摘要:

The elemental composition of Mount St. Helens ash samples and the amount of water‐leachable trace elements from the ash samples have been measured by inductively coupled plasma emission spectrometry and atomic absorption spectrometry. The leachable fraction of metals ranges from zero to 12 percent. It is speculated that the metals present in the leachates are mainly in colloidal form.
