Exposure to manganese from water and food products - associated health risks

Purpose and goal

The objective of this project is to assess the public health impact of various forms of exposure to manganese (Mn), in particular to infants, through the synergistic utilization of expertise provided by the collaborating institutes. We also aim to establish a platform for researcher and student mobility.

Results and expected effects

This project will contribute to improving the health-based data base for Mn exposure, providing an overall understanding of exposure pathways from source to subject. It will thereby contribute to improved risk assessments for infant exposure, in particular. It will also result in an exchange of staff and students between the collaborating institutions in both research and teaching. The project will also contribute to textbooks in Medical Geology and disseminate findings to the public through appropriate authorities in Sweden and in Australia.

Approach and implementation

Data on Mn exposure from main sources in Western Australia (WA) and Sweden will be reviewed to identify geographic areas with elevated exposure. Thereafter, patterns of neurological disease and exposure in a WA town will be assessed using epidemiological and geochemical data. The findings will be used in further evaluation of Mn exposures in Sweden. An assessment of direct infant Mn exposure through water and infant food will be incorporated into existing research at KI on the impact on infant development from Mn in drinking water. In addition, a course will be developed to tie together the excellence from both institutes and to provide an arena for researcher, teacher and student mobility.
