F. 3, 1974 Analysis of Viqyl Chloride Personal Monitor Samples JUl 1 8 iy/4 RESEARCH LIBRARY The carbon tube personal monitor samples which arrived on June 11, 1974 have been analyzed. Corporate Environmental Services Lab has measured each amount of adsorbed vinyl chloride. These samples have been given a log number of 26 . Please state that number in any inquiry about them. The following table gives the results of the analyses. The ppm values are based on the specific air volume sampled. The results have not been extrapolated to 8-hour time-weighted average values. Any inquiries about the sampling details of carbon tube exposure will be referred to you.
