  • Phytodegradation
• 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
• 6 process of phytoremediation
