Risks of nanos in water

The marketing and use of manufactured nanomaterials has increased considerably since the early 2000s in many fields: cosmetics, textiles, household appliances, sports equipment, glass and construction materials, cars, aeronautics, boats, food, etc.

More and more nanomaterials, nanoparticles or nanoparticle residues are present in water (from wastewater, some continue on to the treatment plants, then into rivers and streams). With what consequences for the aquatic fauna and flora? What about the microorganisms in the soil on which the sludge from the wastewater treatment plant is spread? Concerns are emerging among a growing number of stakeholders. Who is doing what on these different aspects?
On all these questions, only scattered information is available today, often difficult to understand for the non-specialist or addressing only a particular aspect without giving an overall vision.

Therefore, this dossier initiated in 2015 gathers the available information as well as the issues that arise today and could become a problem if no action is taken by the various institutions involved.

It is a base that we wish to complete and update according to the evolution of knowledge: your contributions are welcome!

Upcoming Nano Agenda

Managing the risks associated with nanomaterials (CEA, Grenoble)
  • Awareness-raising aimed at personnel in contact with nanomaterials during research, formulation, production, maintenance, cleaning, upkeep, etc., as well as safety coordinators or engineers, facility managers, heads of laboratories where nanoparticles are handled.
  • Organizers: INSTN Grenoble (CEA)
  • On the agenda: potential impact on health; metrology and protection; control of potential risks associated with nanomaterials; consideration of societal aspects.
