Which risk increased in early Mesopotamian bronze metallurgy workshops lacking adequate ventilation?

💡 Explanation

Arsenic was a common component in early bronze alloys; the lack of ventilation led to inhalation, causing arsenic poisoning because arsenic vapors were produced during smelting; therefore, this was a major health risk rather than affecting the alloy itself during zinc loss.
