- 2014 April 21, “Subtle effects”, in The Economist, volume 411, number 8884:
- Manganism has been known about since the 19th century, when miners exposed to ores containing manganese, a silvery metal, began to totter, slur their speech and behave like someone inebriated. The poisoning was irreversible, and soon ended in psychosis and death. Nowadays workers are exposed to far lower doses and manganism is rare.
