We have been asked to provide information about the acute and chronic effects of exposure to iron, carbon manganese, and silicon dusts. To determine the health effects from such materials, it would be necessary to know more about the nature and extent of one’s exposure. However, we can provide some general information.
1. Iron can cause health effects after ingestion or inhalation. I will restrict my comments to the inhalation effects. In very high doses iron may cause acute lung inflammation. Chronic exposure can lead to chest x-ray abnormalities but typically doesn’t affect lung function, so called “benign pneumoconiosis,” or “siderosis.”
2. With regard to carbon manganese, I think the questioner is referring to a chemical known as manganese carbonate. This substance may cause acute lung inflammation at very high doses. Chronic exposure to elevated levels can have effects on the nervous system leading to a variety of psychiatric and motor/movement complaints.
3. Silicon dusts can be irritating to mucous membranes (eyes, nose, throat, and windpipe) at high concentrations. In general, silicon dust exposure isn’t associated with any long-term health effects.
If more information is required we recommend you contact an industrial hygienist in your area. In addition, more information is available on the Internet through TOXNET, a service of the National Institutes of Health. The web address is http://toxnet.nlm.nih.gov/
Thank you for the question, we hope you find this information useful.

Long term you could be looking at pulmonary fibrosis.
