Developing environmentally relevant micro- and nanoplastics to assess removal efficiencies in wastewater treatment processes

Summary

Researchers developed a cheap, reproducible method to produce microplastic and nanoplastic particles that closely mimic what is found in real-world environments, then used these particles to test how well wastewater treatment plants remove them. Having standardized test particles is critical because inconsistent methods across studies have made it hard to compare removal efficiencies and improve treatment technologies.
