Soil samples collected from various places in and around Mysore were a
nalyzed for the total trace elements such as Fe, Mn, Cu, Zn, Pb, and C
d. The results of the analysis indicate that the concentration of lead
and cadmium in soils is below 2.5 mu g ml(-1) and 0.2 mu g ml(-1) res
pectively, which are the minimum detection levels, whereas the concent
ration of iron, manganese, copper, and zinc in most of the samples is
within the global average ranges of 3%, 500-1000 mu g g(-1), 15-40 mu
g g(-1), and 50-100 mu g g(-1), respectively. The investigated area ha
s the presence of gneisses and schists, in which partly there are igne
ous intrusions and pegmatitic intrusions. There are amphibolite enclav
es in gneisses that account for the higher concentration of trace elem
ents. The lower concentration may be attributed to the presence of sil
icic type of rock.
