Hair manganese and hyperactive behaviors: pilot study of school-age children exposed through tap water.
BACKGROUND Neurotoxic effects are known to occur with inhalation of manganese particulates, but very few data are available on exposure to Mn in water. We undertook a pilot study in a community inExpand

Long-term exposure to "low levels" of manganese oxides and neurofunctional changes in ferroalloy workers.
Occupational exposure to manganese can cause early neurobehavioral effects in low- or a-symptomatic workers. A battery of neuropsychological tests was administered to a group of 61 ferroalloy maleExpand
