Bioavailable nitrogen has been falling in the rain since the industrial revolution. It exists in the ecosystem as a limiting nutrient for plants and animals. Concentrated nitrogen in surface and groundwater can have deleterious effects such as eutrophication, algae blooms, and hypoxia.
Nitrogen exists in several compounds in the ecosystem, those being, NO3, NH4, NO2, DON, TN, etc. Atmospheric deposition has resulted in the low-level exposure to nitrate (NO3-) by terrestrial and aquatic ecosystems.
This course will provide the reader with studies that have shown the results of low-level exposure to nitrogen on ecosystems. Several study sites will be evaluated under controlled experiments. The controlled sites were 40 x 40-m plots with varying degrees of fertilizer and mammal manipulation.
This course material is based on the document “Ecosystem Stress from Chronic Exposure to Low-Levels of Nitrate,” as published on the website of the United States Environmental Protection Agency.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
