Sažetak
Jarosite waste, originating from zinc extraction industry, is considered hazardous due to the presence and the mobility of toxic metals that it contains. Its worldwide disposal in many tailing damps has become a major ecological concern. Three different methods, namely modified Synthetic Precipitation Leaching Procedure (SPLP), three-stage BCR sequential extraction procedure and Potential Ecological Risk Index (PERI) Method were used to access the ecological risk of jarosite waste disposal in Mitrovica Industrial Park, Kosovo. The combination of these methods can effectively identify the comprehensive and single pollution levels of heavy metals such as Zn, Pb, Cd, Cu, Ni and As present in jarosite waste. The obtained results demonstrate that the ecological risk of heavy metals declines in the following order: Cd>Zn>Cu>Pb>Ni>As. A multivariate statistical method such Principal Component Analysis (PCA) was used to estimate the correlation of the results obtained by SPLP and three-stage BCR sequential extraction analysis.
