Determination of Indoor Air Quality in Archives and Biodeterioration of the Documentary Heritage

Table 2

Microbial air concentration obtained at the repositories of the National Archive of the Republic of Cuba (NARC).

Repositories	CFU · m^−3
	Fungi	Bacteria	Total microorganisms*	𝑇 (°C)	RH (%)
Map library (ML)	60^a	502^c	562	24.0 ± 0.1	52 ± 1.0
Photo library (PL)	261^b	1149^d	1410	28.0 ± 0.5	65 ± 1.0

^a,b,c,dIndicates significant differences according to the Student’s test (𝑃 ≤ 0.05) on comparing the fungi and bacteria concentration between the repositories of NARC. The microbial determination was made in 5 and 2 points by triplicate, respectively and the data averaged (𝑛=21). *Indicates the sum of the median concentration of fungi and bacteria.
