室内空气臭氧卫生标准的研究

Studies on Hygienic Standard for Ozone in Indoor Air

目的制定我国室内空气臭氧的卫生标准。方法研究了日间臭氧峰值时各类场所室内空气臭氧的水平，并进行了低浓度臭氧的动物实验，观察肺组织脂质过氧化物含量，支气管上皮超微结构及腹腔巨噬细胞吞噬功能。结果验证了空气臭氧水平在０．１ｍｇ／ｍ３的安全性和以此作为室内空气限值的可行性。结论综合国内外现有的资料数据并参考有关标准，提出了室内空气臭氧卫生标准的基准值０．１ｍｇ／ｍ３。

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/m 3 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/m 3 based on the data and relevant criteria at home and abroad.
