Project Number: 1245-12000-040-30
Start Date: Sep 01, 2013
End Date: Nov 19, 2013
Metal contaminated soils from specific contaminated sites of interest to funding Cooperators will be supplied or collected. The soils will be analyzed for total and phytoavailable metals concentrations, pH, organic matter, nutrients, and other factors which might affect fertility or toxicity. Methods to estimate the soluble or phytoavailable fraction of soil metals, or the immediately potentially toxic part of the soil metals will also be applied. After evaluation of the composition, and in consideration of the locality and climate where remediation is to be achieved, and likely remediation amendments available at the location, growth of appropriate plant species will be tested in pot experiments to identify particularly effective remediation amendment combinations. Plant samples and soils conditions after growing plants will be evaluated regarding metal phytoavailability and potential phytotoxicity or deficiencies. In the case of Hg, not only is Hg uptake and toxicity important, but potential emission of Hg vapor will be evaluated.
