Aquatic pharmaceutical pollution poses ecotoxicological risks to the environment and human health. Consumer pharmaceutical use and disposal behaviors represent a significant source of pharmaceutical compounds in surface waters, and communication strategies are needed to promote pro-environmental behaviors to reduce pharmaceutical pollution. Designing effective risk communication campaigns requires an understanding of public perceptions of aquatic pharmaceutical pollution. The purpose of this mixed-methods pilot study was to test the efficacy of using theories from cognitive linguistics and psychology (conceptual metaphor theory and construal level theory of psychological distance, respectively) in using metaphors in pharmaceutical pollution risk communication. Our methods included a randomized cross-over design in which a convenience sample of university students (n = 20) viewed visual representations of pharmaceutical pollution risks (metaphor based and non-metaphor). We used cognitive interviewing methods to assess metaphor use on participants understanding of pharmaceutical pollution risk, concern about this risk, and willingness to act. Results indicate that participants preferred the metaphorically-framed visual, and that the use of metaphor significantly reduced participants' perceived social and geographic distance of pharmaceutical pollution risk, suggesting a relationship between metaphoric framing and psychological distance warranting additional research. Theoretical and practical implications of metaphor use in risk communications are discussed.
