Table 1 Qualitative and quantitative analysis of chromatograms acquired for MVOCs emitted by selected species of moulds growing on the model material samples and the historic sample

Species/samples/medium	Oct-1-en-3-ol, Octan-3-ol, Oct-1-en-3-one, Octan-3-one, Octan-2-one (t_R 18.50–21.00)^a	Hexan-2-one (t_R 4.50–5.50)^a Heptan-2-one (t_R 16.00–16.20)^a	Terpenes sesqui-terpenes (t_R 30.00–35.00)^a	Compounds with sulfur (t_R 40.00–45.00)^a	Total concentration of the indicatory volatiles [µg m⁻³]^b
A. niger IHEM:2312/silk/W&C	++++	++	+++++++++	++++	62.0 ± 3.5
A. fumigatus IHEM:1363/parchment/Cz&D	++	++	+++++	+	24.0 ± 2
C. herbarum IHEM:5294/NOVO test paper/Cz&D	++	+	+++++	–	34 ± 1
T. viride IHEM:3170/Whatman paper/Cz&D	++	+	++++++++	–	21 ± 1
C. globosum IHEM:6552/wool/W&C	++	++	++++	++++++	58 ± 23
T. viride IHEM:3170 on historical sample of wool	+++	+	+++	++++	19 ± 5

The number of “+” indicates that the how many of the volatiles which are defined in the head-row of the table was were identified in chromatogram
^a Retention time in chromatograms [min]
^b This is the sum of mean concentrations determined for each compound listed in the head-row of the second, third and fourth column; the standard deviation was calculated for each sum based on the variances
