“…Similar findings were reported for other powder handling operations [14,15]. The measurement of the dustiness of nanopowders showed the generation of high concentrations of submicron particles, but not in the nano-regime [16,17].…”

“…Similar results were obtained by Tsai et al [ 53 ] for TiO 2 and ZnO metal oxide powders with slightly modified measurement devices (SMPS, APS, and MOUDI). Isbaseta & Biscans [ 70 ] investigated TiO 2 and SiO 2 in free drop conditions. Despite large deviations in the PSD determined by an ELPI, both powders show a release of nanoparticles of 10 mg·m -3 an40 mg·m -3 for TiO 2 .and SiO 2 , respectively, for the same initial sample mass.…”

Risk, associated with nanomaterial use, is determined by exposure and hazard potential of these materials. Both topics cannot be evaluated absolutely independently. Realistic dose concentrations should be tested based on stringent exposure assessments for the corresponding nanomaterial taking into account also the environmental and product matrix. This review focuses on current available information from peer reviewed publications related to airborne nanomaterial exposure. Two approaches to derive realistic exposure values are differentiated and independently presented; those based on workplace measurements and the others based on simulations in laboratories. An assessment of the current available workplace measurement data using a matrix, which is related to nanomaterials and work processes, shows, that data are available on the likelihood of release and possible exposure. Laboratory studies are seen as an important complementary source of information on particle release processes and hence for possible exposure. In both cases, whether workplace measurements or laboratories studies, the issue of background particles is a major problem. From this review, major areas for future activities and focal points are identified.

“…On the contrary, the dust liberation property of disperse particle systems depends on a multitude of variables and also on the method and intensity of stressing. During an investigation of TiO 2 and SiO 2 powders in free drop conditions, [41] demonstrated a release of nanoparticles of 10 mg/m 3 and 40 mg/m 3 for TiO 2 and SiO 2 , respectively. The SWCNT agitating principle of [42,43] in a centrifuge tube has also been used by [44] to characterize the amount, particle size distribution, and morphology from different nanostructured powders including TiO 2 and ZnO and carbon materials like SWCNT, MWCNT, and fullerenes.…”

This paper focuses on presenting the forefront of the interdisciplinary studies conceived towards the generation of the wear particles aerosol when materials are subjected to mechanical stresses. Various wear mechanisms and instrumentation involved during stress application and aerosolization of wear particles, as well as particles characterization, measurement, and modeling techniques are presented through the investigation of a series of contextual works which are emphasized on the identification of these aspects. The review is motivated from the fact that understanding mechanisms involved in wear-induced particle generation, both at nano- and at microscale, is important for many applications that involve surfaces sliding over each other due to various potential health aspects. An attempt has been made to explain how the information based on this broad spectrum of subjects discovered in this contribution can be used and improved in order to produce a more resilient, rational, and versatile knowledge base which has been found lacking in the present literature during its survey. The area of study is highly multidisciplinary since it involves aerosol, particle, and material sciences.
