Study on Remediation Technologies of Organic and Heavy Metal Contaminated Soils

Soil pollution is a global problem which has gained enormous attentions especially in China. The Institute of Applied Ecology, Chinese Academy of Sciences is the first research institute to study remediation technology for contaminated soils. In the 1990s, this institute carried out the Major Programs of Chinese Academy of Sciences, namely, “Study of clean technology on contaminated soil.” Since the year 2000, the Environmental Engineering Group and Pollution Ecology Group of the Institute of Applied Ecology have carried out much research on the mechanisms, technology, materials, and equipment required for the remediation of soils contaminated by organic pollutants and heavy metals. They have undertaken 46 projects on soil remediation supported by the Chinese government and Chinese Academy of Sciences, such as the National High Technology Research and Development Program of China (863 Program), the Major State Basic Research Development Program of China (973 Program), the National Natural Science Foundation of China, and the Major Programs of the Chinese Academy of Sciences. Many significant results have been obtained, including 6 remediation technologies, 5 remediation equipments, 10 remediation materials, and the publication of 46 patents and 67 papers.
