The Walloon biomonitoring project we have been entrusted with involves measuring the presence of pollutants in the human body: endocrine disruptors such as bisphenol A and its alternatives, certain pesticides (such as glyphosate or DDT, currently banned), heavy metals, POPs (Persistent Organic Pollutants)… So many emerging substances found in our environment to which we are all exposed.
Where do these substances come from? They are found in many everyday products (cleaning products, toys, cosmetics, building materials, aerosols, etc.) and in food. They are widely found in the environment, in water, air and soil.
How are we exposed to it? Inhalation, dermal or ingestion.
How are these substances measured in the human body? These substances or their residues (their metabolites) are found in human fluids or tissues (blood, urine, umbilical cord, hair, etc.). By analyzing samples, it is possible to obtain a real, global estimate of people’s exposure to these chemicals. Biomonitoring is therefore particularly useful for monitoring these substances.
At ISSeP, we have been entrusted with a human biomonitoring project to analyze around 1,000 Walloons. The aim is to obtain the very first reference data on Walloon exposure to these substances.
Where do we stand today? Last March, the health crisis forced a halt to sampling. At the end of May, sessions resumed under strict health and safety regulations. Today, recruitment in Wallonia is complete. There were 283 teenagers aged 12-19, 261 adults aged 20-39 and 278 participants in other categories, including newborns. Analyses of these numerous samples are currently underway, and the final results of the study are expected in 2021.eµ
