acid-volatile sulfide

initialism: AVS
https://doi.org/10.1351/goldbook.14420
Soil- and sediment-associated solid-phase sulfides extractable with cold hydrochloric acid.
Note: AVS may be chemically available by acid extraction without being bioavailable. Thus, AVS can reduce metal toxicity by binding metals in anoxic soils or sediments, thereby rendering them unavailable to most living organisms.
