AB  - Many studies show that particle toxicity increases with decreasing their size, 
      emphasizing the role of submicrometric particles, in particular of ultrafine 
      particles (<100 nm). In fact, particles greater than 2.5 mum are quickly removed 
      through dry and wet deposition on the timescale of hours whereas submicrometer 
      particles may reside in atmosphere for weeks, penetrate in indoor environment, 
      and be long-range transported. High aerosol size resolution measurements are 
      important for a correct assessment of the deposition efficiency in the human 
      respiratory system, and time resolution is another important requisite. Starting 
      from such considerations, time-resolved aerosol particle number size 
      distributions have been measured in downtown Rome. Fast Mobility Particle Sizer 
      (FMPS) and Scanning Mobility Particle Sizer (SMPS) measurements have been carried 
      out at the INAIL's Pilot Station, located in downtown Rome, in an area 
      characterized by high density of autovehicular traffic. The two instruments have 
      allowed to investigate deeply the urban aerosol in the range of 5.6-560 and 
      3.5-117 nm, respectively. In particular, the FMPS measurements have confirmed the 
      interpretation about the transition phenomena in the time interval of few 
      seconds, timescale typically associated with the emission of gasoline and diesel 
      engines. In downtown Rome, the hourly average size distribution is bimodal or 
      trimodal with maxima at about 5-15, 20-30, and 70-100 nm. Particle formation in 
      the nucleation mode was associated to freshly emitted autovehicular exhaust.
