- Main aim of cohort
To identify determinants of exposure. To investigate whether pollutants or mixtures of pollutants in the general population are associated with molecular and/or clinical effects. To establish reference values for the general Flemish population for a large set of biomarkers of exposure. Simultaneously, relevant health effects are measured in cord blood/hair or assessed through questionnaires.
Recruited number of:
255 children / 255 mothers / 0 fathers / 0 grand parents / 0 other family members
Approximate proportion of source population included
0
