The kidney histological appearance of hibernating lizards after S-metolachlor (SM) and metolachlor oxanilic acid (MO) exposure via soil (HE, 400×). (A,B) represent the male and female kidney in the control groups, respectively; (C,D) represent the male and female kidney in the SM groups, respectively. (E,F) represent the male and female kidney in the MO groups, respectively. The black hollow arrow represents renal epithelial cell necrosis. The yellow arrow represents renal epithelial cell vacuolization. The blue arrow represents interstitial congestion. The green arrow represents renal tubules damage. The circle labels the renal epithelial cell vacuolization and necrosis. The black star represents glomerular necrosis.
