Occurrence And Fate Of Microplastics In Urban Freshwater Systems

2023
Marziye Mola Zadeh

Summary

Microplastics were found in urban freshwater pond sediments at highly variable concentrations, with buoyant particles dominating by mass and water mixing playing a key role in distributing plastic particles through the water column.

Study Type Environmental

MP content in the pond sediments varied up to two orders of magnitude.• Buoyant MPs made up 95.4 % of the MPmass and 83.5 % of the MP-number.• No trend in the spatial distribution of MPsneither concentration, size, nor polymer • Mixing is an important factor for transporting buoyant MPs to the pond sediments.• Sediment contents of silt and organic matter correlate with the MP-distribution.
