David Long does research and teaching in the areas of Aqueous and Environmental Geochemistry.  He has been: studying the biogeochemical cycles and interactions of elements (including trace and heavy metals) and dissolved organic compounds in surface environments (e.g., wetlands, rivers, lakes, groundwater); working to understand both the natural and human induced changes in water chemistry as it moves through the water cycle using stable isotopes, multivariate statistics, and geochemical modeling; quantifying the influences of human activities on environmental systems using sediment chronologies; and relating knowledge learned from the above studies to evaluate the influences of the environment on human health through exposure analysis.
