    Abstract: Based on the fingerprint information (i.e. contents of oxides and trace metals), the present study firstly applied similarity analysis to judge whether solid waste disposal in a former chemical industry plant was intentional. The fingerprint information showed clear influences on the standardized similarity coefficient, and these influences were discussed. The relationship between similarity and divergence coefficients was also well described. By comparing with the fingerprint information of the reference sites, we concluded that the "suspected solid waste disposal" behaviors in all the monitoring sites were actually unintentional. This conclusion was also supported by other information, i.e. depth distribution and species distribution of volatile organic compounds. Standardization of similarity coefficient will be greatly helpful to build the connections between similarity and divergence coefficients, and the cut-off values were tentatively determined as 0.8 and 0.6 for "high similarity" and "possible similarity", respectively. This study proposed a powerful and quantitative tool, which might be useful for environmental management in the future.
