The quality of drinking water is a major public health issue in the context of global climate change. Among emerging contaminants, metal nanoparticles (mNPs) are raising growing concerns due to their unique physicochemical properties and potential health effects. These particles, which result from the degradation of infrastructure (cast iron pipes, metal fittings) or are present in source waters, can carry toxic elements (Pb, Cu, Zn, As) and cross biological barriers. In Paris, public fountains – around 1,200 water points spread across the 20 arrondissements – are an essential infrastructure for access to drinking water, particularly for vulnerable populations and users keen to reduce their consumption of plastic bottles. However, there is no data on the presence of mNPs in these water points, nor on the spatio-temporal variations linked to the four distribution units (UDIs) supplying the capital.
The nanoFONTAINE project aims to:
- Characterise the occurrence, composition and distribution of mNPs (Fe, Cu, Zn, Pb, Ti, Ce, etc.) in Parisian public fountains, in relation to the four UDIs.
- Assess the spatio-temporal variations of these contaminants over a complete seasonal cycle.
- Analyse the perceptions of public fountain users regarding water quality and the potential presence of emerging contaminants.
