights the importance of considering both processes in the removal of CECs in drinking water treatment plants.
