| Research Abstract |
The method for occupational exposure assessment of multi-walled carbon nanotubes (MWCNTs) is required. The process having the highest probability of exposure to MWCNTs is handling of powdery MWCNTs, but handling CNT-containing products also should have high probability of exposure to MWCNTs at low concentration. MWCNTs are one type of graphitic carbon, therefore, they can be determined as graphitic carbon by carbon analysis. There are wide range of structure and work environment of MWCNTs. In order to determine MWCNTs separately from various interfere, conditions of carbon analysis were examined, for example, different crystallinity of MWCNTs, interfere from background graphitic carbon in the environment or organic resin released from CNT-composites, etc. Exposure assessment method for airborne MWCNT was proposed.
