ARTICLE DETAILS ABSTRACT Article History: Heavy metals are known as an important group of pollutants in soil. Major sources of heavy metals are modern industries such as mining. In this study, spatial distribution and environmental behavior of heavy metals in the Jajarm Received 20 November 2018 bauxite mine have been investigated. The study area is one of the most important deposits in Iran, which includes about Accepted 21 December 2018 22 million tons of reserve. Contamination factor (CF), the average concentration (AV), the enrichment factor (EF) and Available online 4 January 2019 geoaccumulation index (GI) were factors used to assess the risk of pollution from heavy metals in the study area. Robust principal component analysis of compositional data (RPCA) was also applied as a multivariate method to find the relationship among metals.
