Testing dustiness of nanomaterials with a rotating drum
Journal Title: Podstawy i Metody Oceny Środowiska Pracy - Year 2015, Vol 31, Issue 1
Abstract
Nanotechnology is a fast-growing area in many industries. Therefore, research related to potential risks (especially inhalation exposure) linked to the processes of production and handling of nanomaterials is even more important. Dustiness of nanomaterials is a major risk factor in inhalation exposure to airborne particles released from powdered nanomaterials. There are many methods for evaluating the dustiness of materials. Most of them use gravimetric analysis, which is insufficient to characterize dust released from nanomaterials. Since dustiness is a parameter that depends not only on the properties of a material, but also on the method of its determination, it is necessary to develop a standardized approach. This has been commissioned by the European Commission. This paper describes issues related to methods of testing dustiness, adapting existing methods and creating new methods for characterizing dust released from nanomaterials. It also describes a method of testing dustiness of nanomaterials with a small rotating drum. This method generates an aerosol under controlled conditions during drum rotation. Dust released during the process is analysed gravimetrically and by counting.
