AI Article Synopsis
- Amending soils with mineral-based materials can help immobilize contaminants, a practice that has been around for decades but is now seeing new methods using various natural and recycled materials.
- These amendments work by trapping contaminants in solid forms, which lowers their chances of entering water or air, thereby reducing health risks for people and wildlife.
- The choice to use mineral amendments in soil treatment is impacted by regulatory standards, societal perceptions, and economic considerations.
Article Abstract
Amending soils with mineral-based materials to immobilize contaminants is both old and new. Although mineral amendments have been used for decades in agriculture, new applications with a variety of natural and reprocessed materials are emerging. By sequestering contaminants in or on solid phases and reducing their ability to partition into water or air, amendments can reduce the risk of exposure to humans or biota. A variety of mineral types are commonly used to amend contaminated soils, with different modes of molecular-scale sequestration. Regulatory, social, and economic factors also influence decisions to employ mineral amendments as a treatment technology.
