Assessing the Potential for Bioremediation through Formation and Fate of Metal Rich Granules in the Terrestrial Environment

Abstract

The purpose of these briefing charts are to investigate potential for bioremediation through MRGs. Background: Previous exposure have shown Pb in MRGs to be biologically unavailable when ingested by predators of terrestrial invertebrates. Experimental Tasks: Generate MRGs through Pb soil exposures and fractionation. Characterize MRG mineral structures through synchrotron analysis. Conduct bacterial microcosm exposures to determine potential for bacterial re-release. Objectives: By inducing invertebrate MRG formation, we will assess: 1) mineral ultrastructure involved in making Pb biologically unavailable. 2) potential for bacteria to release Pb back into the environment in a biologically available form.
