# SUPPLEMENTARY INFORMATION:

## Background 

All biologically active, photochemically reactive, and radiatively active nitrogen compounds in the atmosphere, hydrosphere, and biosphere are collectively referred to as reactive nitrogen. Over the past few decades, human activities leading to the production of reactive nitrogen exceed that of natural terrestrial ecosystem production at the global scale. Reactive nitrogen has both benefited (e.g., increased food production) and impacted health and welfare of people (e.g., respiratory effects) and ecosystems (e.g., biodiversity loss). Scientific information suggests that reactive nitrogen is accumulating in the environment, and that nitrogen cycling through biogeochemical pathways has a variety of consequences. Environmental research suggests that the management of reactive nitrogen should be viewed from a systems perspective and integrated across environmental media. As examples, urban air pollution from reactive nitrogen may contribute to water pollution; and extensive nitrogen loads in river basins may impact downstream coastal zones. Accordingly, linkages between reactive nitrogen induced environmental and human health effects need to be understood in order to optimize reactive nitrogen research and risk management strategies. 

                    The EPA Science Advisory Board (SAB) was established by 42 U.S.C. 4365 to provide independent scientific and technical advice, consultation, and recommendations to the EPA Administrator on the technical bases for EPA policies and regulations. Understanding EPA's various programs for reactive nitrogen is key to developing scientific and technical recommendations regarding the development of an integrated research and management strategies for reactive nitrogen. The SAB has formed the Integrated Nitrogen Research committee to develop information regarding EPA's nitrogen research and risk management programs. The information will provide the basis for an SAB report that will provide advice and recommendations regarding how the Agency may better integrate reactive nitrogen research and risk management strategies across environmental media and programs. Background information on the formation of this expert committee can                           ( print page 1990)                        be found in a                     **Federal Register**                     Notice published March 14, 2005 (70 FR 12476-12477). The purpose of this meeting is for the Committee to: Initiate discussion about the scientific issues underlying the environmental problems due to reactive nitrogen in the environment; learn more about Agency nitrogen research and control strategies; and to plan its future work.
