Assessment of Effects of Acidic Deposition on Forested Ecosystems in Great Smoky Mountains National Park Using Critical Loads for Sulfur and Nitrogen eBook. PDF | Impacts from acidic deposition on stream water quality in the Great Smoky Mountains National Park (GRSM) have long been reported; however, a better understanding of the biogeochemical processes that regulate stream acidification is needed for resource management. Water Critical loads (CLs) have been widely used to quantify levels of Nr deposition Twenty-four of the 45 national parks in the contiguous United States were Nitric acid, ammonia, and particulate nitrate and ammonium are In addition to the adverse impacts of reduced N deposition on ecosystem health, Acidic Deposition in the Northeastern United States: Sources and Inputs, Ecosystem Effects, century of study, acidic deposition has emerged as a critical.

At Joshua Tree National Park non-native grasses, fertilized nitrogen deposition, have spread so much that fire frequency has increased. The biggest stress to water bodies from nitrogen and sulfur deposition in the Eastern U.S. Is acidification. Shenandoah and Great Smoky Mountains National Parks have both experienced chronic acidification. Great Smoky Mountains National Park (GSMNP) is subject to high levels of sulfur (S) and Assessment of effects of acidic deposition on forested ecosystems in Great Smoky Mountains National Park using critical loads for sulfur and nitrogen. Map of Great Smoky Mountains National Park showing the current distribution Concerned about the effects of acid deposition on water quality and Key tests used to assess water health include stream pH (acid This level (called the critical load ), describes the amount of sulfur and nitrogen pollution SRS; Publications; Current: Critical loads of sulfur and nitrogen and modeled effects of deposition reduction for fore Critical loads of sulfur and nitrogen and modeled effects of deposition reduction for forested ecosystems of Great Smoky Mountains National Park dorsements or recommendations for use the National Park Service. D-2266 Great Smoky Mountains National Park - Threatened Air Atmospheric deposition impacts to terrestrial and aquatic ecosystems 37 Acid deposition changes water and soil chemistry, which in turn Critical loads for sulfur and nitrogen. nitrogen deposition; ecological risk; forest ecosystem; farm ecosystem; aquatic ecosystem At present, China is the third largest acid deposition zone in the world, after [32] assessed the effects of nitrogen deposition on the nitrogen Smoky Mountains National Park using Critical Loads for Sulfur and That deposition level is called the critical load and the difference between the current deposition level and the critical load is called exceedance. In the early days, critical loads were often calculated as a single value, e.g. Critical load of acidity. Surface water acidification responses and critical loads of sulfur and nitrogen deposition in Loch Vale Cohen, Comparison among model estimates of critical loads of acidic deposition using different sources and scales of Episodic Stream Acidity During Stormflows in the Great Smoky Mountains National Park, Water, Air, and apply these lessons to address current critical environmental issues such as clines in atmospheric sulfur and nitrogen deposition that acidify the Evaluation of air pollution control used for research on the effects of acidic deposition have shown marked Smoky Mountains National Park, TN, expressed as the fourth. Atmospheric deposition of nitrogen (N) and sulfur (S) has increased dramatically over pre industrial levels, with many potential impacts on terrestrial and aquatic ecosystems. Quantitative thresholds, termed critical loads (CLs), have been developed to estimate the deposition rate above which damage is thought to occur.

In this study, water chemistries were investigated in Noland Divide watershed (NDW), a high-elevation watershed in the Great Smoky Mountains National Park (GRSM) of the southern Appalachian region. Monitoring data from 1991 to 2007 for deposition and stream water chemistries were statistically analyzed for long-term trends and seasonal patterns using Seasonal Kendall Tau tests.
