Fig. 3 Summary of the results of the lower jaw cartilage and bone density assessments in 10 dpf embryo-larvae exposed to: i) BDP; ii) BUD; iii) FLUT; and iv) PRED for 10 days. Within each panel are shown the following: A) Average lower jaw cartilage fluorescence intensity (Col2a1aBAC:mCherry); B) Average opercle bone fluorescence intensity (sp7:EGFP); C) Average area of lower jaw cartilage; and D) Average area of opercle bone. In all cases, data are shown as the mean ± SEM (n = 16). Data were analysed using Kruskal-Wallis test with Dunn's multiple comparison test and statistically significant values (as compared to SC) are reported by * (P < 0.05), ** (P < 0.01), *** (P < 0.001) and **** (P < 0.0001).
