﻿Ammonium Nitrogen

The atomic symbol for ammonium is NH4 is an important group containingcompounds that act as nutrients for aquatic plants and animals.Ammonia is found in the form of ammonium. This lets us concentrate on the nitrogen that is in the form of ammonia and ammonium it is commonly called ammonia nitrogen. All plants an animals require nitrogen to rid amino acids and proteins.

**Sources of ammonium**
decaying of plants and animals animal waste industrial waste effluent agricultural runoff Atmospheric nitrogen

High Levels

 * eutrophication**
 * increased algal blooms**
 * increase bod**
 * decreased do**
 * toxic to some organisms**

Low levels

 * limiting factors of plant and algal growth**

Lab Report

**Procedures for collecting Ammonium Nitrogen ** **• **Collect samples in clean plastic or glass bottles. Best results are obtained with immediate analysis. **• **Preserve the samples by reducing the pH to 2 or less with at least 2 mL of Hydrochloric Acid. **• **Store at 4 °C (39 °F) or less. **• **Preserved samples may be stored up to 28 days. **• **Before analysis, warm stored samples to 20–23 °C (68–73.4 °F) and neutralize to pH 7.0 with 5.0 N Sodium Hydroxide.
