抄録

Molecular microprobe optics laser examiner (MOLE) was applied for the identification of components in environmental particulates. Operation conditions were chosen as follows; Ar ion laser (514.5nm), (200400)mW, slit width (300600)μm, Δν= (1001700)cm^-1. Highway tunnel dust taken from a ventillation duct at Hayabusa, Tokyo, was roasted for several minutes at about 500°C for preventing its fluorescence and analysed on a glass plate. α-SiO₂, glassy silica, calcite and (Ca, Mg)CO₃ were identified, and diaspore and carboneous components were suggested their existence. Roasted chromite dust was synthesized with chromite are powder, Na₂CO₃ and CaCO₃ (12:9:5), which were roasted at about 500°C on an iron plate for an hour, ground to under 100 mesh and were served as a sample. From particles smaller than 20μm in size, Na₂CrO₄, CaCrO₄ and (Na₂, Ca)CO₃ were identified together with the original components. These components were dispersed finely smaller than 1μm on particles through the observation of an imagemode pictures.
