The overall aim is to use biomarker data of the menuCH-Kids study to evaluate the distribution of various PFAS, Cd, Pb and As in a population-based sample of Swiss children and adolescents and to identify predictors of exposure.
The specific objectives of this project are:
1. Analysis of serum and/or urine levels (the latter only for As) by participant characteristics, region, dietary and lifestyle factors. Identification of correlations between these foods or food groups and exposure biomarkers of interest.
2. Comparison of the measured internal exposures with the estimated external exposures based on the individual consumption data of the participants from menuCH-Kids and the PFAS data from the VKCS-BLV campaign in animal-derived foods.
3. Comparison of observed biomarker levels with toxicological reference values to assess their risk.
