Summary: Evaluating the variation in heavy metal concentrations caused by human activities in contaminated areas is important. Different indices and reference elements are used to assess heavy metal pollution in soil, but they cannot evaluate the pollution caused by human activities. This study compared the concentrations of heavy metals in soil profiles in a contaminated area and a background area in China, finding higher concentrations in the contaminated area. The study also used prediction models to depict the increase in heavy metal concentrations in the topsoil due to anthropogenic activities.

Summary: The continuous use of pesticides has harmful effects on the ecosystem and accumulates in the food chain. Salicylic acid plays a role in regulating the toxicity of pesticides, but its significance is often overlooked. In the presence of salicylic acid, genes and proteins related to detoxification processes are upregulated, leading to a defense network against pesticide stress. This review aims to understand how salicylic acid is involved in pesticide detoxification to regulate stress in plants and explore its wider applications.

Summary: Synchronized indoor and outdoor sampling campaigns were conducted in Mexico City during the dry cold season to measure PM10 mass and elemental concentrations, identify particle origins and their penetration into indoor environments, and assess health risks. X-ray Fluorescence was used to measure concentrations of 18 elements, and Scanning Electron Microscopy was used to analyze selected samples. Outdoor mass concentrations were higher, while elemental concentrations were similar indoors and outdoors. Enrichment factors revealed the presence of geogenic elements, and Cluster Analysis identified common sources of elements and the penetration of outdoor particles indoors. Indoor emissions were distinguishable. Health risks associated with exposure to Mn, Fe, Ni, Cu, Zn, and Pb particles were low, with only Cr posing an ingestion risk. Hazard Quotients for outdoor Mn and Ni were higher than indoors.

Summary: Our previous studies showed that viridicatol from the deep-sea-derived fungus Penicillium griseofulvum can regulate mast cell stabilization and relieve food allergy. To understand the molecular mechanisms, transcriptomes of viridicatol-treated RBL-2H3 cells were analyzed. Differentially expressed genes and enrichment analysis indicated that viridicatol played a significant role in mast cell stabilization by affecting MAPK and JAK-STAT signaling pathways.

Summary: This study examined the effects of particulate matter (PM) on endoplasmic reticulum (ER) stress in human bronchial epithelial (HBE) cells and identified potential molecular mechanisms. The results showed that PM exposure induced elevations in the ER stress hallmarks GRP78 and IRE1α in the HBE cells. Inhibition of ER stress alleviated the PM-induced effects and possibly regulated PM-induced inflammation through autophagy and NF-κB signaling pathways.

Summary: In this study, an effective adsorbent, succinic acid functionalized Fe3O4@AMPA nanocomposite, was synthesized and used for the efficient removal of Cd(II) ions from aqueous media. Characterization of the Fe3O4@AMPA@SA nanocomposite was done using zeta potential, BET, TEM, TGA, and FTIR spectra. The batch experiment method was used to investigate the influence of pH value, initial Cd(II) concentration, adsorbent dosage, temperature, and contact time on the adsorption process. The results showed that the Fe3O4@AMPA@SA nanocomposite exhibited a maximum monolayer adsorption capacity of 265 mg g(-1) for Cd(II) ions.

Summary: The indoor simulation remediation experiment investigated the effects of different remediation agents, dosage, water-soil ratio, and remediation time on the reduction and stabilization efficiency of chromium-contaminated soil in semi-arid areas. The results showed that FeSO4 was the most effective reduction agent, and the optimal remediation conditions included a specific combination of dosage, biochar, water-soil ratio, and remediation time. After treatment, the leaching concentrations and content of Cr(VI) in the soil were significantly reduced and met the relevant standards.

Summary: Cadmium is a widely used environmental pollutant that can cause various health issues, particularly related to reproductive health. This review focuses on the impact of cadmium exposure on female reproductive health, including during and after pregnancy. Cadmium exposure has been found to disrupt steroidogenesis, delay puberty, affect reproductive hormones, disturb menstrual cycles, increase the risk of premature births, and reduce birth weights in females. Additionally, prenatal exposure to cadmium has been shown to have differential effects on offspring, with more negative impacts on female offspring. Furthermore, lactation with cadmium-contaminated milk can lead to disparities in brain physiology, reflex changes, and physical immaturity in nursing babies. These findings highlight the importance of conducting further studies on the consequences of cadmium exposure on reproductive health.

Summary: Target analysis combined with traceability analysis was used to identify the type of PFASs present in surface water and sediment around fluorine industry parks (FIPs) in China. Risk characterisation ratio was employed to evaluate the risk posed by these PFASs to the surrounding river. The study found the presence of 10 and 15 PFASs in surface water and sediment, with concentrations reaching up to 32,674.0 ng/L and 17.84 ng/g, respectively. Short-chain PFASs, particularly perfluoropentanoic acid, were predominant. Source analysis suggested that PFASs in surface water originated from precursor degradation and atmospheric deposition, while the fluorine rubber industry was the main source for PFASs in sediment, especially short-chain compounds. A risk characterisation ratio analysis identified several compounds, including perfluorododecanoic acid, perfluorobutane sulfonate, perfluoroheptanoic acid, perfluoropentanoic acid, and perfluorohexanoic acid, as having relatively high risks.

Summary: Effective passivation of heavy metals in sludge is crucial for its land use. GxK900, a modified potassium feldspar with lower crystallinity, higher specific surface area, and cationic exchange capacity, was chosen to passivate heavy metals in the sludge. The optimal passivation conditions were 30% addition and a 10-day passivation period. The passivated sludge extract had no adverse effects on ryegrass germination and promoted radicle growth. The pot experiment showed that adding 10% passivated sludge enhanced ryegrass growth without significantly affecting the contents of Cu, Cr, Zn, and Pb in the roots and above-ground parts. The transfer factors of the four metals were all less than 1. The use of passivated sludge as a growing medium for landscaping plants provides a theoretical basis for sludge land use and a resource outlet for potassium feldspar minerals.

Summary: A novel strategy for reclamation and reuse of phosphate from aqueous solution was developed using Mg-enriched biochar prepared from anaerobically digested sludge. The adsorption of phosphate on ADBC-600 could be well described by the pseudo-second-order model and Langmuir model, indicating that the adsorption was mainly dominated by chemisorption process. The spent biochar was also re-utilized as an efficient phosphate fertilizer for improving crop seed germination and growth.
