| Research Abstract |
Asian dust particles grew in size during they passed the East China Sea to Japan due to the adherence by sea salt. At the western coast areas of Kyushu areas of Japan, dust particles settling to the surface mixed with sea salt, sulfate, nitrate and chloride in contrast to that particles settled at the coast areas of China were clean(meaning rare contents of the secondary salts). Because of the change of dust particles, dust flux to the surface at Kyushu coast became larger by the factor of several to tens of percentage in comparison with the cases when dust particles did not change. Water-soluble iron was detected in a small number of dust particles and no correlation of its content with the salt was identified. In addition, iron tended to accumulate in smaller particles while calcium tended to in larger particles.
