title: [Field tests of a new passive personal monitor for organic vapors].
abstract: The method making use of a New Du Pont PRO-TEKTM G-AA Organic Vapor Air Monitoring Badge, was applied to evaluate the concentration of organic vapor in a working atmosphere. Other methods such as the direct air sampling method and the method of adsorption on charcoal tube were compared with the above mentioned method. In the comparative study of these methods in working places, similar results were obtained by the new badge method and the charcoal tube method, though different results were obtained between the direct air sampling method and the mentioned two methods. The differences may have resulted from the period needed for the sampling, that is, an intermittent sampling was generally used for the direct sampling method. In a study of personal exposure monitoring by the badge method and the tube method, the results obtained by the badge method were lower than those obtained by the latter method suggesting the effects of the response of the badge on organic vapor in working places. The relationships between the instantaneous changes of the concentration of organic vapor in the atmosphere and the response time of the badge will be discussed elsewhere.
