This study addresses the urgent need for cost-effective and sustainable remediation methods by evaluating the efficacy of green-synthesized hydroxyapatite (GHAP) in immobilizing Cd in paddy soils. The investigation focused on the effects of applying GHAP, commercial hydroxyapatite (CHAP), and pure hydroxyapatite (CK) on soil physicochemical properties, as well as Cd mobility and transfer within the soil-rice system. Our results demonstrate that GHAP significantly enhanced Cd adsorption and reduced bioavailable Cd content by up to 48.47 %, with the most effective results observed at a 1 % amendment rate. Additionally, GHAP application elevated soil pH and available phosphorus, contributing to better soil structure, fertility, and rice growth. Correlation and principal component analyses revealed that the GHAP dosage was a key factor in modifying soil properties and influencing Cd speciation and mobility. These findings suggest that a 1 % GHAP dosage achieves an optimal balance between improving soil quality and effectively passivating Cd, making GHAP a promising amendment for remediating Cd-contaminated soils.</div></div>","PeriodicalId":303,"journal":{"name":"Ecotoxicology and Environmental Safety","volume":"297 ","pages":"Article 118267"},"PeriodicalIF":6.2,"publicationDate":"2025-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143898663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the effects of PS exposure, particularly in diabetes, have not been adequately explored. Most studies focus on high-concentration, long-term exposure, which does not reflect typical human exposure levels. This study investigates the effects of short-term PS exposure on diabetic SD rats, using histological, apoptotic, and omics techniques, including metabolomics, lipidomics, and 16S rDNA sequencing. Our results show that short-term PS exposure exacerbates lung and intestinal damage in diabetic rats, with significant alterations in the gut microbiome. We also observed correlations between differential metabolites and microbiota changes.

In this study, we aimed to investigate the intensity of acute inflammatory responses, as well as the activation levels of complement C5 and its related products, C5aR1 and C5b-9, following exposure to different types of PM. Acute inflammatory responses and complement activation were assessed in mice intratracheally administered four types of PM: titanium dioxide (TiO₂), diesel exhaust particles (DEP), Asian sand dust (ASD), and ambient PM with an aerodynamic diameter ≤ 2.5 μm (PM2.5). Complement system and inflammatory markers were evaluated by analyzing increased C5 protein levels, C5b-9 deposition, and C5aR1 expression. Additionally, dark-field microscopy and Raman microscopy were used to detect PM components adjacent to infiltrating neutrophils, and elemental composition was quantified using ICP-MS and EDXRF. ASD, DEP, and PM2.5 exposure significantly increased C5b-9 deposition in lung tissues. All PM-exposed groups exhibited substantial upregulation of C5aR1 expression, primarily in neutrophils. Raman spectroscopic analysis revealed Si, K, Mg, Al, and Fe adjacent to infiltrating neutrophils in ASD-exposed lungs. Furthermore, elemental analysis identified Si, Mg, Al, and K as the most potent contributors to complement activation and inflammatory responses. Of the four types of PM, ASD induced the most severe acute inflammatory response and complement system activation. Therefore, ASD-induced complement system activation, driven at least partly by its mineral components, may play a critical role in neutrophil activation and acute pulmonary inflammation.

First, PS-MPs were characterized using FTIR spectroscopy, TEM, and fluorescence microscopy. To assess reproductive toxicity, female mice were exposed to polystyrene microplastics (PS-MPs) at a dose of 30 mg/kg with an average particle size of 1 μm for 35 days. As a result, PS-MPs accumulated in the ovaries, leading to increased follicular atresia and apoptosis of granulosa cells. TEM revealed abnormal mitochondrial morphology in granulosa cells. Post-superovulation treatment, significant differences were noted in the number of ovulated metaphase II (MII) oocytes, spindle chromosome integrity, mitochondrial patterns, and ROS levels compared to controls. Mating with PS-MPs-exposed females led to fewer offspring. The in vitro follicle culture system proved promising for assessing PS-MPs reproductive toxicity. Immunohistochemistry showed increased Cleaved Caspase 3 and decreased Bcl2 levels in PS-MPs-treated groups, indicating apoptosis in granulosa cells.
