highly significantp = 0.004
In the present research, MPs were observed in different fish organs, such as the liver, gills, and digestive tract of all five tested species.As mentioned above, the Kruskal–Wallis test for multiple comparisons performed on counted values did not confirm any statistical differences between MP abundance in organs; however, it did show a highly significant difference (H = 10.84; d.f.2, p = 0.004) between MP concentration in organs when percentage contributions were used instead of counted values.
