Analytical characterisation of inorganic suspended matter in the Milan urban aerosol by micro FT-IR spectroscopy

Micro FT-LR spectroscopy has been used to characterise analytically the solid inorganic component of the urban aerosol of Milan. The results of this technique together with those of electron probe micro analysis coupled with scanning electron microscopy (SEM-EDX: are full of promise and lead us to foresee the possibility of interesting applications in the field of study of inorganic species present in urban aerosols. Compared to EDX, micro FT-IR spectroscopy offers the advantage of characterizing with high efficiency a notable number of inorganic compounds present in the aerosol.
