This research investigates how PFAS “forever chemicals” transfer from fish to their eggs and impact embryonic development. Findings show PFAS increase cellular stress in rainbow trout eggs, potentially affecting survival. Understanding where these chemicals accumulate could inform environmental policy and help protect aquatic ecosystems from long-term generational contamination.

This research shows that antidepressants excreted into wastewater can persist in aquatic environments and alter fish neurobiology, growth, reproduction, stress systems, and behavior. The work argues that antidepressant use carries an environmental cost beyond personal treatment, highlighting the need for better prescribing practices, public awareness, and improved wastewater treatment technologies.
