Phytoremediation of hydrocarbon-contaminated soil
ACS National Meeting, Anaheim, CA, March 22, 1999

Abstract (Paper 40)::
Phytoremediation, the use of plants for remediation of contaminated soil, has potential as a less expensive, less destructive, and more aesthetically pleasing alternative to traditional soil remediation techniques. The remediation of an aged refinery soil with and without plants was followed in a field study and in a greenhouse study under saturated and unsaturated soil conditions. Results show significant reduction in hydrocarbon contaminants in all soil treatments (planted or unplanted) over time. Levels of contaminants were significantly lower in soil associated with plant roots than in bulk soil, suggesting a potential role for plants in soil remediation.
