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

AbstractThe current study has aims to investigate the soil quality and phytoextraction of cadmium (Cd), chromium (Cr), and lead (Pb) from saline soils usingAlhagi maurorum (camelthorn),Tamarix aphylla (saltcedar),Salvadora persica (mustard bush), andSuaeda nigra (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 (TF) of also examined. The quality parameters of soil like pH (<  8.5), and electrical conductivity (EC; >  4.00 dS m−1) 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−1) ofAlhagi maurorum, Cr in the roots and shoots (6.20, and 6.75  µg g−1) ofTamarix aphylla and Pb in the roots and shoots (5.63, and 5.75  µg g−1) ofSuaeda nigra. The BCF and TF showed theTamarix aphylla andAlhagi maurorum for Pb,Alhagi maurorum, andSalvadora persica for Cr considered as hyperaccumulator plants. Based on BCF and TF values ofAlhagi maurorum,Tamarix aphylla for Cd, andSalvadora persica for Cr and Pb have the efficiency to uptak...
