Types and Quantities of Airborne Fungi in Loei Rajabhat University Library

Abstract

This study aimed to evaluate types and quantities of airborne fungi in Loei
Rajabhat University Library. The sample were collected from 3 floors composed of 344
plates (1st floor 15 sites 120 plates, 2nd floor 15 points 120 plates and 3rd floor 13 points
104 plates). All plates were collected by using single stage viable Andersen Impactor (N6).
The investigation was performed in 4 months (November 2012 – February 2013).
The results showed 4 airborne fungi composed of Aspergillus spp., Penicillium spp.,
Fusarium spp. and Curvularia spp. were found and the quantities were 1.712±1.918 cfu/m3,
Penicillium spp. 1.154±0.683 cfu/m3, Fusarium spp. 0.030±0.055 cfu/m3 and Curvularia spp.
0.015±0.042 cfu/m3, respectively. The airborne fungi airborne average of 3 floors was
2.912±2.698 cfu/m3. (5.242±4.852 cfu/m3, 2.277±2.088 cfu/m3 and 1.212±1.153 cfu/m3,
respectively) (standard fungi indoor air <50 cfu/m3, WHO ). The average indoor air temperature
and humidity were 28.31±1.02๐C and 64.63±7.72% and the average temperature and
humidity of outdoor air were 28.81±1.03๐C and 62.43±7.43%.
This study is useful for planning of cleaning schedule and ventilation system
management, including the air condition filters cleaning that can be reduced dust and
airborne fungi which contaminated in the library air.
