| Abstract |
The relationship between internal aluminium loads and central nervous system function was studied in 65 aluminium welders and 25 current mild steel welders in Finland. Body burden was estimated, and the aluminium concentrations in serum (S-Al) and urine (U-Al) were analysed. Central nervous system functions were assessed with a neuropsychological test battery, symptom and mood questionnaires, electroencephalography (EEG) and P3 event-related potentials. Subjective symptoms showed exposure-related increases in fatigue, mild depression, and memory and concentration problems. Neuropsychological testing revealed a limited effect, mainly in tasks demanding complex attention. The visual EEG analysis revealed pathological findings only for aluminium welders. The study indicates that the body burden threshold for adverse effect approximates an U-Al value of 4-6µmol/L and an S-Al value of 0.25-0.35µmol/L. |
