This work presents a blueprint or set of guidelines for the planning and development of sustainable national centers dealing with the safety of nanomaterials and nanotechnologies toward public health and environment. The blueprint was developed following a methodological approach of EU-wide online survey and workshop with several stakeholders. The purpose was to identify the key elements and challenges in the development and sustainability of a national nanosafety center. The responses were rece...

Measured data are generally preferred to modelled estimates of exposure. Grouping and read-across is already widely used and accepted approach in toxicology, but an appropriate approach and guidance on how to use existing exposure measurement data on one substance and work situation for another substance and/or work situation is currently not available. This study presents a framework for an extensive read-across of existing worker inhalable exposure measurement data. This framework enables the ...

Dustiness is not an intrinsic physically defined property of a powder, but the tendency of particles to become airborne in response to mechanical and/or aerodynamic stimuli. The present study considers a set of 10 physical properties to which the powder dustiness can be attributed. Through a preliminary investigation of a standardized continuous drop test scenario, we present first set of results on the varying degrees or weights of influence of these properties on the aerosolization tendency of...

Characterization of the exposition to nanoparticles and nano-objects at workplaces is a huge technical challenge. Workplace exposure during short durations is particularly difficult to detect due to the low performances of the samplers. This article proposes a solution allowing for characterizing emissions at workplaces and presents the results obtained from a nanomaterials exposure measurement campaign performed on six different process lines (PLs) distributed all over Europe. By using our Shor...

The shredding of waste of electrical and electronic equipment (WEEE) and other products, incorporated with nanomaterials, can lead to a substantial release of nanomaterials. Considering the uncertainty, complexity, and scarcity of experimental data on release, we present the development of a Bayesian belief network (BBN) model. This baseline model aims to give a first prediction of the release of nanomaterials (excluding nanofibers) during their mechanical shredding. With a focus on the descript...

For sustainable development of nanotechnology, nanomaterials should follow a safer-by-design approach so that the associated exposure and hazard risks throughout their entire life cycle can be minimized without compromising their functioning efficiency. In this context, we present organic–inorganic hybrid nanostructures composed of titanium dioxide (TiO2) nanoparticles grafted onto cellulose nanocrystals (CNC) using a sol–gel process. After grafting optimization, we show that the overall efficie...

The present article presents an experimental protocol to investigate particle aerosolization of a product under abrasion and under environmental weathering, which is a fundamental element to the approach of nanosafety-by-design of nanostructured products for their durable development. This approach is basically a preemptive one in which the focus is put on minimizing the emission of engineered nanomaterials' aerosols during the usage phase of the product's life cycle. This can be attained by alt...

This article focuses on the development of an analytical model that simulates the particle aerosols emission from the traditional products under the effect of their mechanical abrasion at low abrasion speeds. An interdisciplinary approach is adopted. The information on the model development and its results are detailed here with all the assumptions which were taken during development. The model results suggest that the product formulation is an important aspect during particle aerosols emission ...

In this work, the particle aerosols emissions during the abrasion of three products – brick, wood and stainless steel – are measured. Owing to different material removal mechanisms in these three products during their abrasions, different quantities and generation rates of aerosols are observed with the brick producing the highest number at a constant rate, followed by the wood at continuously decreasing rate and at last the stainless steel with a constant rate. As per our knowledge, there is no...

In the present work, we investigate the effect of weathering duration on a commercial photocatalytic nanocoating on the basis of its nanoparticle emission tendency into two media, air and water. It is found that increased weathering duration results in stepwise structural deterioration of the nanocoating, which in turn decreases the nanocoating life, changes the nanocoating removal mechanism, and increases the particle emission concentration. Emission of free TiO2 nanoparticles is found to be we...
