The overall objective of this targeted human biomonitoring is to objectivise the exposure to PFAS of people living in the study areas.
The levels of PFAS impregnation measured in the residents of the Chièvres, Ronquières and ZIP areas will be compared with the levels measured in the general Walloon population, in order to determine whether there is an overexposure to PFAS in the residents of areas affected by water or environmental contamination.
Initially, this study will focus on areas where residents were supplied at some time with water containing PFAS concentrations in excess of the future standard of 100 ng/L. Initially, these will be the streets supplied by the Chièvres and Ronquières wells.
