Children's dietary exposure to metals
Researchers from Edith Cowan University are conducting a study into children’s dietary exposure to metals. The study aims to find out the levels of metals present in children’s diets and the contribution that dietary exposure makes to a child’s total exposure to metals. Of particular interest is the relationship between these dietary metal concentrations and human exposure, in children 5-6 years of age.
Low levels of metals are found in many types of foods. Certain metals (e.g. iron, copper and manganese) form an important part of our normal diet however, an imbalance in our intake of these metals can lead to health problems. Also research is beginning to suggest that for other non-essential metals (for example lead or cadmium), continual levels of exposure may be associated with health effects. At the moment little is known about children’s environmental exposure to metals in Australia, and in particular the contribution that a child’s dietary exposure to metals makes to their overall level of exposure.
Recruitment and data collection for this study is now complete. Analysis of samples is currently underway and results will be available later in 2011. For more information, contact Dr Anna Callan.
