Abstract
Purpose: To collect data on indoor air quality (IAQ) and environmental hygiene in subdivided units (SDUs). Methodologies: Forty-one questionnaires and environmental assessments were conducted from July to September 2013. Twenty of them were spot checked with IAQ parameters. Airborne microbial diversity was analysed. Allergens, endotoxins and glucans in settled dusts were measured in 8 SDUs. Results: Questionnaire results indicated IAQ and hygiene problems. Temperature and relative humidity were the worst performed IAQ parameters, while most SDUs reached Good Class in CO, total VOCs and PM10 levels. Some units had high microbial counts and endotoxin and glucan levels, and showed regional microbial disparity. Discussion: Biological pollution is a concern in SDUs and linked to building, occupant and environmental factors. Conclusions: This study gives some insights into the conditions of SDUs and the unique research needs in this environment.
