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
