Description:
This monitoring program was initiated to assess the population exposure to ambient levels of benzene in conjunction with the announcement of benzene as a hazardous material. The program was conducted during the summer and fall of 1977. Average benzene concentrations of 5, 18, and 19 microgram/cu in, respectively, were measured in the widely separated cities of Dallas, Chicago, and Los Angeles. The precision of these data is estimated to be + or - 26 percent of the measured values. The improvement of benzine monitoring and analysis technology was an important secondary objective of this program. However, further research is needed to identify a more favorable collection medium than the Tenex that was used in this study.
