Abstract

An intensive investigation for detecting source of the heavy metals contamination in different areas (within industry, at roadside, adjacent agriculture lands) of various industries located at two sites A & B were made. Co-relationshipswere determined for specificmetal contamination in leacheates at sites with total contents of heavy metal at source.At siteA, it was observed that the leached fractions were highly correlated with the total contents of all tested heavy metals showing same source of contamination, whereas at site B relation was obtained only in case of Mn i.e 0.99, Zn i.e 0.82 and 0.70 for Cu, while, rest had sparse relationship, showing that the variability in heavy metal contents was caused by the different sources of contamination. The soil samples showed different microbial groups (cfu), in the order Bacteria > Fungi > Actinomycetes > RhizobiumandAzotobacters. The results indicated that the lowavailability of nutrients (NPK) in soil could be due to the heavy metal contamination which reduced the beneficial microbes such as Rhizobia and Azotobacters in contaminated soil.
