Objectives: The purpose of this study was to assess the indoor levels of PM10, VOCs and aldehydes in nail shop and hair salon. Methods: The field survey was conducted for 52 hair salons 52 nail shops, and 26 shop-in-shops in Seoul and Daegu city. The field technicians investigated characteristics of each shop including operating time, indoor volume, ventilation and so on. Indoor concentrations of PM10, VOCs and aldehydes, indoor temperature and humidity were measured in 12 hair salons, 12 nail shops and 6 shop-in shops. MP Surveryor II (Graywolf, USA) was used to measure CO₂ concentration, temperature and humidity for 8 hours. PM10 concentrations were measured by minivolume air sampler with Teflon quartz filter (0.2 μm pore size, φ 47 mm, Graseby-Anderson TEF-DISKTM) for 6 hours. VOCs passive sampler (OVM 3500) was used to collect VOCs for 8 hours and analyzed by GC/MSD. Results: The CO₂ concentrations were 759.4±58.2 ppm in nail shops, 731.0±72.5 ppm in hair salons, and 656.4±31.2 ppm in shop-in-shops. The PM10 concentrations were 27.5±14.2 μg/㎥ in nail shops, 33.1±6.3 μg/㎥ in hair salons, and 39.0±26.9 μg/㎥ in shop-in-shops. TVOCs concentrations were 3085.4±1667.8 μg/㎥ in nail shops, 2131.1±617.3 μg/㎥ in hair salons, and 1550.3±529.0 μg/㎥ in shop-in-shops. TVOCs concentrations in nail shops were significantly higher than those in hair salons and shop-in-shops (p=0.002). Formaldehyde concentrations were 60.8±36.6 μg/㎥ in nail shops, 89.1±55.4 μg/㎥ in hair salons, and 45.1±22.5 μg/㎥ in shop-in-shops. Conclusion: TVOCs concentrations in nail shop were the highest among others. TVOC concentrations in all stores exceeded indoor air quality stand of indoor air quality control in public –use facilities, etc act.
