evaluation of the heavy metal accumulation capacity of a sahraria plant aristida pungens l.

in this work, we aimed at evaluating the xerophytic character by determining the content of seven heavy metals (fe, zn, cu, co, cd, ni, and pb) in the different organs of a sahrian plant aristida pungens l. by atomic absorption spectrometry (saa) and this to use this plant in to clean it up from contaminated soils. the xerophytic trait of aristida pungens l. that allows it to accumulate metals has been confirmed. aristida pungens l. has been shown to have a great capacity to accumulate heavy metals, particularly copper and lead. the contents of its heavy metals range in the threshold of toxic concentrations of fodder plants.
