Abstract:

The National Exposure Research Laboratory's Ecosystems Research Division in Athens, GA, conducts research on organic and inorganic chemicals, greenhouse gas biogeochemical cycles, and land use perturbations that create direct and indirect, chemical and non-chemical stressor exposures and potential risks to humans and ecosystems.

          Comprehensive models based on fundamental studies of stressor behavior are developed to predict exposures in multimedia environments, to simulate the interactions of the climate system and the terrestrial biosphere, and to evaluate the aggregate causes of ecological stress, including land use change/management, within a watershed/regional context.

          Field and laboratory experiments are conducted to quantify and model greenhouse gas fluxes between the atmosphere and the terrestrial biosphere and to understand abiotic and biotic pollutant fate processes in soils, sediments, and water. ERD-Athens develops, tests, applies, and provides technical support for exposure and ecosystem response models used for assessing and managing stressor risks to humans and ecosystems that are state-of-the-art and produce estimates of known uncertainty.

          Major modeling emphases are: earth systems models for evaluating and minimizing/managing the global and regional risks from climate and land use changes; ecosystem response models for evaluating and minimizing/managing the exposures and risks from multiple stressors within watersheds; and exposure models for evaluating the multimedia fate of chemicals. The models incorporate ease of use features such as geographical information systems, automated parameterization, output visualization, and automated uncertainty analysis. Assistance and support are provided to model users.
