Description
Winter rain, fresh snow, rime and glaze samples were collected on the top of Mt. Kajigamori (ALT. 1400 m), which is the watershed protection forest of Riv. Yoshinogawa with an altitude of 1400 m, Kochi, Shikoku Island in West Japan during the winter season of 2010 (December 2009 and March 2010). Lead and cadmium in the rain, snow, rime and glaze were analyzed by graphite furnace atomic absorption spectrometry together with the ionic components (Na+, NH4+, K+, Mg2+, Ca2+, F−, Cl−, NO2−, Br−, NO3−, PO43−, SO42−) by ion chromatography, and pH, E.C. during the winter season. In the back-trajectory over Russia-Japan Sea, very low concentrations of Pb and Cd were observed in all samples. From the back-trajectory over North China and Korea, it was considered that the observed relatively high concentration of Pb in snow and rime and Cd in rain showed a possibility of long-range transportation from the East Asis region. The low concentration of lead in rime ice and fresh snow collected at Mt. Tateeboshiyama (ALT. 1299 m) in Shobara city, Hiroshima (Mt. Hibasan quasi-national park) was observed with back-trajectry over Russia-Japan Sea.
