Abstract

The Cosmet’eau project (2015–2018) investigates the changes in the personal care product (PCP) consumption practices: from whistle-blowers to impacts on aquatic environments. In this project, the example of PCPs will be used to understand how public health concerns related to micropollutants can be addressed by public authorities—including local authorities, industries, and consumers. The project aims to characterize the possible changes in PCP consumption practices and to evaluate the impact of their implementation on aquatic contamination. Our goals are to study the whistle-blowers, the risk perception of consumers linked with their practices, and the contamination in parabens and their substitutes, triclosan, and triclocarban from wastewater to surface water. The project investigates the following potential solutions: modifications of industrial formulation or changes in consumption practices. The final purpose is to provide policy instruments for local authorities aiming at building effective strategies to fight against micropollutants in receiving waters.

1. Scientific issues and projet presentation

The substances used in the formulation of most personal care products (PCPs) are found ubiquitously in surface waters worldwide. Among them, parabens (PBs), triclosan (TCS), and triclocarban (TCC) are widely used in the composition of PCPs, pharmaceuticals, and other consumer products as antiseptic or conservative. These substances are of increasing concern due to their wide utilization and potential negative effect on aquatic ecosystems as endocrine disruptors or induction of antibiotic resistance Besides, these substances are interesting for social science studies since their fate are linked to whistle-blowers. In France, parabens have been the subject of a specific alert. In 2005, the French TV program «Envoyé Spécial» revealed being a key moment in the alert process, reporting a suspected link between parabens and breast cancers by scientists (Dardre et al., 2004). This alert led to the emergence of paraben free or organic products and to changes both in the industry and consumer practices. Two findings emerged from these observations:

  • (i) the changes in practices were led by industries without any formal regulations and
  • (ii) few questions were raised by the public authorities and consumers on the safety of substitutes.

For both environmental and health issues, there is a need of a better understanding of the fate of these substances in the urban cycle and of their harmful effects. Moreover, we need to understand the different steps leading to citizen and elected representative awareness and actions to regulate the diffusion of micropollutants.

2. Objectives

  • The first objective is to study whistle-blowers and their influence on consumer and government awareness and responses.
  • The second objective is to develop innovative technical and sociological tools for monitoring both consumption practices and levels of contamination.
  • The third objective is to monitor the levels of contamination from wastewater up to surface waters, and their evolution due to changes in practices.

  • The fourth objective is to understand the motivation of people changing their practices.

  • And finally, we want to propose innovations in governance: toward the changes in consumption practices that could be encouraged by the (local) authorities in order to reduce the source of micropollutants.

3. Organisation and agenda

Multidisciplinary approach to study the micropollutants and the actors that can reduce their emission at source: geography, social sciences, politic sciences, chemistry, ecotoxicology.

5. Financial support

The Cosmet’eau project has been funded within the framework of a French call for project about “Micropollutants: innovation and changes of practices” launched by the French Ministry of Environment, The French National Agency for Biodiversity (AFB), and a French water agency (Agence de l’Eau Seine-Normandie).
