As multi-wall carbon nanotubes (MWCNTs) come to be used in a wider range of products, increasing production is expected to result in greater exposure of workers to MWCNTs. In this research, we present a method for evaluating the concentration of MWCNT aerosols distinctively on the basis of the elemental carbon (EC) concentration. Respirable dust is sampled using a Sioutas cascade impactor (SCI) for a certain volume of workplace air. The SCI can collect size-segregated particles having… CONTINUE READING
