Arsenic Volatilization
nounPronunciation: /ɑːrˈsenɪk ˌvɒlətɪlaɪˈzeɪʃən/
The process by which arsenic compounds are converted into gaseous forms and released into the atmosphere from contaminated mine sites, particularly under high temperature or microbial activity conditions. This mechanism can redistribute arsenic away from the original contamination site but may create atmospheric dispersion concerns.
Plain English
The conversion of arsenic in soil into gas that rises into the air from abandoned mine sites.
Etymology & History
Usage
"The arsenic volatilization rate at the reclaimed pyrite mine was reduced by 40% through vegetation establishment and soil amendments."
Style guide notes: Specify the arsenic species (AsIII, AsV) and environmental conditions when discussing volatilization mechanisms.

Frequently Asked Questions
What conditions accelerate arsenic volatilization in mines?
High temperatures, oxidizing environments, sulfide oxidation, and certain bacteria increase arsenic conversion to gaseous methylated forms.
How can volatilization be controlled during reclamation?
Water saturation, organic amendments, and vegetation cover reduce volatilization by maintaining reducing conditions and limiting air exposure.
Why Test Candidates on This?
Tested in advanced geochemistry and mine reclamation environmental compliance courses.
