In the determination of organic solvents in workplaces direct reading tube method have been in Korea for decades. But this method is less accurate and couldn't measure TWA (Time Weighted Average) for 8 hours. Authors tried to detect Toluene concentration in S factory by using charcoal tube according to NIOSH method. The concentration was 158.8ppm. We propose this charcoal tube method should be substituted to get accurate results and to protect employee in workplaces related with solvents.
