Soil Chemistry–Environmental Quality Research Nexis
Dr. Bruce James is the PI. Research in soil chemistry has focused on oxidation-reduction (electron transfer) processes in the vadose zone and at the interface of soils and groundwater. It comprises two main goals: to understand the energetics and accuracy of analytical methods for electron activity associated with abiotic and biotic processes; and to apply knowledge of redox processes to the remediation of soils contaminated with heavy metals, biosolids, excess nitrogen, and metalloids. Current research focuses on remediation of chromate-contaminated soils due to industrial waste disposal practices during the last century or more. The research is aimed at clarifying and explaining electron shuttle mechanisms for natural organic matter and other reducing agents for chromate. Future studies will examine microbial and chemical processes, with particular emphasis on improving our understanding of electron activity and its role in soil-plant relations and groundwater protection.
