Phytoremediation is the use of green plants to decontaminate soils in situ. Soils can become contaminated from activities such as mining & manufacturing. In turn, the copper can be extracted from the plants, known as phytomining. This practical activity investigates the use of hyperaccumulating plants to clean up copper contaminated soils.
