Pharmaceuticals in Waterways and Their Impact
Pharmaceuticals are increasingly found in waterways, with over 900 different ingredients detected globally. These substances often enter the water through human waste, as not all medications are absorbed by our bodies and can end up in sewage systems. Additionally, runoff from pharmaceutical manufacturing contributes to this pollution. The presence of these drugs raises concerns about their long-term effects on aquatic life, making it essential for researchers to investigate how such substances alter the behavior of fish and other marine organisms.
