Suspended particles released in glass manufacture were subjected to multielementanalysis by means of instrumental neutron activation method and energy dispersive X-ray fluorescence spectrometry. Suspended particles released from glass factories using combustion heating generally consist of both particles emitted from glass fusion and particles produced through fuel combustion. Elemental compositions of suspended particles emitted from glass fusion were found to be strongly dependent on the kind and recipe of raw materials and additives. Of the various metallic elements involved in suspended particles emitted from glass fusion, the elements, As, Se, Cd, Sb, Pb and so on are regarded to produce the most serious air pollution. The amount of emission of these elements to the environment is, however, quite varied from factory to factory. The replacement of oil combustion by electric furnace in an opal glass factory remarkably reduced the emission of metallic elements to the environment.
