From: Proposal for an initial screening method for identifying microplastics in marine sediments

Microplastics (MP) from the sediment samples were stained and visually observed (fractions 1–6) unaided and using a microscope (fractions 2–6). (A) fraction 1, particles > 2 mm, photographed using an anα5100 Sony camera, (B) fraction 2, particle size 0.85–2 mm, (C) fraction 3, particle size 0.42–0.85 mm, (D) fraction 4, particle size 0.25–0.42 mm, (E) fraction 5, particle size 0.106–0.25 mm, and (F) fraction 6, particle size < 0.106 mm.
