This study examines how several properties of soil colloids, including pH, phosphorus content, clay minerals, and iron oxyhydroxides, influence the interaction with zinc oxide nanoparticles (ZnO-nps). For the experimental setup, four different soils were selected from the temperate climate of central Europe, in Slovakia, exhibiting pH values ranging from 4.6 to 8.0. Two concentrations of ZnO-nps suspended in water, 20 and 200 mg Zn∙L⁻¹ were applied to the colloidal suspensions extracted from the soils and shaken for 24 h. Then the soil colloids were separated into three fractions, 100–1000 nm in size, 1–100 nm in size, and dissolved. Concentrations of Al, Si, Fe, Mn, P, and Zn were measured in these fractions, providing a comprehensive understanding of ZnO-NP distribution and interaction with soil colloids. The study reveals that soil pH significantly affects the distribution of Zn from ZnO-nps across different size fractions. However, the concentration of Fe, Al, and Si had an even greater impact on the concentration of dissolved Zn. Additionally, behavior of Zn following ZnO-NP application is associated with soil P content, where P may stabilize the ZnO-nps. These findings enhance the knowledge of nanoparticle behavior in various soil matrices and contribute to developing more stable, efficient, and easily useable nanoparticle-based applications in environmental science and agriculture.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"370 ","pages":"Article 144001"},"PeriodicalIF":8.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142873151","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}

Moreover, BPs from mobile sources like vehicles contribute significantly to overall human exposure, further complicating exposure assessments. The review also delves into the transformation of BPs within indoor environments, emphasizing the diverse roles of physical, chemical, and biological processes in generating various transformation products (TPs). These TPs can exhibit heightened toxicity compared to their parent compounds, necessitating deeper investigations into their environmental fate and potential health implications. Critical examination of biomonitoring techniques for BPs and their metabolites underscores the importance of non-invasive sampling methods, offering ethical advantages and practicality in assessing human exposure levels.

Insects have been shown to present various responses to multi-stress conditions (i.e., increase in temperature and exposure to contaminants). However, there is a knowledge gap on how temperature can modulate the hormetic effects in individuals sublethally exposed to chemical stressors. Here, we investigated how temperature (15, 20, 25, and 28 °C) modulates the effects of lethal and sublethal exposure to insecticides (imidacloprid) on the longevity, fecundity, and oxidative stress of a pest insect, the aphid <em>Mysus persicae</em>. Our results showed additive and interactive effects of temperature and insecticide on the stimulatory and oxidative responses of the insect pest. Overall, imidacloprid was 2.4-fold less toxic at 15 °C (3.547 μg/ml) than at 20 °C (1.482 μg/ml) and 24.6 to 19.8-fold less toxic than at 25 °C (0.144 μg/ml) and 28 °C (0.179 μg/ml) respectively. Furthermore, although the exposure of female aphids to most sublethal concentrations resulted in a decrease in their longevity and fecundity compared to the control, some of the sublethal concentrations produced positive effects in these parameters for the exposed individuals. The magnitude of induced sublethal effects varied between temperatures and occurred in similar ranges of low concentrations at temperatures 15 °C and 20 °C, and at temperatures 25 °C and 28 °C. Additionally, imidacloprid low concentrations induced a temperature-dependent production of reactive oxygen species in exposed insects at 12 and 24 h after exposure indicating oxidative stress. Our study supplies valuable data on how temperature modulates pesticide-mediated hormesis that can alter ecological interactions and functions within agroecosystems with potential implications in pest management.</div></div>","PeriodicalId":276,"journal":{"name":"Chemosphere","volume":"370 ","pages":"Article 143920"},"PeriodicalIF":8.1,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142808813","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, key genes involved in the four metabolic steps (hydrolysis, acidogenesis, acetogenesis, and methanogenesis) remain largely unexplored. This study investigated the abundance and distribution of key functional genes in full-scale anaerobic digesters processing food waste (FWDs) and municipal wastewater (MWDs) through 16S rRNA gene and shotgun metagenomic analysis. Our results revealed that FWDs exhibited a higher abundance of key genes in the metabolic steps, despite having significantly lower microbial diversity compared to MWDs. Pathways and genes associated with syntrophic oxidation of acetate (SAO) and butyrate (SBO) were more present in FWDs. SAO potentially used both the conventional reversed Wood-Ljungdahl pathway and its integration with the glycine cleavage system in FWDs, which complements pathways for acetate oxidation under ammonia stress conditions. Similarly, genes associated with SBO (<em>atoB</em> and <em>croR</em>) were notably more prevalent in FWDs compared to MWDs with an 8.4-fold and 108-fold increase, respectively, indicating the adaptation of SBO bacteria to convert butyrate into acetate. The higher abundance of key genes in FWDs was driven by microbes adapting to the feedstock compositions with higher levels of substrate content, volatile fatty acids, and ammonia. This study quantified the genes central to AD metabolism and uncovered the contributions of microbial diversity, gene abundance, syntrophy, and feedstock characteristics to the functionality of AD processes.
