Fig. 2: Prokaryotic content in seawater.
From: Organic additive release from plastic to seawater is lower under deep-sea conditions

Changes in prokaryotic abundance (105 cells mL−1) over time in the presence of polyethylene (PE, squares) and polyvinylchloride (PVC, circles) pellets under surface (a) and deep seawater conditions (b). Controls are seawater incubated with no polymer for 30 days under biotic conditions (crosses).
