Abstract

The second and third glaze events in Shikoku region were observed to have arisen during the early morning in March 9/2012 and January 14/2013, respectively. In order to obtain information about the concentrations of chemical constituents in glaze, one of the samples was collected from the summit of Mt. Kajigamori (ALT. 1400 m), where is the watershed protection forest of Riv. Yoshinogawa is located. The concentrations of major soluble ions and toxic elements, such as Cd and Pb, were analyzed. High concentrations of nss-SO42− and Pb were observed with the back-trajectory over Middle and North China. The residues in the glaze were analyzed by a SEM-EDX technique. In the residue, various components of small spherical particulate were also found, indicating the presence of various origins of the fly-ash, including coal burning with the effect of long-range transport.
