The
highest growth of fungal contamination during afternoons
was observed in the chemical laboratory (in 2003 – 5.8
times higher in afternoons than in mornings) and in the library
reading room (in 2002 – 8.5 and in 2003 – 7.3 times
higher in afternoons than in mornings). In the remaining
air samples the level of fungal growth was lower, i.e. up
to 3 times higher than in mornings.
