Sorbed versus desorbed PFOS concentrations before (d=0 days) and after (d=4 days) exposure to artificial gut fluid (AGF). Two quantities (0.3 and 1%) of PFOS-spiked PE MPs were applied (sorbed PFOS n=3, desorbed PFOS n=6)
| Exposed PFOS-spiked MPs quantity | Sorbed PFOS onto MPs, d=0 (μgPFOS/mlAGF) | Desorbed PFOS into AGF, d=4 (μgPFOS/mlAGF) | % desorption |
|---|---|---|---|

PFOS PE MPs 0.3% |
0.72 ± 0.08 | 0.55 ± 0.08 | 76.8 |

PFOS PE MPs 1% |
2.40 ± 0.28 | 1.86 ± 0.18 | 77.6 |
