The indoor air quality in hotels is an important consideration due to a large workforce engaged in this industry. In this study, the authors characterised volatile organic compounds (VOC) in indoor air of 13 new hotels in southern China, assessing their possible health impact. A 2-day, non-simultaneous sampling was conducted in each hotel. Decorating materials, cleansing agents, and local regional pollutants outside the hotels could contribute to and worsen indoor air quality. Toluene concentrations as high as 498 íg/m3 occurred in a hotel fitted with many plywood products. Highest methylene chloride (34 íg/m3) and total carbonyl (517 íg/m3) concentrations were detected in a hotel where high VOC cleansing agents were used in guest rooms. In an industrial centre hotel, a 102 íg/m3 acetone concentration was observed. The second highest total VOC concentration (445 íg/m3) was detected in a newly renovated hotel. Wooden interior fixtures and wall panels were identified as major VOC and carbonyl sources inside guest rooms.
