Fig. 2From: Matrix Matters: novel insights for the extraction, preparation, and quantitation of microplastics in a freshwater mesocosm studyRepresentative stereoscope microscope images of filters for particle count. Top Row: shows particle count of microplastics per field sample for a PU mesocosm box over five time points. Inlet boxes demonstrate examples of individual particles located on the filter. (MP refers to microplastic). Bottom row: shows the particle count for microplastics in a PP mesocosm box. No extracted microplastics were found for this PP spiked mesocosm box or for the non-spiked mesocosm control box. Fragments of partially-degraded plant matter remainBack to article page
