  2. Ammonia pollution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_pollution

    Ammonia in salt water ecosystems will have similar effects on fish as ammonia in freshwater ecosystems. Another aquatic animal that is affected by increasing amounts of ammonia is coral. Coral are very important for diversity in oceans and increasing concentrations of ammonia in the water is harming the bacteria that are found on the coral. [27]

  3. Freshwater environmental quality parameters - Wikipedia

    en.wikipedia.org/wiki/Freshwater_environmental...

    The toxicity of ammonia is dependent on both pH and temperature and an added complexity is the buffering effect of the blood/water interface across the gill membrane which masks any additional toxicity over about pH 8.0. The management of river chemistry to avoid ecological damage is particularly difficult in the case of ammonia as a wide range ...

  4. Ammonia solution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_solution

    Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −

  5. Anaerobic lagoon - Wikipedia

    en.wikipedia.org/wiki/Anaerobic_lagoon

    Anaerobic lagoons have been shown to harbor and emit substances which can cause adverse environmental and health effects. These substances are emitted through two main pathways: gas emissions and lagoon overflow. Gas emissions are continuous (though the amount may vary based on the season) and are a product of the manure slurry.

  6. Nutrient pollution - Wikipedia

    en.wikipedia.org/wiki/Nutrient_pollution

    Nutrient trading is a type of water quality trading, a market-based policy instrument used to improve or maintain water quality. The concept of water quality trading is based on the fact that different pollution sources in a watershed can face very different costs to control the same pollutant. [30]

  7. Analysis of water chemistry - Wikipedia

    en.wikipedia.org/wiki/Analysis_of_water_chemistry

    Water chemistry analysis is often the groundwork of studies of water quality, pollution, hydrology and geothermal waters. Analytical methods routinely used can detect and measure all the natural elements and their inorganic compounds and a very wide range of organic chemical species using methods such as gas chromatography and mass spectrometry .

  8. Recirculating aquaculture system - Wikipedia

    en.wikipedia.org/wiki/Recirculating_aquaculture...

    Water is pumped through the filter, and ammonia is utilized by the bacteria for energy. In recirculating systems, daily water exchanges are commonly used to control nitrogen levels. Stable environmental conditions and regular maintenance are required to ensure the biofilter is operating efficiently. [citation needed]

  9. Water quality - Wikipedia

    en.wikipedia.org/wiki/Water_quality

    The National Water Quality Inventory Report to Congress is a general report on water quality, providing overall information about the number of miles of streams and rivers and their aggregate condition. [65] The CWA requires states to adopt standards for each of the possible designated uses that they assign to their waters.
