| CAS Number | 7782-49-2 | 
|  | CAS number of the metallic form is chosen. Note that this elementary flow is representing also all ions, unless individual elementary flows are differentiated by the to-be-applied LCIA methods, which are then to be preferred. Reference elementary flow of the International Reference Life Cycle Data System (ILCD). |
