The goal of this work was to identify a set of characterization tools/procedures to support the operationalization of the first three safety steps to multi-component nanomaterials (MCNMs), applying the findings to a SiO2<small><sub></sub></small> core-ZnO shell MCNM. The safety of this MCNM, used as additive to a silicate/calcium hydroxide mortar to improve air quality through photocatalytic NOₓ removal, was investigated from different perspectives along its value chain. Existing and newly generated data on its hazard profile were collected, workers’ exposure during synthesis was assessed, and potential exposure to hazardous substances during its final application phase was investigated. Concerning step 1, physico-chemical properties, hazard classification and cytotoxicity assays were considered. Afterwards, a three-tiered established methodology for evaluating occupational exposure assessment was performed for step 2. Lastly, for step 3, the release of inorganic substances from the MCNM-based mortars in the final application phase was investigated. Safety assessment according to the SSbD framework was done by selecting tools and procedures suitable for application at an early innovation stage, resulting in a preliminary hazard assessment of the MCNM and a suggestion for redesigning a step in the process.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142487245","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}

Through extensive field studies, we examined the distribution of Gram-positive and Gram-negative bacteria across different agricultural activities, revealing distinct patterns linked to these practices. Our results show that sowing and fertilization promote the proliferation of Gram-positive bacteria, while weeding favors Gram-negative species. Specifically, during sowing, Gram-positive bacteria made up 75% of the bacterial population, whereas during weeding, Gram-negative bacteria constituted 75%. Irrigation and harvesting displayed balanced microbial compositions, with each bacterial group representing 50% of the population. Additionally, we measured particulate matter concentrations during various agricultural tasks, finding elevated levels of PM1 (48 µg/m3 during weeding), PM2.5 (65 µg/m3 during weeding), PM10 (86 µg/m3 during weeding), CO2 (1027 ppm during irrigation), and formaldehyde (0.013 ppm during harvesting). These results highlight the need for targeted mitigation strategies to protect air quality and human health in agricultural settings. Our analysis of bacterial aerosols revealed significant variations in bioaerosol concentrations, ranging from 30 CFU/ml during weeding to 80 CFU/ml during fertilization. This underscores the importance of implementing effective risk management measures to address potential health impacts. Furthermore, we identified both pathogenic and beneficial bacterial species within agricultural ecosystems, stressing the importance of preventive measures against contamination while leveraging beneficial bacteria to improve crop productivity and soil fertility. Overall, this study enhances our understanding of the interplay between agricultural practices, microbial dynamics, and human health, informing more sustainable agricultural management practices.</p></div>","PeriodicalId":808,"journal":{"name":"Water, Air, & Soil Pollution","volume":null,"pages":null},"PeriodicalIF":3.8,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142518511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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 distribution of these nanoparticles (NPs) in the environmental system represents an emergency problem for understanding the generation of reactive oxygen species (ROS) and their unpredictable effect on micro and macro fauna/flora due to their chemical form. This study describes strategies to evaluate the dispersion of IONPs in environmental media under controlled conditions of pH (5 – 9), hardness (0 – 400 mg CaCO3 L-1), temperature (10 – 30 °C), and exposure time (0 – 48 h) in aquatic systems. For this purpose, iron-based nanoparticles (hematite, goethite, and magnetite) were synthesised and characterised using chemical and morphological analytical techniques. Subsequently, the effect of environmental parameters on NPs dispersion was investigated by developing a model using a central composite rotatable design (CCRD) with total Fe as the dependent variable. The IONPs were synthesised with a size minor than 100 nm for the three nanoparticles. It was observed that the nano-hematites and magnetites had spherical morphology while goethite appeared as nanorods. The resulting models, integrating linear, quadratic, and combined effects, exhibit high predictive capacities – 76.4%, 93.6%, and an impressive 99.9% for nano-hematite, goethite, and magnetite, respectively. This research contributes to understanding nanoparticle behaviour in natural settings, providing essential insights to assess and potentially mitigate the adverse consequences of IONPs contamination in aquatic environments.","PeriodicalId":73,"journal":{"name":"Environmental Science: Nano","volume":null,"pages":null},"PeriodicalIF":8.131,"publicationDate":"2024-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142487697","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}

Further, the nutritional quality of lettuce leaves was generally improved as evidenced by the increased soluble protein and soluble sugar as well as the decreased nitrate. The decrease of superoxide dismutase activity and accumulation of MDA suggested oxidative stress induced by PS NPs and PS MPs. Metabolomics analysis showed that foliar exposure to PS NPs disturbed the energy metabolism, glutathione metabolism, and ABC transporter, whereas PS MPs perturbed the lipid metabolism and cutin, suberin and wax biosynthesis in lettuce leaves. The different metabolic responses between PS NP and PS MP treatments highlighted the importance of particle size in investigating the phytotoxicity of airborne plastic particles.

However, the introduction of g-CN improved overall plant health, reducing Cd toxicity by 35% at an optimal dosage of 150 mg/L. The g-CN's effectiveness is attributed to its structural and chemical properties, as revealed by comprehensive characterization.

Initially, the preparation of MXene nanosheets, pivotal to membrane fabrication, is detailed. Subsequently, the fabrication methods of MBMs are presented, emphasizing filtration, coating assembly, and other fabrication techniques. Furthermore, we emphasize the modification strategies employed to enhance the performance of MBMs. These encompass the regulation of MXene nanosheets in terms of lateral size, terminal functional groups, and in-plane pores. Furthermore, adjustments are made to the membrane assembly processes, focusing on controlling interlayer spacing. This includes methods such as self-crosslinking, insertion, and the incorporation of hybrid functional layers. Additionally, surface modifications encompass the regulation of surface charge, surface wettability, and management of surface defects. Next, we delineate the key membrane applications, encompassing separation mechanisms and their promising utility.
