Nitrates used in agricultural fertilizers may leak into the ground and may contaminate well water. The current EPA standard of 10 ppm nitrate-nitrogen for drinking water is specifically set to protect infants. [13] Benzocaine applied to the gums or throat (as commonly used in baby teething gels, or sore throat lozenges) can cause methemoglobinemia.
For example, nitrate levels are subject to monitoring to comply with drinking water quality standards in the United States and other countries. [ 24 ] [ 25 ] The link between blue baby syndrome and nitrates in drinking water is widely accepted, but as of 2006 some studies indicated that other contaminants or dietary nitrate sources, might also ...

Most side effects are direct consequences of the vasodilation and the resultant low blood pressure. They include headache ("nitrate headache") resulting from the widening of blood vessels in the brain, reflex tachycardia (fast heart rate), flush, dizziness, nausea and vomiting. These effects usually subside after a few days if the treatment is ...
In the NO − 3 anion, the oxidation state of the central nitrogen atom is V (+5). This corresponds to the highest possible oxidation number of nitrogen. Nitrate is a potentially powerful oxidizer as evidenced by its explosive behaviour at high temperature when it is detonated in ammonium nitrate (NH 4 NO 3), or black powder, ignited by the shock wave of a primary explosive.
In organic chemistry, peroxyacyl nitrates (also known as Acyl peroxy nitrates, APN or PANs) are powerful respiratory and eye irritants present in photochemical smog. They are nitrates produced in the thermal equilibrium between organic peroxy radicals by the gas -phase oxidation of a variety of volatile organic compounds (VOCs), or by aldehydes ...
The combination of table salt with nitrates or nitrites, called curing salt, is often dyed pink to distinguish it from table salt. [6] Neither table salt nor any of the nitrites or nitrates commonly used in curing (e.g., sodium nitrate [NaNO 3], [7] sodium nitrite, [7] and potassium nitrate [8]) is naturally pink.
