“…Indoor particle concentration was modeled for different size intervals using equation (4). Since, the air exchange rate of the library was estimated by CO 2 measurements, the only requirements in equation (4) is to find the appropriate values for deposition rate k and penetration efficiency P using the continuous outdoor particle concentration.…”

“…Numerous studies have already focused on indoor air characterization of libraries and museums with regard to chemical pollutants, indoors sources, chemical reactions and environmental factors [4,[6][7][8][18][19][20][21][22][23]2,24]. Moreover, the characteristics of indoor PM in museums were also studied with regard to the outdoor environment [7,9,25,26].…”

As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. A dynamic mass balance model was introduced taking account particle penetration from outdoors and indoor losses (deposition, ventilation). The model was used to determine deposition rate k and penetration efficiency P in 13 discrete size intervals. Model performance was evaluated using the coefficient of determination (R 2 ) by selecting different pairs of k and P. No unique solution found, thus, averaged values of k and P from the best correlated pairs were used to estimate infiltration factor. Good agreement between infiltration factor and I/O ratio confirmed that modeled k and P were well-estimated. The deposition rate was found to depend strongly on particle size with higher rates for ultrafine and coarse particles. Penetration efficiency, on the other hand, was not clearly related with particle size. The infiltration factor varied substantially with particle size with less effective removal for accumulation fraction (0.1-0.7 µm). Higher infiltration factor for ultrafine particles, compared to coarse particles, indicates that enrichment of the library at this size is caused by penetration from outdoors. On the other hand, human presence during visiting hours found to contribute significantly to coarse particles by increasing the indoor number concentration by a factor of 3, 3.2 and 2 during spring, summer and winter respectively.

“…SO 2 , NO x , and O 3 are known to be the main externally generated pollutants causing heritage material degradation (Camuffo et al, 2001;Camuffo et al, 1999). With the decline of concentrations of traffic-generated pollutants as a result of strict environmental regulations in the last decade, in heritage institutions the focus is slowly shifting towards indoor-generated pollutants, particularly organic acids (Ryhl-Svendsen and Glastrup, 2002;Schieweck et al, 2005).…”

Volatile aldehydes are produced during degradation of paper-based materials. This may result in their accumulation in archival and library repositories. However, no systematic study has been performed so far. In the frame of this study, passive sampling was carried out at ten locations in four libraries and archives. Despite the very variable sampling locations, no major differences were found, although air-filtered repositories were found to have lower concentrations while a non-ventilated newspaper repository exhibited the highest concentrations of volatile aldehydes (formaldehyde, acetaldehyde, furfural and hexanal). Five employees in one institution were also provided with personal passive samplers to investigate employees' exposure to volatile aldehydes. All values were lower than the presently valid exposure limits.The concentration of volatile aldehydes, acetic acid, and volatile organic compounds (VOCs) in general was also compared with that of outdoor-generated pollutants. It was evident that inside the repository and particularly inside archival boxes, the concentration of VOCs and acetic acid was much higher than the concentration of outdoor-generated pollutants, which are otherwise more routinely studied in connection with heritage materials. This indicates that further work on the pro-degradative effect of VOCs on heritage materials is necessary and that monitoring of VOCs in heritage institutions should become more widespread.

Ar.thro.bac'ter. Gr. n. arthron a joint; N.L. masc. n. bacter a rod; N.L. masc. n. Arthrobacter a jointed rod.The majority of species exhibit a marked rodcoccus growth cycle when grown in complex media; stationary-phase cultures (generally after 2-7 d) are composed entirely or largely of coccoid cells that are 0.6-1.0 μm in diameter; some species are showing only spherical cells throughout the growth cycle. Fatty acids are predominantly iso-and anteiso-branched with C 15:0 anteiso, C 15:0 iso, C 17:0 anteiso, and C 16:0 iso predominating. Few species exhibit significant amounts of C 16:0 . Quinone system is composed of completely unsaturated or mono-saturated menaquinones with chain lengths of eight to ten isoprenoic units. The cell-wall peptidoglycan contains the diagnostic diamino acid lysine with several variations in the interpeptide bridge conforming to peptidoglycan type A3α or A4α.DNA G + C content (mol %): 55-72.

(2000) even detected Arthrobacter strains in terrestrial subsurface sediments at depths between 170 and 220 m.In the previous edition of Bergey's Manual of Systematic Bacteriology, Keddie et al. (1986) subdivided the genus Arthrobacter into two groups, the Arthrobacter globiformis/Arthrobacter citreus group and the Arthrobacter nicotianae group. Common characteristics of the Arthrobacter globiformis/Arthrobacter citreus group were the presence of the menaquinone MK-9(H 2 ) system and peptidoglycan type A3α, with the characteristic diamino acid L-lysine and an interpeptide chain consisting of monocarboxylic L-amino acids, glycine, or both (Schleifer and Kandler, 1972 Figure 1); Arthrobacter picolinophilus [according to Koch et al. (1995) Chun et al. (2001), this species is a later heterotypic synonym of Pseudomonas putida]. Other species showing meso-or LL-diaminopimelic acid as the characteristic diamino acid in the peptidoglycan were listed in two addenda: Arthrobacter ................................................................................................................................................................................................. Based on the amino acid composition of the peptidoglycan interpeptide chain, another grouping of Arthrobacter species was proposed by Komagata and Suzuki (1987) which dissected Arthrobacter species into seven groups designated Komagata/Suzuki groups I-VII (Table 1).At present, the genus Arthrobacter consists of 64 recognized species. Based upon the EzTaxon server (Chun et al., 2007), with the exception of Arthrobacter viscosus, these Arthrobacter species share 16S rRNA gene sequence similarities of 94.4-99.3% with the type strain of the genus, Arthrobacter globiformis. Several species of related genera such as Acaricomes, Brachybacteriu...
