Abnormal lipid deposition was increased in the liver with long exposure to NMPs. (A) Representative images of Oil Red O for livers with H2O treatment, 80 nm, 0.5 µm and 5 µm NMPs exposure. Scale bar, 50 µm for 200 magnification and 20 µm for 400 magnifications. (B) Quantification of Oil Red O positive area. (C) Representative images of TEM for livers with H2O treatment, 80 nm, 0.5 µm, and 5 µm NMPs exposure.
