Policy Assessment for the Review of the Secondary National Ambient Air Quality Standards for Oxides of Nitrogen and Oxides of Sulfur, January 14, 2011 Version - Appendices

摘要

The goal of this Task was to determine the relative degree of protection offered by aquatic versus terrestrial critical acid loads within a landscape. Critical acid loads for lakes and streams within watersheds of the Adirondacks and Shenandoah Valley were compared against terrestrial critical loads calculated for same watersheds to determine which estimate had the lowest, most protective critical load for acidifying nitrogen and sulfur deposition.
