Impacts of Nitrogen and Phosphorus Flux

Paper Summary:

This paper presents a research proposal that will confirm that sediments of the small pond discussed in the paper, like larger bodies of water, will contain significant amounts of P and N, and that these sediments will be one of the sources responsible for the increasing incidence of eutrophic or hypereutrophic in the nation's systems of ponds, rivers, lakes and streams.

From the Paper:

"Over the millennia, water has provided humankind with numerous products and services, including transportation, food, drinking water, irrigation, recreation, and protection. Unfortunately, the world's lakes, rivers, and oceans have also been used as a dumping ground for by-products of industrial development and residential refuge. Until recently, however, there was very little attention was paid to water quality (Faeth & Greenhalgh, 2001). Today, the contamination of natural waters such as ponds, lakes, and rivers by anthropogenic organic chemicals has assumed major importance for environmental protectionists. A number of studies over the years have documented how many synthetic organic compounds, although applied or introduced to confined locations, tend to become widely dispersed even to the "ends of the earth" (Schwarzenbach, Haderlein, Muller & Ulrich, 1998). Today, the diffuse loss of phosphorus (P) from agricultural land is generally regarded as a major contributor to eutrophication of fresh water, and there has been a significant increase in research into this issue recently (Fertilizer Applications Influence Phosphorus Runoff, 2004)."
