Notes on other potential health effects and hazards:
- Upon inhalation, iron is an irritant to the lungs and gastrointestinal tract (ILO 1998).
- The settling of iron particles in the eye results in siderosis. The extent of siderosis is affected by the location of the deposition. Deposition in the cornea results in a "rust ring" surrounding the area, which is associated with discomfort, hyperemia of the conjunctiva, and the influx of inflammatory cells (Grant 1986).
- Iron dust may induce interstitial lung disease (Chu et al. 2011).
