Wild sunflower (Helianthus annuus) is investigated for its ability to remediate a Pb-contaminated soil. Using a sandy loam soil with pH of 7.67, wild sunflower is observed to clean up as much as 29.1 percent and 27.8 percent Pb at contamination levels of 60 ppm and 160 ppm, respectively, with reference to the non-vegetated control. At those two levels of initial Pb concentration, shoots harvested after nine weeks are found to accumulate corresponding averages of 0.36 percent and 0.43 percent Pb on a dry weight basis.
