Concentrations of Alkali and Alkaline Earth Elements in Mushrooms and Plants Collected in a Japanese Pine Forest, and Their Relationship with ~137Cs

摘要

~137Cs and stable Na, K, Rb, Cs, Mg, Ca, Sr, Ba and Al were determined in 29 mushrooms and 8 plants collected from a Japanese pine forest. Concentra- tions of ~137Cs, Cs and Rb in mushrooms were one order of magnitude higher than those in plants growing in the same forest. On the other hand, concentra- tions of Ca and Sr in mushrooms were obviously lower than those in plants. A good correlation (r = 0.99, p < 0.01) between ~137 Cs and stable Cs concen- Trations was observed for mushrooms.
