Abstract
The state of inorganic substances in soup made by boiling the shellfish lived in Ariake Sea was studied.
Magnesium, sodium, potassium and calcium were found mainly in the ionic state and the amount of these elements extracted in the soup was more than that of other elements.
Iron and copper were found largely in the organic compounds, and their amounts in the soup were small.
Elements existing in the shellfish in extremely small amount were indium, titanium, strontium and aluminium.
