There are many ways of measuring nitrogen forms. Total nitrogen can be determined by adding chemicals to convert all of the nitrogen forms in a sample to nitrate, and then measuring nitrate concentration. Nitrate and nitrite can be measured together or separately. Nitrate and nitrite are most often measured using a colorimetric method, which means the color of treated sample reflects the concentration of the ...

    Proximity to the river has a direct impact on how much of the nitrogen actually makes its way into the water body.

  • Environmental Hazards and Human Health

    Human activites artificially enrich water bodies with nitrogen and phosphorous, resulting in unnaturally high rates of plant production, accumulation of organic matter, both of which degrade water and habitat quality (Cloern, 2007).

  • Air and Water Pollutants

    When wastes which are high on nutrient content are discharged in water they cause excessive growth of algae and weed which in turn cause the water to become unfit for drinking.

  • Excretion of nitrogen

    Fish can excrete nitrogen directly as ammonia, as the ammonia dissolves in water very quickly. Terrestrial animals generally need to conserve water, so they excrete nitrogen in way that does not require large amounts of water.
