Nearly 20 years of data from regional USEPA programs specifically designed to meet the congressional assessment requirements of the Clean Air Act CAA and amendments, including long-term, site-specific records and long-term repeat surveys of statistical populations, are presented.

Cost of reactive nitrogen release from human activities to the environment in the United States.
IOP Publishing Ltd. Leakage of reactive nitrogen N from human activities to the environment can cause human health and ecol. Often these harmful effects are not reflected in the costs of food, fuel, and fiber that derive from N use. Spatial analyses of damage costs attributable to source at management relevant scales could inform decisions in areas where anthropogenic N leakage causes harm. We used recently compiled data describing N inputs in the conterminous United States US to assess potential damage costs assocd. We estd.

Nitrogen inputs drive nitrogen concentrations in U. Streams and rivers during summer low flow conditions. Total Environ. Bellmore, R. Elsevier B. Many studies have quantified the relationship between N loads to streams in terms of N mass and N inputs to watersheds; however, N concns.
In this study, we examd. N fixation, and point sources , land cover characteristics, and stream network characteristics, including stream size and the extent of lakes and reservoirs. N concn. Median watershed N inputs were N concns. Land cover characteristics were also important predictors, with wetland cover muting the effect of agricultural N inputs on N concns. In contrast, stream variables showed little correlation with N concns.
This suggests that terrestrial factors that can be managed, such as agricultural N use practices and wetland or riparian areas, control the spatial variability in stream N concns. Sources and transformations of nitrate from streams draining varying land uses: Evidence from dual isotope analysis. American Society of Agronomy. Knowledge of key sources and biogeochem. We applied dual isotope anal. Samples were collected monthly at a range of flow conditions for 15 mo during and analyzed for NO3- concns. Samples from two forested watersheds indicated that NO3- derived from nitrification was dominant at baseflow.

In a mixed land use watershed of large drainage area, none of the source and process patterns obsd. These results emphasize that observations at watersheds of a few to a few hundred km2 may be necessary to adequately quantify the relative roles of various NO3- transport and process patterns that contribute to streamflow in large basins.
