Air Quality Related Values (Aqrvs) For Northern Great Plains Network (Ngpn) Parks, Effects From Ozone; Visibility Reducing Particles; And Atmospheric Deposition Of Acids, Nutrients And Toxics, Timothy J. Sullivan

United States National Park Service: Publications

Summary

This report describes the Air Quality Related Values (AQRVs) of the Northern Great Plains Network (NGPN). AQRVs are those resources sensitive to air quality and include streams, lakes, soils, vegetation, fish and wildlife, and visibility. This report also describes air pollutant emissions and air quality in NGPN, and their effects on AQRVs. The primary pollutants likely to affect AQRVs include nitrogen (N) and sulfur (S) compounds (nitrate [NO₃^-], ammonium [NH₄⁺], and sulfate [SO₄^2-]); ground-level ozone (O₃); haze-causing particles; and airborne toxics.

The 13 parks that are included in …

Northern Great Plains Network (NGPN)

National maps of atmospheric N emissions and deposition are provided in Maps A and B as context for subsequent network data presentations. Map A shows county level emissions of total N for the year 2002. Map B shows total N deposition, again for the year 2002.

There are three parks in the Northern Great Plains Network that are larger than 100 square miles: Badlands (BADL), Missouri (MNRR), and Theodore Roosevelt (THRO). In addition, there are 10 other smaller parks.

Total annual N emissions, by county, are shown in Map C for lands in and surrounding …
