To formulate a national hygienic standard for ozone in indoor air.
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.
Safety of ozone concentration of 0.1 mg/m3 in indoor air and feasibility to use it as hygienic standard were tested and proved.
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.
