| Abstract: | The ultra-structural changes of Monopterus albus liver cells were observed with transmission electron microscopy after sublethal exposure to Cu2+ and nonionic surfactant AE(linear alkylethoxylate). The results showed that, in polluted environment with Cu2+ of 4. 5 mg/L, the nucleus of M. albus liver cells was deformed, chromatins were condensed, endoplasmic veticulum was vesiculate, and many lysosomes and peroxisomes were found in cytoplasm; in polluted environment with surfactant AE of 4.0 mg/L, the nucleus of M. albus liver cells was deformed, endoplasmic veticulum was linear, the volume and number of lysosomes and peroxisomes were larger, and vacancies appeared and even death occurred in some cytoplasms and cells.
