Iron sulfide produces a smell primarily due to the release of hydrogen sulfide (H₂S) gas when it reacts with acids or moisture. Hydrogen sulfide has a characteristic rotten egg odor, which is detectable even at very low concentrations. Additionally, the breakdown of iron sulfide in certain conditions can lead to the formation of various sulfur compounds, which may also contribute to unpleasant odors.
