We investigate simultaneously the risk of contamination of these environments by silver and the process of the social and political construction of this risk by water managers, health authorities, agencies and committees responsible for expert evaluations, environmental associations, and potential users of silver or nano-silver. Four updated models of risk construction allow us to understand the logic of arguments mobilized at this stage of the emerging risk. This interdisciplinary cooperation opens up possibilities for dealing with some environmental health issues; it highlights the benefits of an approach aiming to disseminate knowledge to enable action and to promote awareness and analysis by the local stakeholders and officials who face this emerging problem.
