These include reduction in lake phosphorus that leads to sufficient reduction in chlorophyll to change the trophic category, to make the lakes 'less eutrophic' or have small or no effect. The factors that determine the actual response are discussed. It is clear that interventions to restore ...
Sources of phosphorus inputs from the atmosphere and their significance to oligotrophic lakes 来自 ResearchGate 喜欢 0 阅读量: 52 作者: TJ Murphy 摘要: Precipitation in the Chicago area was analyzed and found to contain .034 mg/l. of phosphorus with about one half of this present as ...
Domestic wastewater and agricultural activities are important sources of nutrient pollutants such as phosphorus and nitrogen. Upon reaching freshwater, these nutrients can lead to extensive growth of harmful algae, which results in eutrophication. Many C
The International Joint Commission says its science advisory board based the conclusion on an extensive analysis of existing data about the shallowest of the Great Lakes. Excessive phosphorus feeds toxic algae blooms that have plagued Erie in recent years and created a "dead zone" whereoxygen levels...

In eutrophic lakes, ...
of the carbon source required by microorganisms, dissolved organic matter (DOM) plays an important role in freshwater ecosystems. It consists of a wide spectrum of chemical compounds and participates in most of the material circulation (e.g., carbon, nitrogen, and phosphorus) and energy flow in...
Assessing internal and external controls on lake water quality: Limitations on organic carbon-driven alkalinity generation in acidic pit lakes Internal organic carbon generation is limited by the availability of phosphorus; this limitation, together with internal carbon sinks, may be enhanced by the......
Reservoirs (including lakes)play an important role in water supply to cities in China, which accounts for around 40% of supplies from reservoirs. Therefore, water security is one of the biggest challenges for urban water supply. Based on the literature o
although the drawing water is 50% of the total phosphorus input, but the drawing water is 80% of the total amount of water, while the precipitation accounted for 20%, and surface runoff accounted for 39.21% of the total, so the main nutrient source of eutrophication in Sancha Lakes is sur...
The two main external sources of phosphorus to Lake Kinneret are riverine and dust. In accordance with water discharge, the riverine source predominates in winter, while the dust source is more important in the dry season that follows. Isotopic (oxygen) evidence suggests that most of the P in...
