Microplastic entrainment in surface river algae: a pilot study investigating microplastic concentration during river algae removal

Puntos clave

• Microplastic concentration in river algae appears elevated, indicating a concerning environmental issue.
• The study reports a microplastic concentration of up to 50 particles per liter in sampled river algae.
• Observational analysis across multiple river sites showed algae harvesting procedures influence microplastic levels.
• Findings highlight the need for further investigation into microplastic effects on aquatic ecosystems.
