Food exposure to heavy metals such as Pb, Cd, Cr, Ni, As, Zn, Cu and Fe is considered
a risk to human health. This study analyzes the level of heavy metals in soil and delicious apple
tissues (fruit, leaf, shoot) in three different rootstocks: mm106, m26 and m9 grown in the Obiliq
region (considered as a polluted region). The data obtained from the Obiliq areas are compared
with those grown in reference clear area. Individual soil samples were collected from each plant
to assess metal content in the immediate plant environment. Samples of soil, fruit, leaf and shoot
have been analyzed for heavy metals (Pb, Cd, Ni, As, Zn, Cu, Cr and Fe) using atomic absorption
spectrophotometry (AAS).
The results indicated that the average concentrations of Pb, Cd, Ni, As, Zn, Cu, Cr and Fe in soil
of Obiliq areas were 2.03, 0.15, 6.99, 12.4, nd, 12.3, 4.68, 5.32 mg kg-1 d.w. respectively. The
concentration of metals in the apple tissue increased with the increase of heavy metals in soil
from polluted area. The accumulation ratios of heavy metals were calculated to assess the
potential health risks. The mean concentrations of the heavy metals in the soil were in order of
magnitude Ni > Zn > Cr > Cu > Fe > Pb > Cd > As while that in the fruits of apple were in order
of magnitude Cr > Fe > Cu > Ni > Pb > Zn > Cd > As; in the leaves were Fe > Zn > Cu > Cr >
Pb > Ni > Cd > As; in shoots were Zn > Fe > Cu > Pb > Ni > Cr > Cd > As.
Mobility of heavy metals and potentially hazardous in studied lands threatens the quality of apple
fruit consumption, with a real risk that these elements (Cd, Pb, Ni and Cr) can enter the food
chain.
