  • Algal
  • Harmful algal blooms (HABs) are can be caused by many different types of algae in freshwater ecosystems, and can be triggered by nutrient enrichment. (usgs.gov)
  • EPA, state and local governments, and numerous stakeholders have made progress to reduce nutrients loadings that contribute to harmful algal blooms, hypoxia, fish kills, terrestrial biodiversity changes and degradation of drinking source waters that require costly water treatment. (epa.gov)
  • To help ensure the sustainability of our water, land, and air, and to protect our health while also providing the material, food, and energy required by society, EPA's researchers are exploring solutions to reduce and control nutrient pollution and harmful algal blooms, maximize efficient nutrient usepromote nutrient removal processes, and protect people and natural resources. (epa.gov)
  • It is a primary cause of eutrophication of surface waters, in which excess nutrients, usually nitrogen or phosphorus, stimulate algal growth. (wikipedia.org)
  • In 2010, 18 percent of TMDLs nationwide were related to nutrient levels including organic enrichment/oxygen depletion, noxious plants, algal growth, and ammonia. (wikipedia.org)
  • Algal nutrient solutions are made up of a mixture of chemical salts and water. (wikipedia.org)
  • Ecosystems
  • Nutrient cycling occurs in ecosystems that participate in the "larger biogeochemical cycles of the earth through a system of inputs and outputs. (wikipedia.org)
  • impacts
  • The USGS investigates the source, transport, and fate of nutrients and their impacts on the world around us. (usgs.gov)
  • Innovative solutions have been conceived to deal with nutrient pollution in aquatic systems by altering or enhancing natural processes to shift nutrient effects away from detrimental ecological impacts. (wikipedia.org)
  • optimal
  • At the same time, researchers work to understand the social and economic costs and benefits associated with potential solutions to excess nutrient problems so that optimal solutions for managing water quality over the long term can be achieved. (epa.gov)
  • fruits
  • Fruits, while rich in other essential nutrients, are another poor source of amino acids. (wikipedia.org)
  • Nutrient-dense foods such as fruits and vegetables are the opposite of energy-dense food (also called "empty calorie" food), such as alcohol and foods high in added sugar or processed cereals. (wikipedia.org)
  • Fats
  • Fats are probably the most misunderstood of the nutrients, for they are popularly considered the cause of obesity. (canismajor.com)
  • pollution
  • EPA's research provides innovative solutions to address the problem of nutrient pollution. (epa.gov)
  • Nutrient pollution from some air pollution sources may occur independently of the local land uses, due to long-range transport of air pollutants from distant sources. (wikipedia.org)
  • limits
  • Limits and assumptions should be incorporated when compiling a budget including the average nutrient removal coefficient values if they are not specific to a certain field field. (wikipedia.org)
  • Management
  • For instance, manure fertility analysis, storage practices and other factors will need to be included in a nutrient management plan. (wikipedia.org)
