Internal load of aluminum and the central nervous system function of aluminum welders.

Abstract

The S-Al and U-Al measurements indicated increased internal loads of aluminum in most of the welders. This finding is compatible with slowly eliminated aluminum from tissues. The neuropsychological assessment suggested disturbing effects of aluminum on short-term memory, learning, and attention. In the QEEG, a corresponding exposure-effect relationship was found for activity in the frontal region. Further studies are needed on the possibility that exposure to aluminum welding fumes causes harm to human health.
