Analysis of Vinyl Chloride Personal Monitor Samoles
The carbon tube personal monitor samples which arrived on August 2, 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 101. Please state that number in any inquiry about them.
The attached 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 8hour time ^weighted average values. Any inquiries about the sampling details of carbon tube exposures will be referred to you.
The ppm values were calculated on the assumption that all the sampling times were 10 min. and therefore the volumes were 10 liters. This assumption may have been false.
It is our estimate that vinyl chloride detected at 0. 01 mg is reliable to + 50%. For vinyl chloride detected at 0. 1 mg the value is good to_^5%.
