Demographic evaluation of the fertility of aluminium industry workers: influence of exposure to heat and static magnetic fields.
A demographic analysis of the fertility of French aluminium industry workers was performed in order to evaluate the potential effects on male fertility of occupational exposure to heat and static magnetic fields occurring in certain workshops. Two groups of aluminium workers were studied: one group of 692 potroom workers exposed to heat and to static magnetic fields, and a control group of 588 workers from the same plants, who had not been exposed to these factors. The birthrate was significantly higher in the 'exposed' group than in the 'control' group. The relative birthrate ratio ('exposed' versus 'control') was 1.1 (P < 0.001). These results do not show any decrease in the fertility of potroom workers exposed to heat and static magnetic fields, when compared to other workers in the aluminium producing industry.
