Heavy Metal Stabilization in Soil College of Engineering
heavy metals by plants.!Benefit: Low cost and environmentally friendly.!Disadvantage: length of time for remediation; disposal of harvested heavy metal biowaste. Phytostabilization of mine spoils (chat) in Galena, Kansas. Without revegetation, wind and rain can spread heavy metals beyond initial site of contamination. From Lambert, et al., 1999).
