AB  - Continuous monitoring for possible exposure to carbon nanotubes was conducted 
      over a period of 2 to 3 days at workplaces that manufacture multiwall carbon 
      nanotubes (MWCNTs) and single wall carbon nanotubes (SWCNTs). To estimate the 
      potential emission of carbon nanotubes (CNTs) and potential exposure of workers, 
      personal sampling, area monitoring, and real-time monitoring using an scanning 
      mobility particle sizer (SMPS) and dust monitor were conducted at workplaces 
      where the workers manufactured CNTs. The personal and area sampling of the total 
      suspended particulate (TSP) at the MWCNT manufacturing facilities ranged from 
      0.031 to 0.254 and from N.D (not detected) to 0.253 mg/m(3), respectively. This 
      2- to 3-day monitoring study found that nanoparticles were released when opening 
      the chemical vapor deposit (CVD) reactor door after the synthesis of MWCNTs, when 
      transferring the MWCNTs to containers and during blending and grinding. However, 
      distinguishing the background concentration from the work process particle 
      emission was complicated due to sustained and even increased particle 
      concentrations after the work processes were terminated. The MWCNTs sampled for 
      transmission electron microscopy (TEM) observation exhibited a tangled shape with 
      no individual dispersed CNT structures.
