Abstract
In the present paper the results of the qualitative spectroscopic studies on the microchemical elements in raw woods, green trees and the forest soils using alternating current spark are reported. 1.) Spectrums of raw wood samples and various parts of a green tree were lighter than those of their ash. But the qualitative determination of 12 elements (Fe, B, Si, P, Mg, Mn, Al, Ca, Cu, Na, Ti, and K.) was possible. 2.) According to the results of the qualitative spectroscopic analysis of raw woods, there were rather little difference in the kinds and contents of inorganic chemical elements, which is due to the folllowing factors: a.) species. b.) specific gravity. c.) spring and summer woods. d.) heart and sap woods. e.) normal and compression woods. 3.) In the samples of green trees, the results of the qualitative spectroscopic analysis showed little differerence among the several parts of a tree. But the quantitive difference of following five elemnts was found, Si, Mn, Mg, Ca, and P: the leaf and bark were richer in these elements than in the other parts of a tree. 4.) The contents of inorganic elements of forest soils were found different according to the conditions of the collecting spots. It seems that the contents of inorganic elements in leaves of trees are intimately connected with those of the forest soils.
