Atmospheric carbon disulfide concentrations in the working place and the amount of carbon disulfide inhaled during the normal work were estimated so that the relation between the industrial environment and the exposure to it was assessed. The former was determined by the diethylamine copper acetate method with fritted filter glass sampling tubes, and the latter by recovering absorbed carbon disulfide from the active carbon filter of a mask which was worn by workers during their normal work at a normal breathing flow rate. It was experimentally verified that the absorbed carbon disulfide was recovered almost hundred precent by extraction under the condition of hot water vapor pressure. In the field survey of viscose rayon factories, it was found that the recovered value well corresponded with the environmental concentration in the breathing zone and that there was the feasibility of utilization of such a mask in the industrial hygiene practice.
