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

Table 1

Microbial air concentration obtained at Argentinean archives.

Archives	CFU · m^−3
	Fungi	Bacteria	Total microorganisms*	𝑇 (°C)	RH (%)
HAMLP	120^a	100^d	220	19.7 ± 1.4	50.6 ± 5.1
AHCRD	1271^b	1422^e	2693	18.7 ± 1.6	50.1 ± 5.2

^a,b,c,d,e,fIndicates significant differences according to the Duncan test (P ≤ 0.05) on comparing the environmental concentration of fungi and bacteria among different Argentinean archives. The microbial determination was made in 5 points by triplicate and the data averaged (𝑛=45). *Indicates the sum of the median concentration of fungi and bacteria.
