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.

Heavy metals in drinking water pose serious health risks, yet current testing methods often require laboratories or lack accuracy. This research develops optical sensors called optodes that use light-responsive dyes to detect contaminants. The goal is a portable, real-time device capable of accurately measuring heavy metals like lead in water.
