“…The concentration of spores and bacteria in natural caves are usually much lower than in the mines. For example, in a Niedźwiedzia Cave in the Sudety moutain, which is often visited by tourists, Ogórek et al (2014a) reported the concentration of spores between 123 and 214 CFU/m 3 , while the most commonly isolated fungi were Cladosporium herbarium and Rhizopus stolonifer. Similar results were obtained by Ogórek et al (2014b) examining the air in an artificial underground complex named Włodarz, located inside the massif of Włodarz, within the Owl Mountains, Lower Silesia, Poland.…”

We determined the species composition and the concentration of colony forming units of airborne bacteria and fungi in a coal mine in Poland. We sampled at six locations in a working shaft at about 500-600 m below ground level. Air samples were collected between 6 and 9 a.m. using the impact method onto Potato Dextrose Agar and TSA. The volume of air filtered for each coalmine sample was 50 L. We found 11 fungal species, with Penicillium meleagrinum and P. notatum as the most common. Six bacterial genera were identified, with Micrococcus spp. as the most common. There were no pathogenic fungi or bacteria identified. The concentration of fungal spores and bacteria in the coal mine air is not a direct hazard to mine workers.

“…In general, the findings revealed a great deal of variation between the mould growth on SDA and PDA. This results relates to the submission of [23,24] that a direct relationship exists between the type of culture media and the species composition of microbes isolated from air. It is further evidenced that the outdoor environment is charged with higher microbial loadings as expected with values of 8.93 × 10 2 and 8.33 × 10 2 CFU/m 3 for SDA and PDA media respectively.…”

Air Handling Units in mechanical ventilation system possess a high degree of potential to circulate contaminants within occupied spaces of a building which often results in sick building syndrome (SBS), building related illness (BRI) and other indoor air quality (IAQ) related issues. This happens despite the expected role of ventilation systems to create a balance of thermal comfort and indoor air quality to the building occupants as well as the stored components. In the hot and humid climate mechanical ventilation systems play an important role of controlling the indoor hygrothermal conditions. Inadequate performance of the mechanical ventilation systems result in several issues ranging from human occupants discomfort, mechanical damages to archival materials and mould problem amongst others. This study presents the measurement and analysis of the mechanical ventilation systems' performance and its effect on various indoor spaces in an academic building in Malaysia. Measurement of airflow, thermal and hygric conditions of the facility together with the aero-biological sampling were executed. The ventilation performance assessment revealed that the AHU fails in its cooling and dehumidification capacities as most of the occupied zones witnessed elevated humidity and low temperature and hence poor hygrothermal performance. On the other hand, results of bio-aerosol assessment indicates that the AHU performs well in its decontamination capacities by reducing the microbial level between the AHU and the occupied zones. The dominant species of mould in the assessed spaces are Penicillium sp., Yeast, Cladosporium sp., and Chaetomium sp. with 100 % occurrence in all the assessed space. On the other hand, Black Mold, Syntalidium sp., and zygomycetes are the least species in spaces with 25 % occurrence. The presence of black mould portends a great danger to the occupants' health and therefore requires urgent attention.

“…Hence, the manuscripts collections (rare books & scholars section) level was selected as the case study in this study. The overall size is 35.33 m × 6.05 m × 3.2 m high (Area = 213.75 m 2 , Volume = 684 m 3 , and A/V ratio = 0.31). Three of the boundary walls are located adjacent to other indoor spaces, hence only one wall is exposed to the external ambient weather with 12 single panel metal window (Fig.…”

“…Despite their ecological importance, mould may be harmful to not only the indoor stored collections but also the occupants' health [2]. The concentrations of outdoor moulds outnumbered that of indoor with the outdoor-indoor route classified as environmental and biological [3]. While the environmental routes include: ventilation systems, cracks, cervices and other openings, water leakage, the biological ones are: animal dander and human transport.…”

Indoor mould contamination portends grave consequence to the stored components as well as inhabitants of infested dwellings. Such defilement, which is due to favourable growth environment for micro-organisms, is often associated with Sick Building Syndrome (SBS) and other Building Related Illness (BRI). As the economic development of Malaysia continues, increase numbers of air-tight, fully air conditioned buildings are evolving. Currently limited guidelines exists on Indoor Air Quality (IAQ) in Malaysia and its knowledge amongst the public is lacking. Hence, diagnosing the aggravating factors favouring indoor mould becomes beneficial as earlier detection is often difficult until growth has advanced. The study aimed at investigating mould infestation in a mechanically ventilated library building in Malaysia. Microclimate parameter and mould sampling were carried out. The microbial investigation results in 72 isolates whose distribution were 86 % mould, 13 % yeast and 1 % bacterial. It is found that Aspegillus sp. and Onychocola sp. were most common. The library internal microclimate distribution is characterised by uneven hygrothermal profile which results in high level of cellulolytic mould species that are highly detrimental to books and other archival materials. It is recommended that the HVAC system operations and set-points be critiqued to bring the ambient to the preservation requirements. In addition, load balancing for thermal and hygric distribution analysis should be executed to eliminate dead-spots in temperature and moisture distributions.
