—In the present study Particle Induced X-ray
Emission (PIXE) method has been used to identify the elements
present in some environmental samples (soil and vegetable) in
order to show the possible influence of soil in the metal
absorption by the vegetables grown in saline region of
Bangladesh. PIXE can detect a high number of elements with a
high sensitivity (ppm range) in a simple and fast way. The
samples were prepared for irradiation following conventional
methodology and irradiated with 2.5 MeV collimated protons
from the 3 MV tandem accelerator of Bangladesh Atomic
Energy Commission. The X-rays emitted during irradiation
from the samples were measured by HPGe detector and the
acquired X-ray spectrum was analyzed by using the software
GUPIXWIN. The obtained results were compared with two
standard values IAEA-359 (cabbage) and IAEA Soil-7.
Concentrations of some heavy metals (Cr, Co and Ni) were
found above the potentially risky levels in soils; however, they
accumulated in plants to a lesser amount, probably because of
the physical and chemical properties of soils that prevent their
conduction to vegetables. As, Cd and Pb were not found in any
one of the soil and vegetable samples in the present study.
