Is it safe to drink water with high nitrates?

How much nitrate is toxic to humans?
Acute Toxic Effects Human lethal doses of 4ā50 g (equivalent to 67ā833 mg kgā1 body weight) have been reported. Toxic doses range from 2 to 5 g (RIVM, 1989, WHO, 2011) of NO3.

We are still learning about the health effects of nitrate. Nitrate can turn hemoglobin (the protein in blood that carries oxygen) into methemoglobin . High levels can turn skin to a bluish or gray color and cause more serious health effects like weakness, excess heart rate, fatigue, and dizziness.
What does nitrate do to your body?
Nitrate performs physiological functions in various systemic activities, including blood pressure reduction, platelet aggregation inhibition, and vessel protective effect – functions similar to those of NO [3, 37].
What are the signs of nitrate poisoning?
Signs of acute nitrate toxicity are a result of severe inhibition of oxygen transfer and are strikingly obvious. Symptoms include bluish color of mucous membranes, rapid and difficult breathing, a rapid pulse (>150 beats/minute), tremors, staggering, collapse, and death.
How do nitrates affect your body?
These nitrites in the blood cause changes in hemoglobin, or the molecules that help move oxygen in the body. Nitrates can make it so that less oxygen is available for the body to function properly.
What are the symptoms of nitrate poisoning?
Can nitrates make you sick?
Nitrates are relatively inert, which means they’re stable and unlikely to change and cause harm. However, bacteria in the mouth or enzymes in the body can convert them into nitrites, and these may be harmful. In turn, nitrites can either turn into: nitric oxide, which is beneficial for the body.
