Phytoremediation for Soil Cleanup

Quick fact

The Tibetan pennycress (Thlaspi caerulescens) can accumulate up to 30,000 parts per million of zinc in its leaves without dying—over 300 times the level toxic to most plants.

Why this is interesting

What if the solution to polluted soil was as simple as planting a garden? Some plants can absorb toxic metals and break down oil spills—turning a cleanup project into a living, growing system.
