Key value for chemical safety assessment

Additional information

The reaction mass of aluminium hydroxide and aluminate nitrate and aluminium sulphate is an inorganic substance. Direct photolysis will not be an important abiotic degradation process.

In air, hydrated aluminum chloride will react with moisture and produce hydrochloric acid and aluminum oxide (Vasiloff, 1991). It is likely that aluminum nitrate and aluminum sulfate will be reacting the same way and form nitric and sulfuric acids, respectively. Since these aluminum salts are usually not emitted to air, the amount of aluminum present in air that is related to the aluminum salts being considered here would be negligible compared with the amount coming from natural erosion of soil (Environment Canada Health Canada, 2000)
