Integrated approaches to testing and assessment (IATAs) emerge as efficient tools to streamline the risk assessment of MNMs. This study formulates an Occupational Hazard IATA (OH IATA) to identify and quantify the hazard of involuntarily inhaled MNMs in workplaces. Following general IATA guidance, key toxicity events (KTEs) relevant to inhaled MNMs, such as deposition, accumulation, local or systemic inflammation, and genotoxicity, were identified and incorporated into decision nodes (DNs) within the OH IATA framework. The OH IATA is structured as a decision tree enabling tiered testing strategies, from in vitro to in vivo, to generate evidence addressing the DNs. Hazard profiles are categorized into bands labeled from A (no risk) to E (serious hazard), following ISO control banding principles and including new criteria focusing on key physicochemical descriptors like deposition and dissolution in synthetic biological fluids. The OH IATA was evaluated using industrial case studies such as few-layer graphene (FLG) and graphene oxide (GO), applying a hybrid data-gathering approach that combines next-generation and literature-based data. The results demonstrated that OH IATA successfully assigned hazard bands to the tested MNMs and supported the identification of appropriate control measures.

MXenes have gained significant attention, due to their potential in energy storage, biomedicine, and environmental remediation. However, the safe and sustainable implementation of these materials is hindered by critical gaps in safety, sustainability, and regulatory data. This study applies the OECD's Early4AdMa anticipatory risk governance tool to systematically identify potential risks and challenges associated with titanium carbide (Ti₃C₂) MXenes, the most extensively studied of the MXenes. We highlight critical uncertainties around human health and environmental impacts, stemming from discrepancies in acute toxicity studies, insufficient data on pulmonary exposure, genotoxicity, and long-term effects, and limited understanding of environmental fate and ecotoxicity. These knowledge gaps are sustained by the lack of harmonised guidance on sample preparation and dosimetry tailored to the unique morphology of MXenes. Moreover, life-cycle assessments demonstrate the high environmental cost of conventional synthesis methods, underlining the need for greener, energy-efficient alternatives and sustainable innovation approaches. In addition to addressing these knowledge gaps, a key follow-up action is the evaluation of the need to update regulatory guidance documents related to material characterization relevant for such 2D materials (e.g., lateral size, layers, and terminal groups) to ensure comprehensive risk assessment. The present study not only identifies actions to improve the safety and sustainability of Ti₃C₂ MXenes, but also provides a basis for the evaluation of other emerging materials.</div></div>","PeriodicalId":18786,"journal":{"name":"NanoImpact","volume":"40 ","pages":"Article 100588"},"PeriodicalIF":5.5,"publicationDate":"2025-09-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145092116","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

Additionally, the physiological ecology of three species was also investigated after 7 d of exposure to different PS bead sizes. The results showed that fresh weight and growth inhibition was unaffected by particle sizes, while root length, shoot mass and root mass inhibition was significantly higher in <em>C. sativus</em> than that in <em>P. vulgaris</em> and <em>S. bicolor</em> (mean 28.6, 5.5 and 2.8 in <em>C. sativus, P. vulgaris</em> and <em>S. bicolor</em>, respectively).

Fluorescence intensity values of PS beads accumulation in different tissues confirmed these results. Malondialdehyde levels in seedling leaves of <em>P. vulgaris</em> and <em>C. sativus</em> were elevated in PS treatment groups but unchanged in <em>S. bicolor</em>.

In conclusion, different PS bead sizes significantly affected the accumulation and distribution in all species, as well as the antioxidant response.

By combining proteomic and targeted approaches, we determined that red iron oxide (but not black iron oxide) induces perturbations in mitochondria, altering the mitochondrial transmembrane potential.

In this study, we investigated the behavior and cytotoxicity of PS-NPs in the presence of a nutritionally relevant, real food matrix (milk) under simulated three-phase gastrointestinal digestion. PS-NPs of three different sizes (30 nm, 100 nm, and 450 nm) were characterized before and after digestion using SEM, TEM, DLS, and XPS to monitor changes in aggregation and corona structure. Our findings demonstrated that milk proteins and digestive enzymes adsorbed onto the PS-NP surfaces, forming a complex protein corona. The aggregation behavior and composition of the protein corona were markedly influenced by particle size during the digestion process. Corona structures were detected on all particle sizes following digestion; however, extensive web-like agglomerates were uniquely observed in the 30 nm particles. While the presence of milk during digestion did not significantly alter the cytotoxicity of the 30 nm and 450 nm particles, it resulted in a marked reduction in cell viability for the 100 nm particles.

A crucial step in this process is to link release assessments based on material flow analysis (MFA) with the fate and transport models. This paper presents a novel model that couples a form-specific probabilistic material flow analysis (PMFA) release model with a highly spatiotemporally resolved fate and transport river model. The effects of tides and the experimentally derived dissolution rate are incorporated into the modeling to accurately reflect the realistic environmental conditions of the study area, a coastal river in southern Taiwan. The PMFA results show that the pristine form of ZnO nanoparticles released into surface waters accounts for 89 % of the total ZnO nanoparticles released to surface waters, due to the limited coverage of the wastewater treatment system. Dissolution was the predominant fate process for ZnO nanoparticles in the Yanshuei River, while heteroaggregation was less important. Free ZnO nanoparticles only occurred sporadically and were noticeable at the discharge points, with the highest mean steady-state concentration of 0.9 μg/L. Free Zn ion was the major ZnO nanoparticles-derived product species, with an average steady-state concentration that can accumulate downstream to 7 μg/L. A sensitivity analysis indicated the importance of dissolution at dissolution rates k_diss &gt; 3 d⁻¹, while heteroaggregation became important when k_diss ≤ 0.1 d⁻¹. The tides significantly affected the distributions of Zn species along the river. Within 2 months of simulation time, the high tide resulted in the accumulation of Zn species as much as 3 times higher at the river sections receiving large loads, while the low tide drained the plumes of Zn species.
