Reactive Nitrogen in the United States: An Analysis of Inputs, Flows, Consequences, and Management Options
This is a report of the EPA Science Advisory Board, which has conducted a study to analyze sources and fate of Nr in the United States and provide advice to EPA on integrated nitrogen research and control strategies. The objectives for this study were to:

  • Identify and analyze from a scientific perspective the problems Nr presents in the environment and the links among them;
  • Evaluate the contribution an integrated nitrogen management strategy could make to environmental protection;
  • Identify additional risk management options for EP A’s consideration; and
  • Make recommendations to EP A concerning improvements in nitrogen research to support risk reduction.

The SAB report provides findings and recommendations addressing these study objectives.
