Which outcome resulted when ancient Mesopotamian copper smelters excessively increased charcoal fuel without increased ventilation?

💡 Explanation

When charcoal is burned with insufficient oxygen, incomplete combustion occurs, producing carbon monoxide because of limiting oxidation processes, increasing poisonous emissions. Therefore carbon monoxide poisoning risk increases, rather than increased efficiency, lowered viscosity, or faster dehydration, which depend on different reaction conditions and fuel-air mixtures.
