Incidental nanoparticle characterisation in industrial settings to support risk...
Moreno-Martín, V; López, M; Bou, D; Fraga, S; Teixeira, JP; López-Lilao, A; Sanfélix, V; Monfort, E; Viana, MResearch on nanoparticle (NP) release and potential exposure can be assessed through experimental field campaigns, laboratory simulations, and prediction models. However, risk assessment models are typically designed for manufactured NP (MNP) and have not been adapted for incidental NP (INP) properties. A notable research gap is identifying NP sources and their chemical, physical, and toxicological properties, ...
Potential human exposure and risks of incidental nanoparticles released during ...
Moreno-Martín, V; López, M; Roldan, C; Bou, D; Fraga, S; Teixeira, JP; López-Lilao, A; Sanfélix, V; Moliner, R; Monfort, E; Viana, MRotary dry cutting and rectifying of ceramic tiles are sources of fine particulate matter (PM2.5) and nanoparticles (NPs). These activities are typically carried out inside industrial facilities during the manufacturing process, as well as outdoors and in residential indoor spaces during the installation phase, where mitigation measures are seldom implemented. This work aimed to understand the particle formatio...
Unveiling the Toxicity of Fine and Nano-Sized Airborne Particles Generated from...
Bessa, MJ; Brandão, F; Fokkens, PHB; Leseman, DLAC; Boere, AJF; Cassee, FR; Salmatonidis, A; Viana, M; Monfort, E; Fraga, S; Teixeira, JPHigh-energy industrial processes have been associated with particle release into workplace air that can adversely affect workers' health. The present study assessed the toxicity of incidental fine (PGFP) and nanoparticles (PGNP) emitted from atmospheric plasma (APS) and high-velocity oxy-fuel (HVOF) thermal spraying. Lactate dehydrogenase (LDH) release, 2-(4-nitrophenyl)-2H-5-tetrazolio]-1,3-benzene disulfonate...
Characterizing the Chemical Profile of Incidental Ultrafine Particles for Toxic...
Viana, M; Salmatonidis, A; Bezantakos, S; Ribalta, C; Moreno, N; Córdoba, P; Cassee, F R; Boere, J; Fraga, S; Teixeira, J P; Bessa, M J; Monfort, EIncidental ultrafine particles (UFPs) constitute a key pollutant in industrial workplaces. However, characterizing their chemical properties for exposure and toxicity assessments still remains a challenge. In this work, the performance of an aerosol concentrator (Versatile Aerosol Concentration Enrichment System, VACES) was assessed to simultaneously sample UFPs on filter substrates (for chemical analysis) and ...
In Vitro Toxicity of Industrially Relevant Engineered Nanoparticles in Human Al...
Bessa, MJ; Brandão, F; Fokkens, PHB; Leseman, DLAC; Boere, AJF; Cassee, FR; Salmatonidis, A; Viana, M; Vulpoi, A; Simon, S; Monfort, E; Teixeira, JPDiverse industries have already incorporated within their production processes engineered nanoparticles (ENP), increasing the potential risk of worker inhalation exposure. In vitro models have been widely used to investigate ENP toxicity. Air–liquid interface (ALI) cell cultures have been emerging as a valuable alternative to submerged cultures as they are more representative of the inhalation exposure to airbo...
Toxicity assessment of industrial engineered and airborne process-generated nan...
Bessa, MJ; Brandão, F; Fokkens, P; Cassee, FR; Salmatonidis, A; Viana, M; Vulpoi, A; Simon, S; Monfort, E; Teixeira, JP; Fraga, SThe advanced ceramic technology has been pointed out as a potentially relevant case of occupational exposure to nanoparticles (NP). Not only when nanoscale powders are being used for production, but also in the high-temperature processing of ceramic materials there is also a high potential for NP release into the workplace environment. In vitro toxicity of engineered NP (ENP) [antimony tin oxide (Sb2O3•SnO2; AT...

Nanoparticle exposure and hazard in the ceramic industry: an overview of potent...
Bessa, MJ; Brandão, F; Viana, M; Gomes, JF; Monfort, E; Cassee, FR; Fraga, S; Teixeira, JPThe ceramic industry is an industrial sector of great impact in the global economy that has been benefiting from advances in materials and processing technologies. Ceramic manufacturing has a strong potential for airborne particle formation and emission, namely of ultrafine particles (UFP) and nanoparticles (NP), meaning that workers of those industries are at risk of potential exposure to these particles. At p...
