Fig. 9From: Investigating the correlation between morphological features of microplastics (5–500 µm) and their analytical recoveryHistograms visualizing the MP distribution within specified size groups, following each individual transfer. legends refer to the filter area occupied by particles (A%). Size distribution of MPs remains relatively stable following four successive transfers, yet SMPs display an increase in the smallest size fraction with decreasing A%. As a general trend, this tendency was not observed in FMPs and may therefore be linked to excessive A%, leading to increased probability of particle agglomeration and concealmentBack to article page
