Abstract:The contents of eight metal elements, such as Au, Pb, Cu, Zn, Ca, Mg, Hg and As in Pogonatum neesii (C. Muell.) Dozy and soil on Lateritic Gold Deposit in Southwest Guizhou Province were analysed by Atomic Absorption Spectrometry, and the correlationship between plant and metal elements, and the accumulation of the moss to metals were further discussed. The results showed that the metal contents in P. neesii were higher than in soil, and the accumulation capacity of the plant to different metals varied greatly. Ca-Mg showed significantly coefficient at 0.01 level, so did Cu-Zn and Hg-As at 0.05 level. P. neesii had strong accumulation function to Hg and As elements.
