Assessment of Heavy Metal Concentrations with Fractionation Method in Sediments and Waters of the Badovci Lake (Kosovo)

Figure 5

Geoacumulation index (I_geo) values for heavy metals in the sediments of the Badovci Lake. I_geo ≤ 0, practically uncontaminated; 0 ≤ I_geo ≤ 1, uncontaminated to moderately contaminated; 1 ≤ I_geo ≤ 2, moderately contaminated; 2 ≤ I_geo ≤ 3, moderately to heavily contaminated; 3 ≤ I_geo ≤ 4, heavily contaminated; 4 ≤ I_geo ≤ 5, heavily to extremely contaminated; 5 ≤ I_geo, extremely contaminated.
