FIGURE 1.

Total distance moved (TDM) of Inland Silverside larvae following 21-day exposure to (A) all the MNP treatments, (B) tire particle treatments, (C) PLA treatments, and (D) polyester MF treatments. TP, tire particle (exposed at 50 p/mL); PLA, polylactic acid (exposed at 50 p/mL); MF, polyester microfiber (exposed at 30 p/mL). W, weathered; particles were weathered under UV A, B, and C light on a shaker at 15 PSU to simulate wave action. Different letters represent statistically significant differences between treatments (p < 0.05, Tukey post-hoc test).
