- Environmental chemistry involving both laboratory and field work.
- Water chemistry in surface water is studied to support projects in fisheries and ecological management.
- Projects are in cooperation with several state and federal agencies
Specific projects include the application of inductively coupled plasma/mass spectrometry (ICP/MS) is being studied for the analysis of trace elements in fish otoliths (ear stones) and other materials. Otoliths are aragonitic calcium carbonates crystals that grow continuously during the life of a fish, develop growth annuli (similar to tree rings) that are used for age determination and uptake trace elements from their surroundings. We are developing analytical methodology for freshwater species that are collected from streams and lakes where toxic metals (Hg, Pb, Cr, etc.) have been introduced and laser ablation for direct analysis of solid samples. A second area of research is in the analysis of Endocrine Disrupting Compounds (EDCs) in natural waters. We are beginning the study of methods for the determination of estrogens in stream water in relation to the widespread occurrence of intersex male fish found in the Potomac and other rivers in the mid-Atlantic region. This project will be conducted with the new LC-MS being acquired with NSF grant funds. The third area of research has been application of ion chromatography and other methods for assessment of "acid-rain" impacts. Field data are collected for these studies for several long term projects (>20 years) and are used to help fisheries managers develop mitigation management strategies. Students involved in these projects will collect samples in the National Forests or State Game Lands of Virginia, and return them to the laboratory for analysis. Data thus generated are used to assess the relative impact of acid deposition on water bodies. A fourth area of research is the study of dams and reservoirs and their effects on water quality in otherwise free flowing streams systems. A fifth area of research that is currently beginning is the investigation of the habitat and physical makeup chemistry of the invasive species known as Didymo. Students are expected to learn data interpretation as well as the analytical methodology involved for all the above projects.
