From Phyto-Remediation to Phyto-Mining: Maximizing Value in Producing Bio-diesel from Pennycress.

A series of pennycress seeds were germinated hydroponically in solutions spiked with varying amounts of lead (II) nitrate. Uptake of the lead into roots and stalks of the plants were examined via Energy Dispersive X-Ray Fluorescence (EDXRF). Results and findings show promise for larger scale use of this phyto-remediation technique and the use of EDXRF to quantify it. Additionally, a plant sample provided by The Power Alternative (TPA) was examined by EDXRF for the presence of lead in the stalk material.
