Environmental ethicists and experts in human health have raised concerns about the effects of hydraulic fracking to access natural oil and gas resources found deep in shale rock formations on surrounding ecosystems and communities. In this study, we analyzed the prevalence of discourse on brain and mental health, and ethics, in the peer-reviewed and grey literature in the five-year period between 2016 and 2022. A total of 84 articles met inclusion criteria for analysis. Seventy-six percent (76%) mentioned impacts on brain (...) (e.g., neural tube defects, neurological symptoms), and mental health (e.g., negative psychological effects, stress, depression) briefly; 11 reports dedicated substantive discourse to either or both together. References to safety (77%) dominated the ethics context. Discussion of environmental injustices as fracking sites disproportionately affect vulnerable communities appeared in 38% of the papers. We examine the findings through the lens of environmental neuroethics that brings human-made changes to the environment, brain and mental health, and ethics together into three interwoven lines of inquiry.
