Summary: Cabbage grown in contaminated soils can accumulate high levels of arsenic, which poses serious health risks. The efficiency of arsenic uptake varies among different cabbage cultivars, and this study aimed to investigate the underlying mechanisms. By comparing low (HY) and high As accumulating cultivars (GD), it was found that HY showed reduced As uptake and reactive oxygen species (ROS) content, as well as increased shoot biomass, under low As concentration. At high As concentration, HY exhibited thicker root cell walls and higher protein content, which reduced arsenic damage and increased shoot biomass compared to GD. Therefore, factors such as higher protein content, root activity, and thickened root cell walls contribute to lower As accumulation in HY compared to GD.

Summary: This meta-analysis evaluates the effect of biochar application on soil cadmium (Cd) bioavailability using data from 84 peer-reviewed articles. The results show that biochar can reduce Cd bioavailability in contaminated soils, with the greatest reduction in urban/anthropogenically contaminated soils. The effect of biochar varies among soil types, and it is most effective in acidic or coarse- and medium-textured soils, but should be avoided in fine-textured soils.

Summary: In this study, the effects of functionalized biochars (PBC and FePBC) and different irrigation regimes (CF and IF) on rice yield and the accumulation of As and Pb in rice grain were investigated. The results showed that FePBC increased rice yield under both CF and IF conditions. The concentration of As in grain was higher under CF conditions, whereas the concentration of Pb was higher under IF conditions. Therefore, the application of multiple-functionalized biochar can effectively increase rice yield and reduce As accumulation, particularly under IF conditions, but it is not applicable for Pb remediation in paddy soils.

Summary: Biochar-derived dissolved organic matter (BDOM) plays important roles in soil ecosystem by influencing soil properties and providing nutrients to soil microbes. BDOM can either enhance or suppress the growth of certain soil microorganisms depending on its composition and labile organic compound content. This review focuses on the impact of BDOM concentration, feedstock biomass type, and pyrolysis temperature on soil microbial functioning, community structure, and enzymatic activity. Results indicate that feedstock type and pyrolysis temperature affect BDOM characteristics and its interaction with soil microbial communities. Plant-based biochar produced at lower pyrolysis temperatures often contains more aliphatic BDOM, while higher pyrolysis temperatures yield more aromatic BDOM. BDOM from plant biochar has higher specific ultraviolet absorbance (SUVA) and humification index (HIX) compared to manure-based biochar. The SUVA and HIX of BDOM positively correlate with total fatty acid methyl ester content, but negatively correlate with abundances of actinomycetes, arbuscular mycorrhizae, and fungal communities. However, long-term experiments are needed to fully understand the environmental fate of BDOM in biochar-amended soil and its interaction with soil organic matter and microorganisms.

Summary: Thermoacidophilic Cyanidiales have a competitive advantage in extreme metal-rich environments. Cyanidioschyzon merolae (Cm), Cyanidium caldarium (Cc), and Galdieria partita (Gp) were found to effectively remove hexavalent chromium [Cr(VI)]. Cm and Gp could remove 168.1 and 93.7 mg g-1 of Cr(VI) at pH 2.0 and 7.0, with a significant portion being reduced to trivalent chromium [Cr(III)]. The presence of Cr(OH)3 was observed and correlated with the high sorption capacity of Cm and Cc at pH 2.0. These findings suggest that Cyanidiales have potential for environmentally-friendly and sustainable remediation of Cr(VI).

Summary: In this study, hydrogen radicals were found to be a new pathway for the production of hydroxyl radicals, which increased the dissolution of cadmium sulfide and the solubility of Cd in paddy soils. Soil incubation experiments showed that the bioavailable Cd concentrations in flooded paddy soils increased by 8.44% after 3 days of aeration. The presence of hydrogen radicals in aerated soil sludge was observed for the first time. Electrolysis experiments confirmed the association of CdS dissolution with free radicals. The application of biochar decreased soil DTPA-Cd by 22-56% through multiple mechanisms, including the quenching of radicals and stimulation of Fe/S-reducing bacteria.

Summary: The conversion of organic matter and phosphorus during the composting process of vegetable waste is influenced by the addition of microbial inoculants. This study investigated the effects of straw-decomposing microbial inoculant (SDMI) on the stability of organic matter and activation of phosphorus in the composting of vegetable waste. The addition of SDMI promoted the degradation of dissolved organic carbon, improved phosphorus stability, and enhanced the thermal stability of organic matter. The results showed that stable forms of phosphorus, such as aluminum phosphate and iron-containing phosphate, were the main forms of phosphorus in the final compost. These findings provide a basis for producing high-quality vegetable compost products and improving the reutilization potential of vegetable waste.

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.
