    Abstract:
    OBJECTIVE: To formulate a national hygienic standard for ozone in indoor air. METHODS: Indoor air ozone concentrations at variety of places were detected at its peak level in the daytime. Also, animal experiments exposed to low-level ozone were conducted to study the contents of lipid peroxide in the lungs, the ultrastructure of the bronchial epithelium and the phagocyte function of peritoneal macrophage. RESULTS: Safety of ozone concentration of 0.1 mg/m3 in indoor air and feasibility to use it as hygienic standard were tested and proved. CONCLUSION: The national hygienic standard for ozone in indoor air is recommended at 0.1 mg/m3 based on the data and relevant criteria at home and abroad.
