Dear Khan,

You can use a common aquatic weed at your aquatic area to remove heavy metals. You can select aquatic weeds that characteristic by their availability, don't absorb alot of quantity of water and have ability to live at different heavy metals concentrations. Also, You can determine chlorophyll a, b and total chlorophyll to evaluate the healthy of you aquatic weed during removal process and estimate growth rate and tolerance index.

Good luck

Sara
