AB  - We evaluated the robust, lightweight DiSCmini (DM) aerosol monitor for its 
      ability to measure the concentration and mean diameter of submicrometer aerosols. 
      Tests were conducted with monodispersed and polydispersed aerosols composed of 
      two particle types (sodium chloride [NaCl] and spark-generated metal particles, 
      which simulate particles found in welding fume) at three different steady-state 
      concentration ranges (Low, <10(3); Medium, 10(3)-10(4); and High, >10(4) 
      particles/cm(3)). Particle number concentration, lung deposited surface area 
      (LDSA) concentration, and mean size measured with the DM were compared with those 
      measured with reference instruments, a scanning mobility particle sizer (SMPS), 
      and a handheld condensation particle counter (CPC). Particle number 
      concentrations measured with the DM were within 16% of those measured by the CPC 
      for polydispersed aerosols. Poorer agreement was observed for monodispersed 
      aerosols (+/-35% for most tests and +101% for 300-nm NaCl). LDSA concentrations 
      measured by the DM were 96% to 155% of those estimated with the SMPS. The 
      geometric mean diameters measured with the DM were within 30% of those measured 
      with the SMPS for monodispersed aerosols and within 25% for polydispersed 
      aerosols (except for the case when the aerosol contained a substantial number of 
      particles larger than 300 nm). The accuracy of the DM is reasonable for particles 
      smaller than 300 nm, but caution should be exercised when particles larger than 
      300 nm are present. [Supplementary materials are available for this article. Go
