Chemical Formula • NOз-
Acceptable Ranges of Nitrates in Nature • The acceptable range in freshwater is about 1 ppm. Anything over 3 ppm can be dangerous.
Sources of Nitrates from Nature or Pollution • Possible sources include surface runoff from agricultural or landscaped areas, the use of excess nitrate fertilizer and is often a byproduct of septic systems.
Problems Caused by Excess or Lack of Nitrates in a Water System • Excess of nitrates may cause algae blooms, water anoxia, dead fish, dead zones, eutrofication and in humans can cause blue baby syndrome, death and can change hemoglobin to methemoglobin. • If not enough nitrate is present, plants will not be able to grow.
Ways to Alleviate any Imbalance of Nitrates in a Water System • Ways include increasing plant density
What is the Purpose of Nitrogen Fixing Bacteria? • Recycle nitrogen in an ecosystem • These bacteria take nitrates in the soil and convert them into nitrogen, which is usable by plants.
