What the Nitrates Directive is. The Nitrates Directive (91/676/EEC) has been in place since 1991. It aims to protect water quality from pollution by agricultural sources and to promote the use of good farming practice.

What is nitrate directive?
The Nitrates Directive (91/676/EEC) aims to improve water quality by protecting water against pollution caused by nitrates from agricultural sources. In particular, it is about promoting better management of animal manures, chemical nitrogen fertilisers and other nitrogen-containing materials spread onto land.
What is a nitrates Action Plan?
13 Oct 2021, 13.45
The Nitrates Directive (91/676/EEC) has been in place since 1991. ... Ireland's Nitrates Action Programme is designed to prevent pollution of surface waters and ground water from agricultural sources and to protect and improve water quality.
Why are nitrates important?
Nitrates are essential plant nutrients, but in excess amounts they can cause significant water quality problems. Together with phosphorus, nitrates in excess amounts can accelerate eutrophication, causing dramatic increases in aquatic plant growth and changes in the types of plants and animals that live in the stream.
Why are nitrates tested?
A urinalysis, also called a urine test, can detect the presence of nitrites in the urine. Normal urine contains chemicals called nitrates. If bacteria enter the urinary tract, nitrates can turn into different, similarly named chemicals called nitrites. Nitrites in urine may be a sign of a urinary tract infection (UTI).
What is nitrate derogation?
Nitrates Derogation. The Nitrates Derogation allows farmers to exceed the limit of 170 kg of livestock manure nitrogen per hectare set down in the Nitrates Regulations, up to a maximum of 250 kg per hectare, subject to adherence to stricter rules.
Why are there restrictions on the use of nitrates in agriculture?
The purpose of the Regulations is to provide a basic set of measures to ensure the protection of waters, including drinking water sources, against pollution caused by nitrogen and phosphorus from agricultural sources, with the primary emphasis on the management of livestock manures and other fertilisers.
Do nitrates turn into nitrites?
Nitrates and nitrites are compounds consisting of nitrogen and oxygen atoms. Nitrates can turn into nitrites, which can then form either nitric oxide (good) or nitrosamines (bad).
What are nitrates?
Nitrates are naturally found in some vegetables, dairy products and meat. There is no recommendation to limit foods that naturally contain nitrates. Nitrates are also added to processed meats as a preservative. There is strong research that shows a diet high in processed meats increases the risk of colon cancer.
How do nitrates affect the environment?
The environmental impacts of nitrate pollution include ecological and amenity damage to our rivers, lakes and coasts; higher costs, energy use and carbon emissions for drinking water treatment and long-term impacts for our groundwater.
Why are nitrates necessary in a body of water?
Basically, any excess nitrate in the water is a source of fertilizer for aquatic plants and algae. In many cases, the amount of nitrate in the water is what limits how much plants and algae can grow. If there is an excess level of nitrates, plants and algae will grow excessively.
What do nitrates measure?
Nitrates are measured in units of concentration, which are the number of nitrate molecules in a given volume of water. Typical concentrations are usually betweem 10 and 500 parts per million (ppm).
How do nitrate sensors work?
How are they measured? Ammonium and Nitrate ISE sensors operate by measuring the electrical potential of specific ions in water as they move from an area of high concentration to an area of low concentration across a membrane that is designed to allow only a specific ion to cross it.
What does a positive nitrite test indicate?
The presence of nitrites in urine most commonly means there's a bacterial infection in your urinary tract. This is usually called a urinary tract infection (UTI). A UTI can happen anywhere in your urinary tract, including your bladder, ureters, kidneys, and urethra.
How does the nitrate test work?
The nitrate reduction test is based on the detection of nitrite in the medium after incubation with an organism. If present in the medium, nitrite will react with sulfanilic acid (Nitrate reagent A) to form a colorless complex (nitrite-sulfanilic acid).
