Degradation and ecotoxicity of favipiravir and oseltamivir in the presence of microplastics during ozonation and catalytic ozonation of synthetic municipal wastewater effluents
Researchers tested whether ozone-based water treatment could effectively remove antiviral drugs from wastewater, both with and without microplastics present. They found that ozonation removed up to 84% of favipiravir and 64% of oseltamivir, but the presence of microplastics reduced degradation rates by 30-40%. The study suggests that microplastics in wastewater may interfere with advanced treatment processes, making it harder to fully eliminate pharmaceutical contaminants.
