Summary: The coexistence of microplastics (MPs) and arsenic (As) in terrestrial ecosystems poses challenges to soil pollution control and environmental risk assessments. This study investigated the interactions between As, polystyrene MPs, and goethite in porous media, and evaluated their individual and combined toxicities on wheat germination. The results showed that the presence of MPs reduced As accumulation in wheat but inhibits wheat germination and promotes As migration within the plant body. The addition of goethite mitigated the toxicities of As and MPs, primarily through adsorption and immobilization. This study contributes to understanding the combined toxicity of MPs and As in crops and provides potential strategies for managing combined pollution.

Summary: Globally, heavy metal pollution of soil has remained a problem for food security and human health. This study characterized the toxicity symptoms of different concentrations of nickel (Ni) on pepper seedlings. The results showed that excess Ni reduced growth and biomass production, affected gas exchange elements and pigment molecules, and disrupted photosystem function. Higher Ni concentrations increased antioxidant enzyme activity and metabolites, but decreased nitrogen, potassium, and phosphorus levels. The uptake of Ni was higher in roots than shoots. Ni concentrations equal to or greater than 30 mg L-1 had a detrimental impact on pepper seedlings.

Summary: The attenuation of soil organic carbon and the destruction of soil microbial structure are common manifestations of grassland degradation. The addition of exogenous organic carbon and microorganisms may be an effective way to quickly restore degraded grassland, and the combination of biochar and effective microorganisms shows a synergistic effect in the restoration process.

Summary: Little attention has been paid to the effects of long-term application of crop straw and its biochar on soil phosphorus (P) transformation and carbon (C) fractions. This study investigated the influence of these amendments on soil C structure, P fractions, and their interaction with microorganisms. The findings reveal changes in soil P and C response under long-term crop straw and its biochar amendment and highlight the importance of biochar and straw return in future agriculture management.

Summary: The article discusses new strategies for remediating soils contaminated with organic and inorganic pollutants. The study focuses on investigating the combined effects of plant-microorganism-functional materials to enhance the reduction of soil contamination with toxic chemicals. The article highlights the importance of functional materials as a habitat for microorganisms, the role of microorganisms in partial biodegradation and plant growth stimulation, and the synthesis of root exudates by plants to facilitate microorganism activities. The cooperation of these three factors produces a synergistic effect that is more effective than individual approaches, such as phytoremediation or the use of microorganisms or functional materials alone. The article provides key examples of the synergistic effects observed in this study.

Summary: Excessive accumulation of Zn2+ or Ni2+ can cause developmental toxicity to zebrafish embryos and larvae, resulting in malformations and decreased body length and heartbeat rates. The interaction between Zn2+ and Ni2+ was found to be antagonistic, with individual exposure showing higher toxicity compared to combined exposure.

Summary: The impact of clay mineralogy on engineering properties, such as strength and stiffness, of road materials is investigated in this study. It is found that kaolinite is more effective than montmorillonite in reducing clay plasticity, and samples with high kaolinite content exhibit higher strength indicators. Additionally, kaolinitic soil samples have a larger constrained modulus than other samples.

Summary: This article provides an overview of the impact of certain soil biological-chemical properties on the bioavailability, mobility, and toxicity of vanadium. Although some aspects are well documented, there are points that need to be analyzed and described in greater detail. An important aspect that requires further investigation is the effect of vanadium on microorganisms and the soil processes they carry out.
