Efficiency of some plant species on heavy metals accumulation on Mehd Aldhahab gold mine, Saudi Arabia
Mahad ADDahab Mine is the oldest one in Saudi Arabia. Their soil was reported as highly contaminated with Cd, Cu, Pb and Zn and low contaminated with As. Therefore, samples from different plants species have been selected to study their ability to accumulate these heavy metals. Although significant differences were not found at 0.01 levels among the plant species, it was found that Pergularia tomentosa was the highest to accumulate heavy metals. Considering the mean of accumulating heavy metals, plant species accumulated heavy metals by this order: Pergularia tomentosa>Euculeptus Sp>Convolvalus Sp.>Family Graminaea> Rhiza strica>Acacia tortilis>Prosopis juliflora>Salsola Sp>Calotropis procera>Ochradenus baccatus. According to the mean of BAFs, the concentration of Cd was found to be significantly different from that of Cu, Pb, and Zn. From above, these plants should be described as not-excluder and can be explored further for phytoremediation of metal polluted soils. On the other hand, the practice of providing foliage and pods as fodder for live stock should be avoided in Mahad ADDahab area.
