摘要: Abstract An apparatus for monitoring the air quality with regard to metallic aerosol concentrations (ultra-fine powders of metal, dust, flying ash) on-line and in real time is decribed. It similar those used classical optical spectroanalysis: pollutants are atomized, excited ionized an inductively coupled plasma they identified their spectrum. The problems related calibration detection limits obtained this discussed. first results concerning some metals (Be, Co, Cd Pb) shown. preliminary study lower than actual threshold limit values, which considered as upper concentration human health environment.
