Abstract
The shape and elemental composition of individual emission particles (10 species) have been determined using SEM-EDS.
As for the shape, particles released during the burning of coal, kerosene oil and heavy oil ranked C were observed as spheric particles. As for the elemental composition, coal, kerosene and heavy oil ranked A-C contained Ti and V, respectively. Especially, Ni was contained in heavy oil raked C. From these results, Ti, V and Ni seemed to be tracer elements to distinguish such particles from atmospheric particles.
Furthermore, we have made an attempt at the spider's model method that was one of the distinguishable methods of emission particles. As the results, coal and soil particles were classified as 3 or 4 types, respectively. The other emission particles have uniform composition and were classified as only 1 type, respectively.
Based on these results, the characteristic particles derived from specific emission particles were recognized in the general atmospheric particles.
The chemical compound of such particles were further estimated using scanning X-ray images.
