Abstract
According to the distribution of mold in students dormitories at Thaksin University,Phatthalung campus.
The aims of this study were to enumerate and identify mold in some rooms of these dormitories, however,
the relative humidity (RH) and temperature (RT) of the rooms were measured as well. The results showed that RH
and RT were between 66 – 88 % and 27.0 – 32.0 C., respectively. By using 2 methods of collecting mold
samples from 60 rooms including air settling method and cotton swab technique, the results were shown that there
were varieties of mold growing in all rooms at closets , tables, beds, ceilings and doors. The enumeration of mold
were 2.6×102 – 3.0 ×103 CFU/D and < 10 - < 1.3×106CFU/100cm2,respectively. One hundred and fifty - three
isolates were also collected and identified by using of culture and microscopic characteristics of mold, the results
showed that all isolates were able to be identified as Alternaria spp., Aspergillus spp.,Curvularia spp., Fusarium
spp., Geotrichum spp., Penicillium spp., and Rhizopus spp. 24, 38, 16, 20, 8, 34 and 13 isolates,respectively. The
results showed that the health of occupants might be harmful if prolonged exposure to mold. The symptoms of
disease by mold are eye irritation, nasal stuffiness,wheezing, ringworm, allergies, asthma, respiratory disease, Hay
fever and etc. Moreover mold can cause food spoilage and damage appliances. The methods of eliminating mold
are removing and killing them by applying bleach solution as well as reducing the moisture content in the air and
repaint the furniture with microban paint.
