Summary: This study investigated the aging effects of standard biochars on the remediation of metal(loid)-contaminated soil. Sewage sludge biochars showed the highest resistance to aging, likely due to their oxygen-containing functional groups and poorly-developed pore structures. The relationship between ash content and pyrolysis temperature, as well as the similarities in aging patterns of Cu and Sb, were also observed. The results provide insights into the long-term risks associated with managing metal(loid)-contaminated agricultural soils.

Summary: Customizing iron speciation in Fe-biochar is crucial for effective arsenic immobilization. Different iron speciations play distinct roles in As removal, with labile/amorphous-C inducing more reductive-Fe(0) formation leading to efficient As immobilization, while stable/graphitic-C generates more amorphous-Fe resulting in high As removal despite limited Fe(0) content. This study provides insights for the design of multifunctional Fe-biochar for environmental remediation.

Summary: This study investigated the effects of different pretreatments on the properties of biochar and its adsorption behavior for Pb2+. Biochar pretreated with water-washing and freeze-drying (W-FD-PB) exhibited the highest adsorption capacity for Pb2+ at 406.99 mg/g, compared to 266.02 mg/g for water-washing pretreated biochar (W-PB) and 188.21 mg/g for directly pyrolyzed biochar (PB). The enhanced adsorption capacity of W-FD-PB was attributed to the removal of potassium and sodium through water-washing, resulting in a relatively enriched calcium and magnesium content, as well as the disruption of fiber structure through freeze-drying, leading to a fluffy and highly porous surface during pyrolysis. Mechanism analysis revealed that cation ion exchange and precipitation were the driving forces in Pb2+ adsorption on biochar, and both mechanisms were enhanced on W-FD-PB. Additionally, the application of W-FD-PB in Pb-contaminated soil increased soil pH and significantly reduced the availability of Pb.

Summary: This article summarizes the ways microalgae cope with metal(loid) stress and their specific mechanisms of phycoremediation in AMD. The main mechanisms include biosorption, bioaccumulation, coupling with sulfate-reducing bacteria, alkalization, biotransformation, and Fe/Mn mineral formation. Several Fe/Mn mineralization mechanisms induced by photosynthesis, free radicals, microalgal-bacterial reciprocity, and algal organic matter are proposed. The comprehensive environmental effects of microalgal co-occurring and cyclical opposing processes must be carefully considered.

Summary: In this study, modified biochars with enhanced electrochemical properties were used to increase the remediation of PCP in soil. The effectiveness of the modifications varied under aerobic and anaerobic conditions, with the KMnO4 oxidation of an amorphous biochar pyrolyzed at 400 degrees C (B-KMnO4) showing the highest rates of remediation and removal of PCP in both conditions. The redox capacity of the biochar was found to be the primary factor determining the degree of remediation, while the conductivity and redox capacity both influenced the rate of remediation.

Summary: Asbestos is a group of silicate minerals that can lead to serious health risks when inhaled as respiratory dust, causing diseases such as mesothelioma and asbestosis. There is a large amount of in-situ asbestos-containing materials (ACMs) in the built environment, and it is not feasible to remove them completely. Therefore, containment, stabilization, and inertization or destruction are three approaches used for managing hazardous ACMs. Technologies such as thermal decomposition, bioremediation, and chemical treatment have been found effective in achieving safe disposal or recycling of ACMs.
