Characteristics of Trace Elements in Jurassic Relict Plant in Qinba Mountain Area

Abstract

In order to explore the source of trace elements in Jurassic coal-forming plants in northern China, Larix chinensis, Larix principis-rupprechtii, Podocarpus macrophyllus, Pinusarmandii. And other trace elements in modern plants and soil samples were studied by ICP-AES. The results showed that the soils had strong enrichment of Ag, As, Mo, Cd and Hg, and had weak enrichment of Cr, Mn, Zn and Pb, and the absorption of the same elements by different plants Ability to differ significantly. 1
