摘要:The present work was conducted to know the correlation between soil properties with heavy metal concentrations by cluster analysis in industrially polluted soil in Mysore, Karnataka. Mean metal concentrations for Fe, Cu, Zn, Ni, and Cr were 32.12 mg/kg, 52.72 mg/kg, 44.72 mg/kg, 10.86 mg/kg and 8.01 mg/kg respectively. The relationship between different physico-chemical properties and heavy metal concentrations were analyzed by Pearsons correlation coefficient. The correlation matrix, were moderate correlations between water holding capacity and Chromium with r values 0.651. Similarly a moderate correlation was found between Moisture content and Iron with r values 0.631 present in the soil sample. Apart from Moisture content and water holding capacity with heavy metal content such as Iron and Chromium, there is no significant correlation was found between rests of the soil properties with respect to other heavy metal content. The association with heavy metals and the similarity values were done by bray-Curtis similarity analysis. The values above 90% are only to be taken account to the distribution and occurrence of heavy metal contents in respective study sites. The species of heavy metals which shows the higher and constant similarities viz., in sites IS-6 and IS-8, IS-3 and IS-9. The lowest similarity observed in the sites of IS-1 and IS-7 was interlinked with other sites of the study area. Cluster analysis of the heavy metals in different study area was also observed and it indicates anthropogenic activities and natural origins.
