An Investigation on Soil Quality and Heavy Metal Levels in Soil of Rajbandh Waste Disposal Site At Khulna, Bangladesh

The principle objective of this study was to evaluate the soil quality and the level of contamination of soil by heavy metals adapting various developed index in a selected waste disposal site at rajbandh, khulna, bangladesh. to theses endeavor, ten soil samples were collected from the selected locations and then the relevant elements of al, fe, mn, cr, cu, pb, zn, ni, cd, as, co, sb, sc and hg were measured and monitored using standard method. to estimate the contamination situation of soil, contamination factor (cf), enrichment factor (ef) and geo-accumulation index (igeo) and potential ecological risk index (peri) were computed using geological background values. in addition, for assessing soil quality, pearson's correlation coefficients analysis was also performed. furthermore, this study revealed that the values of cf and igeo in soils around the waste disposal area affected from the contamination of heavy metals mostly by pb, cd and sb. in contrast, pearson's correlation indicated that the sources of metals are almost the same and these heavy metals might be derived from the waste accumulation activity. dump sites have great potential for energy extraction if the high valued compounds to be extracted.
