An environmental field assessment of soil quality and phytoremediation of toxic metals from saline soil by selected halophytes.

The current study has aims to investigate the soil quality and phytoextraction of cadmium (Cd), chromium (Cr), and lead (Pb) from saline soils using (camelthorn), (saltcedar), (mustard bush), and (bush seep weed). The saline bulk soil, rhizospheric soil, and different parts of selected plants were oxidized using the acid mixture and determined Cd, Cr, and Pb by atomic absorption spectrometry. The bio-concentration factor (BCF) and translocation factor (T) of also examined. The quality parameters of soil like pH (< 8.5), and electrical conductivity (EC; > 4.00 dS m) indicated the soil is saline. The salinity of soil was lower the organic matters, and total nitrogen contents in studied saline bulk soil due to deterioration condition of soils. However, the rhizospheric soil showed the improved quality of saline soil reflected the good phytoextraction of salts from saline soil. The high contents of Cd in roots and shoots (1.02 and 0.65 µg g) of , Cr in the roots and shoots (6.20, and 6.75 µg g) of and Pb in the roots and shoots (5.63, and 5.75 µg g) of . The BCF and T showed the and for Pb, , and for Cr considered as hyperaccumulator plants. Based on BCF and T values of , for Cd, and for Cr and Pb have the efficiency to uptake toxic metals from saline soil. Thus, it can be concluded that selected plant species may have ability for the phytoextraction the Cd, Cr and Pb from saline soil.
