Abstract

Previous papers in this series noted a positive association between aluminum water concentrations and a measure of mental impairment, and anegative association between fluoride concentrations and the same measure of mental impairment. The results obtained were qualitatively similar to the corresponding associations obtained from death certificatedata that list Alzheimer's disease as the underlying cause of death. In addition, the results were also qualitatively similar to the results obtained in a number of other studies carried out at different times, in different areas and using different outcome measures for the measure of mental impairment. The present study concerns the role of iron concentrations and specifically, whether when taking iron concentrations into account, the previously noted associations involving aluminum are maintained. The results show that this seems to be the case and also suggest that iron can compete with aluminum, and can both increase or decrease the likelihood of showing signs of mental impairment. The results do not indicate consistently that by modifying the methods of water purification, using iron instead of aluminum, the treated water will be less biotoxic, although there could be instances, particularlywhen the aluminum concentrations are relatively high, when the use ofiron compounds is beneficial.
