Test subjects were continuously exposed to acetic acid vapors which form a constant component of enclosed atmospheres. The inhalation time was 15 to 22 days at concentrations of 5, 10 and 15 mg/m3 or 10 days at a concentration of 26 mg/m3. Physiological parameters showed statistically significant changes at concentrations of 15 and 26 mg/m3. It is suggested that the changes are not adaptive but have been produced by the adverse effect of acetic acid vapors on the human body. It is therefore concluded that the 15 mg/m3 concentration is threshold and the 5 and 10 mg/m3 concentrations are ineffective in terms of the tests used. The most sensitive method is measurement of hydrocarbons (C2-C5), especially ethylene, in the exhaled air.
实验对象持续暴露于乙酸蒸汽中，乙酸蒸汽是封闭环境中的一种恒定成分。在浓度为5、10和15毫克/立方米的情况下，吸入时间为15至22天；在浓度为26毫克/立方米的情况下，吸入时间为10天。生理参数在浓度为15和26毫克/立方米时出现了具有统计学意义的变化。研究表明，这些变化并非适应性变化，而是由乙酸蒸汽对人体的不良影响所导致。因此得出结论，就所采用的测试而言，15毫克/立方米的浓度是阈值，5和10毫克/立方米的浓度没有效果。最敏感的方法是测量呼出空气中的碳氢化合物（C2 - C5），尤其是乙烯。
