摘要: The article presents the geochemical and biogeochemical characteristics of heavy metal elements within the soil-plant system in the Hetai mine-abandoned areas and wasteland, China. The cytogenetic toxic effects of gold mine wastelands environment on the chromosome and micronucleus were analyzed by genetic methods. The results showed that abundances of Au and Au-associated heavy metal elements such as Cu, As, Cd, Pb and Hg in soils, plants and the pigments in those abandoned mine areas were much higher than those in the background region. The cell structures of the plants in the abandoned mine areas were anomalous and aberrant, and there were many nano-metal particles diffused in the cells. Moreover, the heavy metal elements in those abandoned mine areas had entered the ultrastructure and caused toxicities to the organism.
