Salicornia europea, a Bioaccumulator in Maharloo Salt Lake Region

T. Eslamzadeh

Osmotic potential, percent of ash, mineral salt content and heavy metals of the halophyte Salicornia europea, collected from Maharloo region, Shiraz, were determined. Sodium content in ash was found to be up to 30%, equivalent to 31500 μg g-1 dry matter. The high sodium content of the plant especially in the shoot as compared with normal content of 10 μg g-1 in non-halophytes suggests that the plant can be considered as a sodium hyperaccumulator and it can be used as a means of phytoremediation for saline media, including soil and water. The content of mineral nutrients K, Mg, Ca, Zn and Cu were also determined and were compared with the normal amounts needed for plant growth. The results indicate that mobile elements such as Na, K and Mg are mostly transported to the shoot, where, they may be compartmentalized in the leaf cell vacuoles; whereas the immobile elements such as Ca, Cu, Zn and Fe are mainly retained in the root. The amount of Mg in the shoot and also the amounts of copper and iron in the root are much higher than the normal amount found in other plants; indicating that the root tissues of the plant can be further studied to be used as biosorbent for heavy metal contaminants in wastewater and soil. The amounts of heavy metals such as Ni, Cr, Cd, Pb and Hg were also determined. The results indicate that the amounts of these heavy metals are relatively high in this plant.
