| Abstract: |
This article discusses the issues associated with sediment and colloid transfer and runoff from intensively farmed grasslands into streams. The authors discuss the relationship between organic matter in grasslands and nutrient runoff such as phosphorus which leads to eutrophication. They argue that persistent organic pollutants frequently adhere to organic sediments while microorganisms can carry pathogens harmful to humans. Soil erosion can also cause siltation of streams and rivers which can impact fish and other freshwater aquatic biota. They define key issues as analytical challenges, inadequate inventories, underestimating the role of organic matter problems with difficulties in modeling and integration. |
