Description 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.
