the bed rocks suggesting that factor-1 has geogenic sources. Factor-2
contributed 22.794% to the total variance with a high loading on Mg
(r=0.834), Fe (r=0.771), Ni (r=0.970) and Cr (r=0.961). Mg, Fe,
Ni and Cr level could have been influenced by leaching of mafic and ultramafic
rocks and mining of chromites ore deposits. It means that
factor-2 also has geogenic and anthropogenic sources. Factor-3 contributed
13.893% to the total variance with a high loading on Mn
(r=0.937) and Zn (r=0.933). Mn and Zn levels are also influenced
by leaching of mafic rocks, suggesting that factor-3 also has geogenic
sources. Factor-4 contributed 10.457% to the total variance with a
high loading on pH (r=0.927) and Cu (r=0.900). pH and Cu levels
are probably influenced by agriculture activities. It means that
factor-4 has anthropogenic sources. Factor-5 contributed 8.173% to
the total variance with a high loading on Cd (r=0.864). Cd level is
probably influenced by leaching of local mafic and ultramafic rocks.
It means that factor-5 also has geogenic sources. Factor-6 contributed
6.624% to the total variance with a high loading on Ca (r=0.617). Ca
