Fig. 2 shows that, during Altiratinib 1st half year to the 2nd half year of the experiment period, ΣPAH concentrations in grass carp, bighead carp and mud carp reared in experimental fish ponds increased (p < 0.05), accompanied with significant increases of 4-ring and 5,6-ring PAH ratio in ΣPAHs (p < 0.05). However, 2, 3-ring PAHs were still most abundant in the fish 'Altiratinib' collected in the 2nd half year of the experiment (except bighead carp fed with control diet).
