Abstract

Exposure to high levels of manganese can cause a form of parkinsonism known as manganism. A higher concentration of MnOOH species on the surface of lapilli from Mount Etna likely results in a high concentration of Mn in groundwater from Etna wells. A possible increased local risk of manganism has been hypothesized. Photograph © Salvatore Giammanco.
