Evaluating environmental health communication: The readability of factsheets about per- and polyfluoroalkyl substances (PFAS)

This study demonstrates that PFAS factsheets are typically not written at an appropriate reading level. We identify several areas for improvement such as using health literacy tools to reduce the complexity of language, incorporating infographics and pop out boxes, and providing concise summaries of information. To increase environmental health literacy, environmental health communicators should draw on the learnings of health communication and utilise existing tools to improve readability.
