Which risk increases when ancient Mesopotamian bronze sickle blades are repeatedly used to harvest reeds in brackish water?

💡 Explanation

When bronze sickles contact brackish water repeatedly, chloride ions in the water induce pitting corrosion via electrochemical reactions concentrating at defects. Therefore pitting corrosion susceptibility increases, rather than biofouling, work hardening or tensile strength reduction, which involve unrelated mechanisms and metallurgical conditions.
