Whatever the actions may be, it is proved that a nitrite is capable of very effectively inhibiting cavitation damage in a cooling system. However, nitrites often produce harmful nitrosoamine by reacting with an amine salt or salts in coolant, which is a carcinogenic substance. Since no other effective cavitation damage inhibitors were known, antifreeze/coolant concentrates containing a "substantial" amount of nitrite have continually been used in coolant, though their use is not altogether advisable from the foregoing point of view.
