Fig 2. Concentrations and polymeric composition of floating plastic debris in relation to the distance from land in the Mediterranean Sea.

Pie charts show the polymeric composition for the three water strips, <1 km (194 items analyzed), 1–10 km (113 items), and >10 km from land (99 items analyzed). Plastic fragments’s abundances (lower graph) includes measurements made during this study in the western Mediterranean (green circles) and data reported by Lucia et al. (blue circles; [17]) and Cózar et al. (red circles; [15]).
