Abstract

Contamination of soils with heavy metals is
widespread and poses a long-term risk to ecosystem health.
Abandoned and active mining sites contain residues from
ore-processing operations that are characterised by high
concentrations of heavy metals. The distribution and
mobility characteristics of heavy metals (As, Cd, Cu, Pb,
and Zn) in paddy soil samples from Kocˇani Field (Macedonia)
using ICP-EAS and a sequential extraction procedure
was evaluated. The results indicate that highly
elevated concentrations of As, Cd, Cu, Pb, and Zn were
detected in the paddy soil sample from location VII-2 in the
vicinity of Zletovo mine and Zletovska river in the western
part of Kocˇani Field, which drains the untreated acid mine
waters and mine wastes from the active Zletovo mine. The
degree of contamination based on index of geoaccumulation
(Igeo) from strong to weak in the paddy soils samples is
Pb[As[Cd[Zn[Cu. The mobility potential of
heavy metals in all paddy soil samples increases in the
order As\Cu\Pb\Zn\Cd. According to the results
of the anthropogenic impact on the paddy soils, a further
study on the heavy metal concentrations in rice and other
edible crops, the remediation process of the paddy soils and
a dietary study of the local population are needed.
