Dust in Libraries
Mašková, Ludmila ; Smolík, Jiří
Indoor air pollution in libraries and archives can be harmful for materials stored there. Adverse effects of most of gaseous pollutants are well described, but less is known about dust. Dust particles cover a wide range of sizes and have a variable composition. These characteristics determine their transport to the surfaces and also possible harmful effects. Dust particles not only cause soiling, but coarse particles can damage surfaces by abrasion. Fine particles of acidic or alkaline character may penetrate into the books where they may cause chemical degradation or moistening due to their hygroscopicity. Dust particles in the indoor environment of libraries and archives are studied in a project which aim is a development of evaluation methods for indoor air quality, targeted at reduction of damages on archival collections caused by adverse effects of environment.

Basamatikum - Combined Wide Size Range Aerosol Spectromeeter
Ondráček, Jakub ; Mašková, Ludmila ; Smolík, Jiří
Combined wide size range aerosol spectrometer Basamatikum allows to measure particle number size distribution in a range between 20 nm – 20 μm. The instrument separates the measured aerosol particles into 58 size bins. The instrument can automatically switch the scanning between two sampling points (e.g. indoors and outdoors). It consists basically from two aerosol spectrometers (UFPM and APS), electrically actuated ball valve, sampling tubing with isokinetic subsampling to both of the two spectrometers and two sampling lines. The overall control, data logging and saving to file, the switching between sampling lines and the user interface is provided by the means of the LACP-made (Laboratory of Aerosol Chemistry and Physics) software in LabVIEW programming environment.

Air Quality in Different Types of Archives
Mašková, Ludmila ; Smolík, Jiří ; Ondráček, Jakub
Particulate matter (PM) and gaseous pollutants in libraries and archives can be harmful for materials stored there. The study includes indoor/outdoor monitoring of air quality in 4 archives, which representing different outdoor environments: Zlatá Koruna (rural), Třeboň (small city), Teplice (industrial area), and Prague (large city with traffic). The aim of this study is to investigate concentrations and sources of airborne PM and gaseous pollutants in the indoor environment of the archives, and to establish the relationship between the indoor and outdoor environment. The results indicated outdoor air as the most probable source of particles in the indoor environment of naturally ventilated archives at Zlatá Koruna, Třeboň and Teplice. The concentrations in the indoor environment in Prague are relatively constant and low, because the archive is equipped with a sophisticated filtration systém.

Air Quality in Different Types of Archives
Mašková, Ludmila ; Smolík, Jiří
The study includes indoor/outdoor monitoring of the air quality in four archives in the Czech Republic, which representing different outdoor environments: Zlatá Koruna (rural), Třeboň (small city with seasonal tourism), Teplice (industrial area), and Prague (large city with traffic). The aim of this study is to investigate concentrations and sources of airborne PM and gaseous pollutants in the indoor environment of the archives, and to establish the relationship between the indoor and outdoor environment. In 2012 the measurements were performed at Třeboň and Zlatá Koruna during 4 intensive campaigns in different seasons of the year.

Aerosol Particles in the Indoor Environment of the Týn Church in Prague
Mašková, Ludmila ; Smolík, Jiří
Particulate matter inside cultural heritage buildings possesses different degrees of risk to materials. Particles not only cause soiling but are abrasive, provide sites for surface reactions and have a potential to damage artifacts due to their hygroscopic nature (Hachtfield, 2005, Nazaroff et al., 1990). The aim of this study was to investigate concentrations and sources of airborne PM in the indoor environment of the Týn Cathedral in Prague.

Air Quality in the Indoor Environment of Libraries and Archives
Mašková, Ludmila ; Smolík, Jiří
The aim of this study is to investigate concentrations and sources of airborne PM and gaseous pollutants in the indoor environment of the archives, and to establish the relationship between the indoor and outdoor environment. In 2012 the measurements take place at Zlatá Koruna and Třeboň and in 2013 at Osek and Prague. The results indicated outdoor air as the most probable source of particles in the indoor environment of archives at Zlatá Koruna and Třeboň. The penetration of particles at Třeboň was higher than at Zlatá Koruna. These results were confirmed by measurements of ventilation rate, which was at Třeboň almost ten times higher than at Zlatá Koruna.
