摘要: The concentrations of fifteen metals (Mg, Na, Ca, K, Se, Zn, Mn, Fe, Pb, Cr, Cu, Cd, Sb, Ni, Co) were determined in water from ten artesian wells (AW) in Semberija to obtain a general metal profile this region. Principal components analysis (PCA) was used classification. Using principal component two factors controlling the variability obtained, which accounted for nearly 71.5% total variance. Natural (lithogenic) factor is represented by PC1, while anthropogenic factor PC2. PC1 with high contribution Mg, Zn and Se accounting 41.84% variance, PC2 exhibits high loading Cr Pb (29.66%). Three areas (clusters) different characteristics detected. Water wells first cluster (AW1, AW2, AW3, AW4, AW5 AW6) had much higher metal concentration compared those second (AW7, AW8 AW9) third (AW10). That as result inputs. Also, the demonstrated slightly elevated values Mn (concentrations up 0.176 mg/L), other investigated elements are below recommended World Health Organization (WHO) United States Environmental Protection Agency (US EPA).
