臭氧毒性及环境卫生标准研究

Studies on ozone toxicity and its environmental health criterion]

The effects of ozone in low concentrations on animals and human beings were studied. The animal observations included biochemical tests, cellular analysis of bronchoalveolar lavage fluid (BALF) and blood, lung morphological observations by TEM and SEM. The human observations included pulmonary function test, behavior function test, etc. Through three years of study certain sensitivity indices and different threshold concentrations of ozone action have been found, and an environmental health criterion for ozone has been proposed, namely, the average concentration in one hour should not exceed 0.1 mg/m3.
