Pretreatment Methods for Further Analysis of Microplastics in Wastewater and Sludge Samples

Summary

Wastewater and sludge samples require careful pretreatment to remove organic matter and other interfering materials before microplastic analysis can yield accurate results, and the choice of pretreatment method significantly affects particle recovery and identification. Standardizing pretreatment protocols is critical because wastewater treatment plants are major pathways through which microplastics reach both aquatic environments and agricultural soils via sludge application.

Study Type Environmental

Wastewater treatment plants (WWTPs) are a significant source of microplastics (MPs) in both aquatic and terrestrial environments. Since WWTPs cannot retain the MPs completely, a fraction of these particles can reach rivers and oceans. Moreover, due to the high...
