Characteristics and flux of minerals input into the East China Sea by dry deposition

由于海盐的附着，亚洲尘埃颗粒在通过东海到日本的过程中尺寸变大。在日本九州地区的西部沿海地区，沉降到表面的尘埃粒子与海盐、硫酸盐、硝酸盐和氯化物混合，而在中国沿海地区沉降的粒子是干净的（意味着二次盐的含量很少）。由于尘埃粒子的变化，尘埃通量的表面在九州海岸变得更大的几个到几十个百分点的因素相比，当尘埃粒子没有变化的情况下。水溶性铁检测到少量的灰尘颗粒，其含量与盐没有相关性被确定。此外，铁倾向于在较小的颗粒中积累，而钙倾向于在较大的颗粒中积累。

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.
