To evaluate exposure levels of volatile organic compounds (VOCs) in office workers for studies of VOCs exposure in indoor air, personal air sampling was conducted in 22 healthy volunteers in Tachikawa Air Base, Japan Air Self-Defense Force, where no aircraft is operated. Active personal air sampler with activated charcoal tube was used for sampling the VOCs on a day shift. There were 6 straight-chain alkanes with a chain length of C9 to C15 and 4 aromatic hydrocarbons including benzene, toluene, ethylbenzen and o-xylene. Higher VOCs levels of toluene (5.8 - 23.1 ppb) was observed in office workers of library than in other office workers (toluene; 0.2 - 2.5ppb), although exposure levels were below the indoor air quality guideline values of the Japan Ministry of Health, Labour and Welfare. These results suggested office workers in Tachikawa Air Base may be exposed to lower enough VOCs levels to minimize biological effects.
