Abstract

Heavy metal contamination of soils is
widespread and induces a long-term risk to ecosystem
health. This research focuses on the heavy metal
contamination, transfer values and risk assessment in
the Kočani Field plant system (Republic of Macedonia).
To identify the heavy metal concentrations in
Kocˇani crops (rice and maize), the geochemical
analysis was performed by inductive coupled plasma
mass spectrometer and thereupon the transfer factor
(TF) and estimated daily intake amount values were
calculated. The highest As, Cd, Mo, Pb and Zn values
were determined in the rice samples grown in the
paddy fields near the Zletovska River. The highest Pb
and Mo concentrations measured in the maize samples
were from the maize fields near the Zletovska River
and Ciflik city. High TF values for Mo, Zn, Cd and Cu
revealed a strong accumulation of Mo, Zn and Cd
by rice and Mo and Zn by maize crops. The results of
the estimated daily intake showed that the regular
consumption of rice and maize crops containing the
highest Cd, Mo, Pb and Zn concentrations could pose
a serious threat to human health, because the daily
intake of Cd, Mo, Pb and Zn for crops grown in the
fields around the Zletovska River exceeded the
recommended provisional tolerable daily intake values.
Taking into account the results, the area around
Zletovska River is considered as the most anthropogenically
impacted part of Kočani Field.
