Summary: Laboratory experiments were conducted to investigate the toxicity of antimony (Sb) to earthworms in four different agricultural soils. The earthworms clearly avoided the Sb spiked soils, and the avoidance response was correlated to the exposure dose. Different toxic effects of Sb were observed in the four types of soils, with antimony being more toxic in sandy alkaline soil. The study provided comprehensive data on the toxicological effects of Sb in agricultural soil, which can contribute to ecological risk assessments.

Summary: In alkaline wastewater with high arsenic concentration, traditional lime precipitation generates large amounts of hazardous waste. In this study, a heat-activated reduction method using thiourea dioxide (TDO) was proposed to efficiently remove and recover arsenic from alkaline wastewater. More than 99.9% of As(III)/As(V) were reduced to As(0) with a purity of more than 99.5 wt% by TDO within 30 min. The highly reductive eaq -and SO2• radicals generated during TDO decomposition significantly contributed to the arsenic reduction. Increasing pH and temperature improved the arsenic reduction by accelerating the formation of eaq -and SO2• radicals. Dissolved oxygen had a negative effect on arsenic removal, while CO32- slightly suppressed the removal effect. SiO32-, PO43-, Cl-, SO42-, and NH4+ had negligible effects. This method has potential for efficient arsenic removal and reduction in alkaline wastewater.

Summary: Sole O2 or H2O2 oxidants are insufficient for oxidizing Sb(III) over a time scale of hours to days, but Sb(III) oxidation can occur during Fe(II) oxidation by O2 and H2O2 due to the generation of reactive oxygen species (ROS). However, the mechanisms and effects of organic ligands on the co-oxidation of Sb(III) and Fe(II) require further investigation. This study provides detailed insights into the co-oxidation of Sb(III) and Fe(II) by O2 and H2O2, highlighting the influence of pH, anions, and organic ligands on the oxidation processes. The results contribute to a better understanding of the geochemical cycling and fate of Sb in subsurface environments and have implications for the in-situ remediation of Sb(III)-contaminated sites using Fenton reactions.

Summary: Mining, smelting, and tailing deposition activities can cause metalloid contamination in soils, posing a threat to ecosystems and human health. Microbial indicators play a crucial role in assessing soil ecological risks due to their sensitivity to environmental factors. This study focused on Xikuangshan, the largest active antimony mine in the world, and investigated soil properties, metalloid contents, and microbial characteristics. The results showed that the soils were mainly polluted by antimony, followed by cadmium and arsenic. Microbial characteristics varied among different sampling points in the mining area. The findings provide a theoretical basis for ecological risk assessment of contaminated soils.
