講題:Asian dust, a gift from the continental desert to reduce radiocesium transfer risk
from soil to plant

主持人:傅慶州 助研究員

Abstract:
Asian dust is known to contribute greatly to the marine nutrient cycle. Their role to improve
soil functions has been paid little attention. Fine-mica, which is one of the main components
of Asian dust, has a specific adsorption site for radiocesium. Therefore, we hypothesized that
Asian dust contributes greatly to increase the ability of soils in Japan to retain radiocesium,
and therefore to reduce the soil-to-plant transfer risks after the Fukushima Dai-ichi nuclear
disaster. In this seminar, I will introduce how we can estimate the incorporation of Asian dust
in soils by using isotopic analysis. Then, I will introduce several case studies to clarify the
actual contribution of Asian dust to increase the ability to retain radiocesium in Japan.
