Abstract for presentation at 14th IUAPPA World Congress

Due to the importance of indoor air quality, the Indoor Air Quality Management Group of Hong Kong Environmental Protection Department had published a document “A Guide On Indoor Air Quality Certification Scheme For Offices And Publics Places”. This scheme is suitable for offices and public places with mechanical ventilation and air conditioning systems. The indoor air quality objective was set on this document. According to this scheme, a two-level IAQ objective (excellent class and good class) was used as a scale to assess the air quality of those offices and public places.
This paper describes research carried out which has investigated the variation in pollutants in a typical Hong Kong shopping mall over a week period.
The aim of the investigation was to study the daily variation of indoor pollutants in a typical shopping mall and to find the relationship between those pollutants. Bacteria, fungi, carbon dioxide (CO₂),total volatile organic compound (TVOC), individual volatile organic compounds (VOCs), respirable suspended particulate (RSP), carbon monoxide (CO), nitrogen dioxide (NO₂),ozone (O₃), radon(Rn), formaldehyde (CH₂O),relative humidity, temperature and air movement were measured in this study. Afterwards, the data was compared with the objective mentioned on the previous paragraph. Respirable suspended particulate, air movement, nitrogen dioxide and total volatile organic compounds exceeded the excellent class of the Indoor Air Quality Objective.
