Paper Title:
Ecological Risk Assessment of Heavy Metals in Contaminated Soil Based on Engineering Fuzzy Set Theory
  Abstract

It is not easy to handle relativities of metals toxicology and ecological risk grades, especially, fuzzy in realization of soil heavy metal pollution, when the method suggested by Hakanson was used to assess ecological risk. To explore a better way to solve this problem, certainty in ecological risk grades was fuzzed through engineering fuzzy set theory, and a fuzzy mathematic model was built. The model was then applied in Xiaoqinling gold mining regional, which was selected as case study and where soil was polluted by heavy metals over decades, and its results were compared with that from Hakanson method. The results showed that the fuzzy mathematic model was a better way for ecological risk assessment of heavy metals in contaminated soil.
