Abstract

Heavy metal contents in railway rock-cut slope soil have directly influenced ecosystem on rock-cut slope and eco-environment safety of farmland nearby. In the study heavy metal Pb, Cd, Zn, Cu and Mn was determined by AAS in railway rock-cut slope and control soil samples on Cheng-Da Railway crossing purple soil in Sichuan province. The results showed that Pb and Mn were significantly higher in rock-cut soil than in control soil, that is 29.7%~35.4%, while Cd, Zn and Cu were similar in both soils.
