The OECD Working Part on Manufactured Nanomaterials (WPMN) has developed guidance on the initial assessment of emissions from nanomaterial processing, based on the use of hand-held sampling instruments in combination with membrane sampling.
Intensive studies are researching the pathways through which carbon nanotubes (CNT) can enter the body and determining levels of exposure in workplaces to develop guidelines for the safe use of nanomaterials in the workplace.
The focus of this report was to investigate the possible approaches for detecting nano-objects that are formed from airborne CNTs – specifically very fine multi-walled CNTs used for the manufacture of optically transparent CNT sheet electrodes or CNT yarns.
