We present in this study accumulate of two heavy metals (Fe - Cu) in the tissues of
flowers , leaves , stems and roots of Lamium moschatum Mill.
The study showed that the plant accumulated (Fe - Cu) in different concentrations ,
with an increase i
n the concentration of (Fe) in all samples specially in roots . The highest
concentration of (Cu) was in flowers (1669.23 mlg/kg) , and for (Fe) was in roots (4539.5
mlg/kg) .
The results showed a convergency in the concentrations of (Cu) in the parts of plant
for the same sample (432.62 - 490.75 - 353.409 - 272.73 mlg/kg) in flowers , leaves , stems
and roots in order . but the concentrations of (Fe) in roots was higher than that in flowers ,
leaves and stems for the same sample .
In sample -5- the value of (Fe) in roots was (1124.91 mlg/kg) but in flowers , leaves
and stems at the same sample was ( 234.83 - 218.82 - 205.24 mlg/kg ) in order.
The aim of this study is to evaluate the role of Bauhinia variegate, Bouganivillea
glabra, Ligustrum vulgare and Ficus brnjamina as bioaccumulators for Nickel. The
concentration of Nickel in the studied plant leaves, bark, wood and soils in Al-Fors
an
Garden (Lattakia City) was determined. The results showed that the Nickel concentration
in the Ficus brnjamina leaves and bark was significantly high (11.04 and 12.37 ppm)
respectively compared to other studied plants, whereas the nickel concentration was
approximately the same in the other studied parts, and approximately the same as its
natural concentration in plants. Our results also showed that the nickel concentration in the
studied soil did not exceed the international norms of children gardens (about 57ppm), but
it was very low regarding the park soils. The relationship between the nickel concentration
in Ficus brnjamina wood and Bouganivillea glabra bark was the most significant.
