What does nitrite do to the 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.
How much nitrite is too much?
Under certain conditions, even relatively low nitrite levels of 0.25 mg/l may be enough to weaken sensitive species. Anything above 0.1 mg/l should be viewed as unacceptable and a potential cause of stress, although some fish might tolerate very high levels.
How does sodium nitrite kill you?

What happens if nitrate levels are too high?
High nitrate levels are especially harmful to fry and young fish and will negatively affect their growth. Furthermore, the same conditions that cause elevated nitrate often cause decreased oxygen levels, which further stress the fish.
How do I bring my nitrite levels down?
First, perform water changes with dechlorinated water to reduce the nitrite level. The addition of a half-ounce (1 tablespoon) of salt per gallon of water will prevent methemoglobin toxicity by blocking the nitrite absorption through the fish’s gills. Any aquarium salt or marine salt mix can be used.
Can humans get nitrate poisoning?
People can become nitrite-poisoned in many different ways. Misuse or excessive use of any medicine or product containing nitrates, whether unintentionally or intentionally, can lead to poisoning. Poisoning can result from swallowing, inhaling, or even skin contact.

How do I lower the nitrate levels in my fish tank?
Water changes: Performing regular water changes with water that has little or no nitrate will lower the overall nitrate level in the aquarium. If your local tap or well water is high in nitrate, using deionized water (DI) or reverse osmosis water (RO) can help keep nitrate levels low when doing a water change.
How do you remove nitrates from your body?
Eat a diet high in antioxidants. Vitamin C and certain other vitamins can reduce the conversion of nitrates and nitrites to nitrosamines.
Is 40 ppm nitrate too high?
