Phytoremediation of zinc polluted soil using sunflower (Helianthus annuus L.)

This study aimed at assessing the ability of sunflower to remediate zinc (Zn) impacted soils and partitioning factors Zn in soil-plants interactions. The research method used ex situ experiments using teddy bear seeds with 8 different treatments for each. began preparation sample soil media on garden soil, seeding seeds. was carried out six months starting August - December 2020, Helianthus annuus plants variations Zn. Various concentrations were applied, ranging from 50 ppm 350 ppm. Laboratory analysis Atomic Absorption Spectrophotometry (AAS) method. results have revealed that roots translocate more than shoots, which suggests a phytoremediation mechanism. Sunflower are able Zn, proves it reliable Zn-polluted soil.
