This study investigated indoor air quality (IAQ) at 39 public sites in southern Taiwan including hospitals, schools, office buildings, hypermarkets, libraries, railway stations, theaters, etc. Indoor air quality was preliminarily assessed using handy digital apparatus. Items detected include carbon dioxide (CO 2 ), carbon monoxide (CO), formaldehyde (HCHO), total volatile organic compounds (TVOCs), total bacteria counts (TBC), total fungi counts (TFC), PM 10 , PM 2.5 , ozone (O 3 ) and temperature. Based on the results of walk-through detection, the spatial distribution of indoor air contaminants was further measured over a 24 hour period using the EPA standard method. Major indoor air pollutants were found to include CO 2 , TBC, and TFC. The measured CO 2 concentrations ranged between 438 and 1527 ppm, and only 38.9% of them met the Taiwan EPA suggested threshold of 600 ppm. In the schools and hospitals (Category 1), the measured TFC and TBC concentrations ranged from 62 to TNTC CFU/m 3 and from 196 to 4875 CFU/m 3 , respectively. 33% TFC and 83% TBC concentrations exceeded the suggested threshold, and CO 2 concentrations were moderately correlated with TBC levels. In a case study of hospital bioaerosols, high TBC and TFC levels were effectively lowered through disinfectant housekeeping as well as ClO 2 spray. Three filamentous fungus genera were identified as Cladosporium perangustum, Cladosporium tenuissimum, and Fusarium incarnatum from outdoor samples with high TFC concentrations.

“…A number of studies have been carried out to investigate the level of bioaerosols in indoor residential settings in different geographical regions (Dekoster and Thorne, 1995;Gorny and Dutkiewicz., 2002;Green et al, 2003;Hass et al, 2007;Hunter et al, 1996;Hyvarinen et al, 2001; Kalogerakis et al, 2005;Lee and Jo, 2006;Mentese et al, 2009;Nasir and Colbeck, 2010;Nevalainen et al, 1991;Pastuszka et al, 2000).

The total concentration and size distribution of bioaerosols in three different types of housing (single room in shared accommodation (type I), single bedroom flat in three storey building (type II) and two or three bedroom detached houses (type III)) was assessed during the winter. This research was an extension of a previous study carried out in the summer. The measurement campaign was undertaken in winter 2008 and thirty houses were sampled. Samples were taken from kitchens, living rooms, corridors (only in housing type I) and outdoors with an Anderson 6 stage viable impactor. In housing type I the total geometric mean concentration was highest in the corridor for both bacteria and fungi (3171 CFU/m 3 , 1281 CFU/m 3 ). In type II residences both culturable bacteria and fungi were greatest in the living rooms (3487 CFU/m 3 , 833 CFU/m 3 ). The living rooms in type III residences had largest number of culturable bacteria (1361 CFU/m 3 ) while fungi were highest in kitchens (280 CFU/m 3 ). The concentrations of culturable bacteria and fungi were greater in mouldy houses than non-mouldy houses. A considerable variation was seen in the size distribution of culturable bacteria in type I residences compared to types II and III. For all housing types more than half of culturable bacterial and fungal aerosol were respirable (<4.7μm) and so have the potential to penetrate into lower respiratory system. Considerable variation in concentration and size distribution within different housing types in the same geographical region highlights the impact of differences in design, construction, use and management of residential built environment on bioaerosols levels and consequent varied risk of population exposure to airborne biological agents.

Microorganisms are ubiquitous in the atmosphere but their concentrations are significantly affected by specific environmental factors. Thus, the characterization of bioaerosol levels in both the indoor and outdoor environment have become an important issue due to their adverse health effects. Therefore this study assessed the indoor and outdoor concentrations of bioaerosols and the meteorological conditions in selected salons in four areas of Ibadan North Local Government Area, Oyo State, Nigeria. This comparative cross-sectional study comprised of onsite observations, meteorological measurements viz: temperature and relative humidity (RH) and microbiological assessment (fungi and bacteria load). Building characteristics and sanitary conditions of salons were assessed using a walk-through observational checklist. A TE-10-890 single stage sampler was used for viable bioaerosol sampling and isolates were identified according to standard methods. Data obtained were analysed using descriptive and inferential statistics with SPSS (version 20). Mold growth and damp roof were observed in less than 20% and 40% of salons at the study locations respectively. Mean indoor and outdoor temperature and RH across Agbowo, Mokola, Yemetu and Bashorun were significantly higher than ASHRAE guideline limits. The mean concentrations of bacteria and fungi aerosols were significantly higher indoor than outdoor (p<0.05). Staphylococcus spp, Bacillus spp, Enterobacteria spp and Flavobacterium spp. were the predominant bacteria species isolated while Aspergillus spp, Penicillium spp, Fusarium spp, and Mucor spp. were the most common fungi species detected in the samples. The study showed that both the indoor and outdoor air were contaminated with bacteria and fungi, therefore it is important to control the environmental factors that support microbial growth in order to curtail occurrence of possible adverse effects they may have on health.
