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

Heavy metals that are generally contained in industrial waste include lead (Pb), mercury (Hg), cadmium (Cd), arsenicum (As) and chromium (Cr) (Prasasti et al, 2006)
Summary
The biggest source of environmental pollution comes from industrial activity waste. Liquid waste contains dangerous chemicals that can threaten human health and damage the environment and the balance of the ecosystem in it. For human symptoms of heavy metal toxicity can include heart, liver, cancer, disorders and nervous system damage. Heavy metals that are generally contained in industrial waste include lead (Pb), mercury (Hg), cadmium (Cd), arsenicum (As) and chromium (Cr) (Prasasti et al, 2006). Heavy metal contamination in the environment needs to be handled properly to reduce its toxicity. Biological activity is believed to be an alternative method to detoxify polluted environments (Samudro and Mangkoedihardjo, 2020) as well as reduce heavy metal contamination (Dhokpande, 2013)
