Abstract
|
|
|
Through field comparison of Tenax/Heat method and Charcoal/CS_2 for workers exposed to Methyl isobuthyl ketone(MIBK), toluene, and cellosolve acetate in the paint spray processes, a study was conducted provide basic data for the evaluation of organic solvents in the workplace.
The limits of detection(LOD) of Tenax/Heat method showed 1/83.4, 1/125, 1/156.5 in Methyl isobouthyl ketone(MIBK), toluene, and cellosolve acetate in comparison to those of Charcoal/CS_2, respectively. The exposure levels of the three organic solvents using Tenax/Heat method were very significantly higher than those using Charcoal/CS_2 (p＜0.01). It was shown that the exposure levels of the three organic solvents had very significant difference between two methods in less than 1.0 ppm of exposure level(p＜0.01), while the exposure levels of toluene and cellosolve acetate didn´t show significant difference in more than 1.0 ppm (p＞0.05). In the estimation of exposure levels for not-detected samples, the two monitoring methods had the highest correlation when estimated values through equation were used.
