Summary: This study investigated the influence of long-term conventional tillage on the water-physical, chemical properties, and composition of chernozems. The results showed that tillage deteriorated the water-physical properties of the soil and affected the organic matter composition. The study also found that long-term plowing decreased aliphatic structures and increased aromatic structures in soils. To improve soil fertility and carbon sequestration potential, it is important to implement conservation tillage practices and prevent degradation processes.

Summary: This review compares CNTs and asbestos fibers in terms of their structural characteristics, bio-persistence, surface to volume ratio, and ability to adsorb toxins/pollutants. The study also examines the mechanisms underlying the toxicity caused by certain types of CNTs and asbestos fibers, using altered gene expression data. The results suggest that certain types of CNTs do indeed mimic asbestos fibers in terms of associated toxicity.

Summary: In this study, the effects of two types of multiwall carbon nanotubes (MWCNTs) on the kidneys and aging were compared. It was found that pristine MWCNTs could induce inflammation, apoptosis, insufficient autophagy, and premature kidney aging, with decreased Klotho levels and increased levels of DKK-1, FGF-23, and sclerostin in the serum. This study suggests that using MWCNTs in the industrial field may have toxic effects on the kidneys, and the dispersibility of the nanotubes can affect their toxicity.

Summary: This study compares the oxidation differences of sulfamethoxazole (SMX) by carbon nanotube (CNT)/peroxymonosulfate (PMS), nanodiamond (ND)/PMS, and PMS direct oxidation systems. The results showed that the reaction rate constant of the CNT/PMS system is significantly higher than the ND/PMS and PMS direct oxidation systems. Product analysis revealed differences in the oxidation mechanism and products among the different oxidation systems. Therefore, the choice of carbon catalyst plays a crucial role in the degradation and toxicity of organic pollutants in wastewater treatment.

Summary: This study investigated the detoxification mechanisms of red clover seedlings exposed to silver ions (Ag+) and found that the growth and physiological metabolism of the plants were disturbed. The research revealed that red clover seedlings initially transformed and immobilized Ag+ in the culture medium, and then transported and fixed them inside the cells, mainly in the form of unreduced Ag+ bound to biological molecules. Additionally, some Ag+ was reduced and formed crystalline silver nanoparticles. The results of this study provide valuable insights into the defense and tolerance mechanisms of red clover to Ag+ and the existing forms of Ag+ in vivo and in vitro.

Summary: Laser scanning confocal microscopy (LSCM) observations showed that polystyrene (PS) nanoplastics (25 nm) can be transferred to Daphnia magna's eggs and embryos through the brood chamber and ovary. In vivo and in vitro experiments confirmed the two pathways for maternal transfer: pathway I through the brood chamber and pathway II through the gut-ovary-oocyte transfer. The contribution from pathway I was much higher (88%) than pathway II (12%).

Summary: Positively charged nanoplastics induce stronger growth inhibition and gut damage in Chironomus kiinensis larvae compared to negatively charged nanoplastics. This is because the positively charged nanoplastics accumulate more readily in the gut, causing more severe oxidative stress, epithelial damage, and inflammatory responses. The positively charged nanoplastics also have a lower agglomeration rate, leading to increased interaction with gut cell membranes and microbiota. Furthermore, exposure to positively charged nanoplastics results in lower alpha diversity and relative abundance of key gut microbiota, exacerbating gut and growth damage.

Summary: Tl isotopic compositions were used for the first time to explore the transfer and pathway of Tl in paddy soil system. The results showed considerable variations in Tl isotopes, which were likely caused by interconversion between Tl(I) and Tl(III) under different redox conditions. Industrial waste was found to be the predominant source of Tl contamination in the studied soil. These findings suggest that Tl isotopes can be used as an efficient tracer to fingerprint Tl pathway in complicated scenarios, with significant prospects in diverse environmental applications.
