Geo-Accumulation Index of Heavy Metals in Pond Water Sediment of Raipur
Problem-based learning (PBL) has been implemented to replace classical teaching method with college system in UnderSediment can accumulate trace elements in the environment. An investigative study was carried out to determine the heavy metal in the pond water sediment (n=10) samples of Raipur city Chhattisgarh. The samples were digested and analyzed for extractable metal i.e. Cd, Cr, Cu, and Pb. The extent of elemental pollution was evaluated using with the enrichment factor (EF) and geoaccumulation index (Igeo). The assessment of heavy metal was derived using the geoaccumulation index (Igeo). This study revealed that the sediment is predominantly by Cr < Pb ≈ Cd < Cu < Zn. The data reveal elevated concentrations of Cu (6.4 - 15.3 mg kg-1), Cu( 8.5-14.2 mg kg-1) Pb (0.8 -3.9 mg kg-1) and Cr (6.5-17.2 mg kg-1) and Zn( 6.4 – 21.2 mg kg-1). Except for Cr, other heavy metals have been accumulated (EF>0.5). The highest EFs of Cu, Cd, Pb and Zn are 0.6, 0.7, 0.86 and 0.86, respectively. The Igeo and EF revealed that location 9 and location 10 were extremely enriched with all heavy metals. All location posed high ecological risk (0.5), except location1, which had moderate ecological risk. The outputs from this study are expected to provide the background levels of pollutants and help develop regional sediment quality guideline values in the present studied area.
