Mel Chin did this with "Revival Field" (Score 5, Informative)

Last term at the University of Oregon, we had the conceptual artist Mel Chin give a lecture on one of his projects entitled "Revival Field".

It's quite similar to what Chris Anderson is doing in Chile and Brazil. Funded by a $10,000 grant from the National Endowment for the Arts (NEA), Revival Field was the first experiment in the United States to use plants to absorb toxic metals from the soil. This launched the nation's burgeoning phytoremediation industry, which one business analyst predicts will be a $400 million dollar business by 2005.
