In addition, methemoglobin clogs the vessels of the microcirculatory bed, causing hypoxia at the cellular level. If its concentration in the blood increases to 50-60%, death occurs.
Excess nitrates in water also provoke the development of gastrointestinal dysfunction and food poisoning.
Chronic poisoning with nitrogen compounds can cause stomach or pancreatic cancer.
Because of their ability to react
The main symptoms of nitrate poisoning are weakness, vomiting, anemia, cyanosis of the skin, and often czechia businesses directory diarrhea.
