Nitrátszint

Nitrátszint refers to the concentration of nitrate ions (NO3-) in a given sample, most commonly water or soil. Nitrate is an essential nutrient for plant growth, playing a crucial role in the formation of amino acids and proteins. However, elevated levels of nitrate in drinking water can pose health risks. In humans, particularly infants, excessive nitrate intake can lead to methemoglobinemia, a condition where the blood's ability to carry oxygen is reduced. In adults, long-term exposure to high nitrate levels in drinking water has been linked to an increased risk of certain cancers. The primary sources of nitrate in water and soil are the breakdown of organic matter, agricultural fertilizers, and sewage. Agricultural runoff containing fertilizers is a major contributor to nitrate pollution in surface and groundwater. Monitoring nitrátszint is therefore important for assessing water quality, evaluating agricultural practices, and protecting public health. Regulatory bodies often set maximum permissible limits for nitrate concentrations in drinking water to ensure safety.
