Calcium nitrate, also known as calcium saltpeter or anhydrous calcium nitric acid, is a member of the class of compounds known as alkaline earth metal nitrates. Alkaline earth metal nitrates are inorganic compounds in which the largest oxoanion is nitrate, and in which the heaviest atom not in an oxoanion is an alkaline earth metal. Calcium nitrate can be found in black elderberry, which makes calcium nitrate a potential biomarker for the consumption of this food product. Calcium nitrate is potentially toxic compound. Calcium nitrate, also called Norgessalpeter (Norwegian saltpeter), is an inorganic compound with the formula Ca(NO3)2. This colourless salt absorbs moisture from the air and is commonly found as a tetrahydrate. It is mainly used as a component in fertilizers but has other applications. Nitrocalcite is the name for a mineral which is a hydrated calcium nitrate that forms as an efflorescence where manure contacts concrete or limestone in a dry environment as in stables or caverns. A variety of related salts are known including calcium ammonium nitrate decahydrate and calcium potassium nitrate decahydrate . Methemoglobinemia can be treated with supplemental oxygen and methylene blue 1% solution administered intravenously slowly over five minutes followed by IV flush with normal saline. Methylene blue restores the iron in hemoglobin to its normal (reduced) oxygen-carrying state (L1613) (T3DB).
