The process of combining arsenic or arsenic compounds with other substances, or the treatment of material with arsenic.
From 'arsenic' + '-ization' (a suffix indicating a process or conversion), following the productive English pattern of '-ize' verbs and their '-ization' noun forms.
Arsenization is a technical term you'd find in industrial chemistry and materials science—it describes a deliberate chemical process, which is very different from accidental arsenic contamination, though both are deeply concerning!
