||The Clean Air Act Amendments of 1990 call for the regulation of numerous toxic chemical species emitted from stationary sources. One of the toxic species is chloroform, an organic compound emitted from paper mills employing the chlorine/chlorine dioxide bleaching process. Two candidate methods were field tested for the collection and analysis of chloroform. Collection efficiencies of a Tedlar bag method and a charcoal adsorbent tube method were compared. Samples from each method were collected from the hypochlorite tower vent (300 ppm chloroform source) of a paper mill bleach plant in South Carolina. Results from a number of laboratory studies and field testing of the methods are discussed. The precision of both methods was found to be acceptable. The bias and precision of the revised charcoal tube method were found to be acceptable per EPA Method 201 specifications. The revised charcoal tube method is recommended for the collection and analysis of chloroform emissions from stationary sources.
