← HistoryWhich outcome occurred when bronze-age metallurgists smelted arsenical copper ore without proper ventilation?
A)Increased metal hardness via rapid quenching
B)Arsenic poisoning through vapor inhalation✓
C)Accelerated copper corrosion by arsenic ions
D)Reduced smelting temperature using arsenic flux
💡 Explanation
When arsenical copper ore is smelted, arsenic trioxide vaporizes because arsenic has a lower boiling point than copper, and without ventilation, inhalation leads to arsenic poisoning. Therefore arsenic poisoning results, rather than other outcomes due to the specific volatility and toxicity of arsenic compounds.
