Abstract

This study was undertaken to compare the performance of three dust samplers for collecting cotton dust fibers. For this study, three dust samplers including Vertical Elutriator (VE), Total Dust Method (TDM) using 37 mm cassette, and the Institute of Occupational Medicine (IOM) sampler were selected. A total of 6 cotton mills and 4 towel factories were investigated. When measured by VE, the GM for cotton dust was 0.19 $mg/m^3$ which was less than the current occupational exposure limit (OEL) 0.2 $mg/m^3$. But when measured by TDM and IOM at the same locations, the GMs were 0.37 and 0.63 $mg/m^3$, respectively. In Korea, most industrial hygienists have used the TDM for cotton dust measurements and the results were compared with either the TLV for cotton dust or the PNOC (particulates not otherwise classified) of 10 $mg/m^3$ for making decisions. The results of this study clearly showed that past cotton dust measurements and decisions made with such results were not correct. It needs to be noticed the related contents by using VE if it applies to the exposure limit, 0.2 $mg/m^3$, and needs to be revised the exposure limit by IOM. Also, if TDM is used, it requires to be studied and suggested to the new OEL.
