Phytoremediation is the use of plants to clean up contaminated soil, sediment, or water
Heavy metals are metallic elements like lead, mercury, cadmium and arsenic that can be harmful to plants, animals and humans in high amounts
Phytoremediation
1. Plants absorb contaminants from the ground
2. Plants break down organic contaminants
When sunflowers are planted with contaminated soil they absorb these heavy metals through the roots
The need to clean up soil arises when pollutants are present in the environment due to activities like industrial waste disposal, mining or pesticide use
Types of phytoremediation
Phytoextraction - where plants extract toxic substances from the soil
