[Dynamics of acid-base equilibrium of the blood in humans a long-term exposure to an atmosphere containing acetic acid vapors].

Two experimental series, each of 20 days in duration, were carried out using 8 healthy test subjects, aged 25 to 44 years. The purpose of the experiments was to identify the effect of two different concentrations of acetic acid vapors in an enclosed environment on blood acid-base equilibrium and gases. In both experimental series ambient temperature was increased to 33 degrees C during the last three days of exposure in order to better evaluate the acetic acid vapor effect. The most significant changes in acid-base equilibrium were detected when the vapor concentration amounted to 25 mg/m3.
