A Review on Heavy Metals (As, Pb, and Hg) Uptake by Plants ...

Metal uptake by plants depends on the bioavailability of the metal in the water phase, which in turn depends on the retention time of the metal, as well as the interaction with other elements and substances in the water. Furthermore, when metals have been bound to the soil, the pH, redox potential, and organic matter content will all affect the ...

Heavy Metals and Aquatic Environments | Science Project

Some water plants can remove contaminating heavy metals from aquatic environments. Others are poisoned by them. Do an experiment comparing different species of aquatic plants for this ability. Use a copper test kit to test the water each day after the plants have been added. We used copper sulfate because it is highly soluble.
