Nitrátnitrogén
Nitrátnitrogén refers to nitrogen in the form of nitrate (NO3-). It is a crucial nutrient for plant growth and is a key component of fertilizers. Plants absorb nitrate from the soil through their roots. While essential for life, excessive amounts of nitrate in the environment can lead to several problems. In aquatic ecosystems, nitrate is a common pollutant. High concentrations can cause eutrophication, a process where excessive nutrient enrichment leads to algal blooms. These blooms can deplete dissolved oxygen in the water when they decompose, harming fish and other aquatic organisms. In drinking water, high nitrate levels can pose a health risk, particularly to infants, as it can interfere with the blood's ability to carry oxygen, leading to a condition called methemoglobinemia or "blue baby syndrome." Sources of nitrate pollution include agricultural runoff containing fertilizers and animal waste, as well as wastewater treatment plant discharges and septic system leakage. Monitoring and managing nitrate levels in both water and soil are important for environmental and public health.
