Potential health effects

Chronic exposure to high concentrations of iron have been associated with hemosiderosis, hemochromatosis and in sever cases, liver cirrhosis. Typical occupational exposures to iron compounds are not expected to cause these effects. Chronic inhalation can produce “mottling" of the lungs (siderosis). This is considered a benign pneumoconiosis and does not normally lead to fibrosis or cause significant physiologic impairment. Inorganic phosphates have been studied extensively due to their use as food additives. The JECFA (Joint FAO/WHO expert committee on food additives) determined that the acceptable dietary intake for humans would be 0 to 70 mg/kg. These doses and route of exposure are not considered relevant to occupationa) settings. Pre-Existing Medical Conditions: None known.

Environmental effects

May release phosphates which will result in algae growth, increased turbidity, and depleted oxygen (This comment directed primarily to fresh and coastal water systems).
