#arseniferous
- Arsenical — Containing arsenic in its chemical structure, relating to arsenic, or derived directly from the compounds of this metalloid. In industrial and medical terms, it describes minerals, thermal mineral waters, industrial waste, or old pharmaceutical preparations that have variable proportions of arsenic in their composition, requiring special protective measures due to cumulative toxicity risks.
- Arseniferous — Containing or bearing arsenic in its structural composition; said of ores, rocks, geological strata, or groundwater in which arsenic is present as a stable chemical component or as a significant metallic impurity. The identification of arseniferous deposits is crucial in economic geology and environmental risk assessment, as processing these materials can release toxic substances into the surrounding environment.
