摘要

Contamination soil by heavy metals is an increasing environmental issue. The concentrations of 6 metals in the soils sampled in 1991 and 2011 from the 17 cities of Anhui Province (China) were investigated. Tow pollution indexes models were employed to investigate the soil environment quality of 17 cities. The results showed that the concentration of Mn is the highest. During the past 20 years, the concentrations of Cd, Mn and Cu in soil increased gradually. Based on the tow assessment method, environmental quality were assorted as class I (Excellent) or Class II (Good) for each soil with single-factor index method, and most was identified to be class I for the soils with the comprehensive index model. In comparison with the single-factor index method, the comprehensive index model concerned both dominant parameter and average contribution of all factors to the integrated environmental quality.
