Due to the growing use of nanoparticles in industrial processes, the number of workers potentially exposed is increasing while the toxicological effects of these compounds have not been fully characterized yet. Because inhalation represents…

Due to their physical and chemical properties, carbon nanotubes (CNTs) are among the most promising nanomaterials in terms of industrial use. In order to assess their toxicological properties, inhalation experiments performed on laboratory…

Handling CNTs powders is a plausible scenario over the entire life-cycle for CNTs. However limited exposure data exist today. In this context, there is no doubt that dustiness data can be of great interest for e.g, control banding or exposure modeling…

The “dustiness” of nanomaterial powders has been tested using several different quantification methods that all involve the application of a given mechanical energy level to a particular amount of powder, whereby nano-objects and their agglomerates…

Because of their ability to measure short-term fluctuations, photometers are increasingly used for real-time aerosol characterization in workplace atmospheres. Despite the need for a custom calibration factor to obtain more accurate mass…

In the context of a pre-normative research project under the mandate 461 between the European Commission and CEN, the vortex shaker method was developed and evaluated in the dustiness investigation of 25 bulk nanomaterials powders that include…

Relevancy of dustiness methods are increasingly recognized in a preliminary exposure evaluation of workers handling nanomaterials in powder form. Until now, the methods recommended in the current European standards mainly indicate to determine…

Nanomaterials are full of promise in fields as varied as healthcare, agrifood, energy, materials, and transport. Research for developing them is therefore very active and the accompanying economic stakes are considerable. The data relating to…

The project focuses on the issues of preventing occupational risks related to nanoscale particles, be they of unintentional or of manufactured origin. On the basis of the various recommendations established in France and internationally…
