This paper is focused on the microclimatic research in several buildings and ro
oms
used for sport at the University.
The attention is paid mainly to the problems of dimensions of
space, capacity and activity of sportsmen, and influence of space ventilation. The air samples for
microbiological analyses were taken by the microbial air
sampler Merck Mas
-
100 Eco and
cultivated by potato
-
dextrose agar and nutrient agar.
Captured microorganisms, are expressed as
colony forming units per
m
3
(CFU
m
-
3
).
Measurement results showed that bacteria average
quantity was statistically significantly less
without students
(562
CFU
m
-
3
) than
with students
(1,024
CFU
m
-
3
).
The students inside the rooms increased the bacteria concentration.
From this
point of view th
e ventilation is not adequate for the removal of bacteria from ventilated spaces.
From the results we can conclude that the great importance on the air quality in terms of a specific
bacteria concentration has the specific volume of the room per one athlet
e. The worst situation is
in rooms with the smallest volume, which has the largest biological load of the space.
The lowest
quantity of bacteria was in the swimming pool all year round (152 to 300
CFU
m
-
3
). The opposite
situation was in average quantity of
filamentous fungi, which was
with students and ventilation
(57
CFU
m
-
3
) and
without students but without ventilation
(109
CFU
m
-
3
).
The pollution of air
by fungi
was higher without ventilation.
