Abstract
Two studies were performed which were designed to determine whether coconut carbon could be used in the field to determine the levels of styrene (100425) in the breath accurately. In the first, serial samples of environmental air, exhaled air, and blood were collected from two subjects in a factory where styrene was used in the manufacture of reinforced fiber glass products. The subjects were exposed to styrene for 4 hours. The second study determined the relationship between the concentration of styrene in the mixed exhaled air, as measured with the new method, and the concentration of styrene in the end exhaled air (alveolar air) measured with a portable gas chromatography. Samples were obtained from 27 workers at a factory where fiber glass boats were manufactured. The results of the study indicated that the measurement of mixed exhaled air should be suitable for predicting either the uptake of or exposure to styrene over the ranges of concentrations typically encountered in the workplace. The authors state that the precision of this method represents the combined random errors from all sources related to the collection and analysis of the samples. This method can easily be extended to other organic solvents which are stable on activated carbon.
