Summary: Earthworms have the potential to remediate soils contaminated with potentially toxic elements (PTEs), but thorough research and reviews on this topic are currently lacking. This review provides insights into the distribution and abundance of earthworms in PTEs contaminated soils, the influence of PTEs on earthworm communities, factors affecting earthworm PTEs accumulation and elimination, and the dynamics of PTEs in earthworm-amended soils.

Summary: This study compared the characteristics and environmental risks of potentially toxic elements (PTEs) in biochar obtained from animal manure pyrolysis at different reactors. Results showed that biochars from a pilot-scale reactor had higher potential ecological risk index. Biochars produced from fast pyrolysis at 400 degrees C had higher stability of PTEs compared to those produced from slow pyrolysis at a lab-scale reactor.

Summary: The study focused on using natural zeolite clinoptilolite to reduce the leaching rate of potentially toxic elements in soil from mine tailings. The zeolite was characterized and an ammonium-exchange method was employed for its treatment. Leaching experiments were carried out with polluted soil and zeolite mixtures, showing that the presence of zeolite reduced the concentration of Cd and Mn in leachates. The results suggest that natural zeolite clinoptilolite holds potential for reducing the leaching rate of potentially toxic elements in mine tailing soil.

Summary: This study examined the content, transfer pathways, and potential risks of potentially toxic elements (PTEs) in common crops from different farmlands surrounding an indigenous Zn-smelting area in Guizhou, China. The results showed that cabbage and radish at some sites had thallium (Tl) levels exceeding the maximum permissible level for food, while the edible portion of maize was not prone to Tl risk.

Summary: The presence of potentially toxic elements (PTEs) in marine sediments can have significant impacts on environmental quality and economic and recreational activities in related areas. This study thoroughly investigated the behavior of four PTEs (As, Hg, Pb, and Zn) in sandy foreshore sediments (SFSs) under different pH, redox potential, and temperature conditions of marine water. The results showed that released As was 2.7-6 times higher than its initial concentration, while Pb and Hg had preferential release in the liquid phase (up to 10% and 9.1%, respectively). Increase in Zn and Hg content in labile fractions of SFSs indicated their higher bioavailability after the tests. These findings provide valuable insights for predicting contaminant behavior in marine matrices and supporting environmental monitoring and preservation strategies.

Summary: In this study, water-soluble nanofibers of oseltamivir (OTV) were fabricated through electrospinning, and inclusion complexes (ICs) of OTV:beta-cyclodextrin (BCD) and OTV:hydroxypropyl-beta-cyclodextrin (HCD) were formed. The presence of ICs in the nanofibers was confirmed, and it was found that the ICs enhanced the release rate and water solubility of OTV, making them suitable for drug delivery system development.

Summary: The uptake of oxygen by materials during aging processes affects their mechanical properties and technical usability. To assess the kinetics of such processes and predict the service life of materials, quantitative experimental methods are needed to identify the underlying kinetic behavior. In this study, an oxidation stability test device is used to continuously measure the oxygen uptake by material samples, allowing artificial acceleration of the process. Correction procedures for temperature and pressure history are outlined for quantitative analysis on a wider time scale.

Summary: This study investigated the impact of oxygen transfer and uptake rates on xylonic acid production from xylose using Gluconobacter oxydans. Experimental results showed that under non-oxygen limitation conditions, the maximum specific oxygen uptake rate and xylonic acid production rate were approximately 18.0 mmolO(2)/g(x)/h and 6.0 g/g(x)/h, respectively. The findings also identified the minimum k(1)a value needed to prevent oxygen transfer limitation and ensure optimal cell activity.

Summary: The primary motivation of this study was to explore the energy potential of residual defatted microalgae biomass through anaerobic co-digestion with rice straw. The results show that co-digestion of microalgae with rice straw can significantly increase the cumulative biomethane yield, and the sludge obtained from anaerobic digestion can be reused for microalgae cultivation. Furthermore, the combination of microalgae and rice straw helps enhance energy recovery and provides a sustainable approach for the development of a microalgae-based biorefinery.

Summary: This study developed a synergetic and high-efficiency treatment of waste tantalum capacitors (WTCs) and polyvinyl chloride (PVC) using subcritical water process. The treatment significantly reduced the temperature and reaction time for metal tantalum recovery from WTCs, and improved the dechlorination efficiency of PVC. The optimized conditions resulted in 100% resin conversion efficiency of WTCs and 97.39% dechlorination efficiency of PVC. The interaction between decomposition products of WTCs and PVC produced a high level of benzoic acid.
