What is the importance of nitrates?

Nitrate (NO3-) is composed of the elements oxygen and nitrogen, and is an important source of nitrogen for plant and animal life; but too much nitrate in drinking water can be harmful to human health.

Why is it important to test for nitrates in water?

Excess nitrate in water is a cause of eutrophication, which is when excessive nutrients get into water bodies, causing excessive plant growth. This large amount of plant growth effectively steals oxygen from the water, causing fish and other aquatic life to die. This is why a nitrate test in water is crucial.

What impact does the presence of nitrates have on water quality?

Nitrates have the same effect on aquatic plant growth as phosphates and thus the same negative effect on water quality. The plants and algae are stimulated, which provide food for fish. This may cause an increase in the fish population.

Where is nitrite used?

These additives function as preservatives in food and they are both used extensively to enhance the colour and extend the shelf life of processed meats. Nitrite is considered the active curing ingredient responsible for the preservation of the food in combination with other ingredients, like salt.
