Persistent Chemicals, Persistent Activism: Scientific Opportunity Structures and Social Movement Organizing on Contamination by Per-and Polyfluoroalkyl Substances.

Engagement with science is a prominent feature for many social movements, yet the dimensions of that scientific engagement and bidirectional relationships between science and advocacy are incompletely theorized in social movement scholarship. While social movement scholarship has previously demonstrated the importance of external political and economic factors for social movement processes and efficacy, we show that the emergence and success of environmental health activism is also dependent on dynamic relationships between scientific evidence and lay demands for particular types of knowledge production and application. Despite decades of industrial production and widespread contamination, per- and polyfluoroalkyl substances (PFAS) were a politically obscure class of chemicals until a recent spike in attention from activist, regulatory, and scientific circles. Drawing from in-depth interviews with activists of PFAS-impacted communities, we develop the scientific opportunity concept to examine how activists create and mobilize scientific factors to support their goals, and how scientific factors, in turn, support the emergence of further activism. Dimensions of scientific opportunity include availability of funding streams, openness and receptivity of institutionalized scientific spaces, presence of collaborative or community-led research, methodological and technological advancements aligned with activist demands, availability of relevant scientific findings and datasets, and presence of prominent scientific allies. We conclude by discussing the relevance of our concept to a wide range of social movements addressing science and technology.
