Morphological effects of BHT-COOH exposure to zebrafish larvae at 120 hpf. (A) Control; (B) fishtail deformity (FD) after exposure to 1 mg/L BHT-COOH; (C) intestinal inflammation (IF) after exposure to 1 mg/L BHT-COOH; (D) pericardial edema (PE) after exposure to 5 mg/L BHT-COOH; (E) blood coagulation (BC) and PE after exposure to 5 mg/L BHT-COOH; (F) PE after exposure to 10 mg/L BHT-COOH; (G) PE and BC after exposure to 10 mg/L BHT-COOH. At 5 mg/L, PE was confirmed in five of nine larvae sampled; at 10 mg/L, PE was confirmed in eight of nine larvae. Effects of BHT-COOH exposure on (H) body length and (I) eye size of zebrafish larvae (*p < 0.05, **p < 0.005).
