Project Overview: We investigate the behavior of toxic metals such as arsenic (As), chromium (Cr), lead (Pb), and essential nutrients like phosphorus (P), nitrogen (N), and sulfur (S) in soils. We explore how these elements are bound to soil particles under varying environmental and experimental conditions. Additionally, this work examines how different climatic factors, such as temperature fluctuations, moisture levels, and extreme weather events, influence the interactions and transformations of these metals and nutrients within the soil matrix.
To achieve this, we utilize advanced analytical techniques, including bright light sources at synchrotron facilities, to determine the molecular forms (species) of these metals and nutrients in soils. This molecular-level understanding is crucial for accurately predicting how these contaminants might leach into groundwater or surface water, which in turn affects their toxicity and bioavailability to plants, animals, and humans. By understanding these processes, this research aims to contribute to the development of effective strategies for managing soil contamination and safeguarding environmental and public health.
