| Research Abstract |
This study was initiated to better elucidate behavior of iron in aerosols around Ryukyu archipelago, coral reef rich environment. Iron is a micronutrient that affects marine ecology. We investigated chemical compositions and transformation and photochemical characteristics of iron species (Fe(II) and Fe(III)) in aerosols collected at Cape Hedo Aerosol and Atmosphere Monitoring Station (CHAAMS), Kume Island (ca. 100 km west of Naha city) and Minami-Daitou Island (ca. 360 km east of Naha city).
