Concentrations of iron found in the bulb of
carrot (825.51 mg/kg), in stem (506.03 mg/kg) and in
leaves (1207.18 mg/kg) of cucumber were over the
allowable maximum limit of iron in vegetables; of
425.5 mg/kg. Iron concentrations are higher in leaves
of bean and pea plant compared with the others parts
of these plants.
While Cu concentration was under detection
limit in bulb of carrot, a high concentration of Cu
(157.84 mg/kg) was detected in carrot leaves, which
is over the allowable maximum limit (73.3 mg/kg).
All the studied samples are under the
recommendable maximum limit of Mn in vegetables
(500 mg/kg).
Iron concentrations found in fruits are in
higher quantities than the other studied metals.
The above results show that content of the
investigated elements in various vegetables depends
on the organ of the plant, the growing stage and also
on the level of area pollution.
