Title Longitudinal study on potential neurotoxic effects of aluminium: I. Assessment of exposure and neurobehavioural performance of Al welders in the train and truck construction industry over 4 years
Bibliographic information Oct. 2007, Vol.81, No.1, p.41-67. Illus. 57 ref.
Abstract This study examined the reliability of aluminium biomonitoring as indicator of individual long-term exposure, together with long-term changes of neurobehavioural performance among aluminium welders in relation to exposure. Data on aluminium exposure neurological behaviour were obtained over a period of four years from a group of aluminium welders and an unexposed age-matched control group. The measurements of exposure included total dust in air as well as aluminium in pre-shift and post-shift plasma and urine samples. Neurobehavioural methods comprised symptoms, verbal intelligence, logic thinking, psychomotor behaviour, memory and attention. Computer-aided tests from the Motor Performance Series (MLS) and the European Neurobehavioural Evaluation System (EURO-NES) were used. Data were examined with regression analysis. The aluminium welders who had been working in this profession for an average of 15 years showed no significantly increased symptom levels compared with the control group. Statistical analyses revealed neither a correlation between biomonitoring and performance variables nor a significant difference between exposed and control groups.
