Abstract |
|
|
| The studied area is located within the North Abu Rusheid region, Southeastern Desert, Egypt, specifically between latitudes 24° 36 30 N and 24° 37 15 N, and longitudes 34° 46 15 E and 34° 46 45 E. The soil and plant samples were chemically analyzed for radioactive and trace elements determination by using ICP-AES or ICP-MS techniques. The study focuses on the concentration and accumulation of certain radioactive and some trace elements, including U, Th, Ni, Cd, Mo, Co, Pb, and Zn in Louts hebranicus, assessing the potential of this species for identifying new locations. The U, Th, Ni, Mo, Cd, and Zn concentrations observed in the soil samples fall below or within the permissible threshold for soil, while the lead concentrations exceed the levels suggested by the World Health Organization (WHO). Bioconcentration factor (BCF) values indicate that Lotus hebranicus sp. can absorb and accumulate uranium at a rate 115 times and thorium at a rate 154 times greater than the global average for desert plants indicating that Lotus hebranicus could be classified as a hyperaccumulator of uranium and thorium. The findings suggest that Lotus hebranicus is capable of absorbing and storing thorium in greater quantities than uranium. Lotus hebranicus can concentrate Pb, Ni, and Cd with elevated rates, thus this plant should be avoided in cattle forage. Zn, Co, and Mo uptake levels exhibit that Lotus hebranicus is a viable candidate for exploration and phytoremediation of these elements. Lotus hebranicus can concentrate certain elements more effectively than others, in the following order: Ni > Pb > Co > Th > Mo > U > Cd. |
