Fig. 10From: Investigating the correlation between morphological features of microplastics (5–500 µm) and their analytical recoveryPhotomicrographs visualizing the difference between the potential of particle overlap, concealment and agglomeration when (A) A% = 6.3% versus (B) A% = 2.0%. Red rings indicate episodes where smaller particles have agglomerated onto larger particles, thereby causing underestimation of the number of smaller MPs. When the filter is less charged, this is probabilistically less likely to occurBack to article page
