Bioavailability of mercury in soil and possible phytoremediation strategy
Phytoremediation is an environmentally-friendly and cost-effective technology to clean up heavy metals and the other toxic compounds from contaminated environments. Mercury contamination is ubiquitous in the Y-12 watershed of Oak Ridge, TN and has been identified as a key contaminate in soil, sediment, surface water, and ground water. The objectives of this study were to apply phytoremidiation to mercury contamination in soil and to study the phytoremidiation process, including metal uptake and translocation by chemical analysis, monitoring the changes of plant physiology and spectral reflectance. We have tested two cultivats of Indian mustard (Brassica juncea L.) Czern) cv. Long standing and cv. Florida broadleaf, for their ability to phytoremediate soils contaminated with different forms of mercury (mercuric chloride, nitrate and sulfide). We have found that Indian mustard has a high capacity for uptake and translocation of Hg contaminated soils from Oak Ridge, TN.
