Soil Contaminants

Soil contaminants are harmful substances introduced into the soil from sources like industrial activity, waste disposal, chemicals, or spills. These pollutants—such as heavy metals, pesticides, or petroleum products—can degrade soil health, harm plants, and pose risks to humans and animals through contact or food chain contamination. They may persist in the environment, making cleaning difficult, and can lead to decreased land usability. Understanding and managing soil contaminants is essential to protect environmental quality, ensure safe agriculture, and maintain healthy ecosystems.
