大熊猫毛发中无机元素的初步研究

A PRIMARY STUDY ON THE INORGANIC ELEMENTS IN THE HAIRS OF GIANT PANDAS

The 21 inorganic elements including Al, Ti, V, Cr, Se, As, Hg, P, Cu, K, Zn, Fe, Mn, Ca, Mg, Pb, Cd, Co, Ni, Sr and Ba in the hairs of 18 healthy giant pandas in domestic and field were determined. We found that the content of Hg in the hairs of field Pandas increases with the rising of the Panda ages the contents of 10 elements such as Hg in the hairs of field old Pandas are the highest; the quantities of 13 elements such as Al in the hairs of field male Pandas are higher than that of fema-les; the contents of 11 elements such as Ti in the hairs of field Pandas are higher than that of domestic ones; the contens of Hg,Cu, Pb, and Cd in the hairs of domestic Pandas increase with the rising of the Pandas' age; there is no significant difference between the element content in the white hairs and that in the black hairs of the same old panda in field.
