Elemental Compositions of Suspended Particles Released from Various Small Sources (II)

Abstract

Suspended particles released from various small facilities of other kinds than those studied in the preceding report were also subjected to multielement analyses, and the values of “elemental concentration ratio” C_R, which was defined in the preceding report, were also calculated.For each facility studied, the elements are listed, whose C_R values are apparently much larger than unity and which are considered to be much enriched in sus-pended particles released from the facility in question.
Although the values of C_R are in general near unity for most elements, they take values appreciably larger than unity for the elements, which are enriched in suspended particles. Therefore, C_R could be regarded as a simple and convenient measure for presuming what kinds of element are important in the contribution of a facility in question to the atmosphere.
