From: Turning microplastics into nanoplastics through digestive fragmentation by Antarctic krill
Proportions of egested fragmented and whole beads over time. Frequency of whole (blue) and fragmented (orange) particles isolated from faecal pellets of Antarctic krill exposed to Low (20%; n = 3 beakers) (dark) and high (80%; n = 3 beakers) (light) concentrations at: a 24 h on Day 1 (n = 6) and Day 4 (n = 6), b 4 (n = 6) and 24 h (n = 6) on Day 4 only. All faecal material per beaker (containing five krill) was pooled to form a single sample per time point per dose. Letters denote statistically significance differences in the proportion of whole beads excreted over time (p < 0.05, X2 test)
