This study aimed to identify the indoor air quality characteristics of formaldehyde (HCHO) and total volatile organic compounds (TVOCs) among hazardous substances in living space for military soldiers. To achieve this, we measured and analyzed HCHO and TVOCs, based on the Maintenance and Recommendation Standards designated in Clause 2 of Article 8 (Indoor Air Quality Management at Facilities Required for Military Life) of Enforcement Decree of 「Framework Act on the Status and Service of Soldiers」 Sampling dand Analysis were performed at 37 living spaces for military soldiers. As a result, it was found that the concentration of HCHO and TVOCs at administrative facilities was higher than other places such as education hall, dormitory, restaurant. Therefore it’s necessary to ventilate indoor air more times at Administrative facilities.
