STUDY ON SOIL PROPERTIES OF THE EARLY ECOLOGICAL RESTORATION FOR A CHEMICAL LANDFILL IN HUAINAN
The soil properties after ecological restoration for 16 months for a chemical landfill in Huainan should be monitored for the purpose of making sure the early restoration work was going on in an effective way. On the basis of field investigation, the related parameters of soil properties were evaluated by various techniques, including AAS (Atomic Absorption Spectroscopy), pH analyzer and soil organic matter analysis. The results showed that the physical nature of soil had got certain improvement. The pH value had remarkably decreased from 10.3～10.6 to 7.76～8.28 by pH analyzer and the soil contained highly organic matter and nitrogen, but lack of phosphorus and potassium. The effects of heavy metals such as Cu, Cd, Pb, Zn were also discussed in detail on the basis of ecological risk assessment. The concentration of heavy metals were higher than the background value in different extent, and it was calculated that there are approximately 61.5％ of this area in slight ecological risk grade and only Cd was in slight ecological hazard.
