Fig. 1 Developmental toxicity of La2O3 NPs to zebrafish embryos and larvae. (A) Mortality of zebrafish larvae exposed to La2O3 NPs at 96 hpf. (B) Hatchability of zebrafish larvae exposed to La2O3 NPs at 72 hpf. (C) The body length of zebrafish larvae exposed to La2O3 NPs at 72 hpf. (D) Heart rate of zebrafish larvae exposed to La2O3 NPs at 72 hpf. (E) Liver morphology and size of zebrafish larvae exposed to La2O3 NPs at 120 hpf. (F) Liver area statistics of zebrafish larvae exposed to La2O3 NPs at 120 hpf. Values are expressed as mean ± SEM. Statistical analysis was done by One-way ANOVA and Bonferroni test, compared to the control group, *p < 0.05, * * p < 0.01, * ** p < 0.001.
