Uses/Function

• "…have long been used in the preservation of meat…Sodium nitrite and sodium nitrate are reduced to NO by compounds in the meat..Nitrates and nitrites also prevent the growth of bacterium that causes botulism, a dangerous and sometimes fatal form of food poisoning. However, concern has arisen about the possibility of a reaction between nitrite ion and certain organic compounds in the mear or in the digestive system to form nitrosamines, which are cancer-casuing compounds." 1

• "a nitrogen fertilizer" 2
