“…Some fungi can cause allergy-mediated diseases (Karbowska-Bernet et al, 2007) and mycotoxicosis in human (Flanningan, 2001). Aspergillus, Mucor and Rhizopus pose threat to vulnerable individuals (Soleimani et al, 2013). Aspergillus fumigatus, A. flavus and Stachybotrys chartarum should not be present in the air of library and their concentrations should be zero CFU/m 3 (Górny et al, 2004 andAugustynska et al, 2010).…”

ACTERIAL and fungal contamination in the air and settled dust .... were studied in old and new book libraries located in the National Research Center (NRC), Dokki, Giza, Egypt. The investigated libraries differ in age, design, size, ventilation type, and a number of occupants in relation to microclimatic parameters and particulate matter (PM) load. Airborne microorganisms were collected using an Andersen two stage impactor sampler. Indoor airborne bacteria and fungi ranged from 0-1060.4 CFU/m 3 and 11.8-315.6 CFU/m 3 , respectively. Outdoor airborne bacteria and fungi ranged within 11.7-2514.7 CFU/m 3 and 0-713.7 CFU/m 3 , respectively. Bacteria and fungi associated surface settled. The dust ranged from 0.4-10x10 6 CFU/gm and 0-73x10 4 CFU/gm, respectively. Fine microbial fraction (particles ≤ 8 μm in size) constituted 2-24.94% and 68.35-94.15% of the total airborne bacterial and fungal concentrations, respectively. Indoor/outdoor (I/O) ratios of airborne microorganisms were less than 1 at both libraries, indicating no indoor microbial sources. Gram positive cocci (14.3-47%) and bacilli (52.9-85.7%) were the dominant bacterial isolates in the air state, while bacilli represented 100% of the total isolates in the surface settled dust. Bacillus pseudomycoides and B. subtilis dominated indoors while B. subtilis and Staphylococcus outdoors. Aspergillus and Penicillium, were the common fungal species in both libraries under investigation. Many of the isolated fungal taxa had enzymatic activities (lipase, protease and cellulase), with A. flavus, Curvularia pallescens, Fusarium oxysporium, P. notatum and Trichoderma viride presented all enzymatic activities. Complex correlations and no-clear patterns were found between the airborne microorganisms and the environmental factors.

“…Another study has shown associations between hospital admissions for cardiovascular diseases and CODP attributed to an increase in the NO 2 From past to now, Ahvaz has been well-known due to industries as well as environmental pollution. In the last decade, an anthropogenic source of air pollution (dust storm) has joined to other environmental problems (29). Physical, chemical and biological characteristics of dust storm and also the identification of hazardous air pollutants, such as BTEX have been well-documented (29)(30)(31)(32).…”
