TI  - Exposure assessment of carbon nanotube manufacturing workplaces.

AB  - Seven CNT (carbon nanotube) handling workplaces were investigated for exposure 
      assessment. Personal sampling, area sampling, and real-time monitoring using an 
      SMPS (scanning mobility particle sizer), dust monitor, and aethalometer were 
      performed to characterize the mass exposure, particle size distribution, and 
      particle number exposure. No workplace was found to exceed the current ACGIH 
      (American Conference of Governmental Industrial Hygienists) TLVs (threshold limit 
      values) and OELs (occupational exposure levels) set by the Korean Ministry of 
      Labor for carbon black (3.5 mg/m(3)), PNOS (particles not otherwise specified; 3 
      mg/m(3)), and asbestos (0.1 fiber/cc). Nanoparticles and fine particles were most 
      frequently released after opening the CVD (chemical vapor deposition) cover, 
      followed by catalyst preparation. Other work processes that prompted nanoparticle 
      release included spraying, CNT preparation, ultrasonic dispersion, wafer heating, 
      and opening the water bath cover. All these operation processes could be 
      effectively controlled with the implementation of exposure mitigation, such as 
      engineering control, except at one workplace where only natural ventilation was 
      used.
