Methodology of application of essential oils and their components to achieve fungistatic effect in depositories paper artifacts endangered by microbial attack due to high relative humidity
 Milichovský, M. ; Večeřa, Zbyněk ; Neuvirt, J.
Methodology concerns the protection of artifacts on paper using essential oils. It is the sum of knowledge, policies and procedures, as these substances or their analogs artificially prepared to use so as to avoid unnecessary mistakes to be protected negative impact on lignocellulosic materials.

Microbicidal properties and chemical composition of essential oils
 Křůmal, Kamil ; Večeřa, Zbyněk
The microbicidal properties of 6 essential oils (EOs; Lavandula angustifolia, Cymbopogon nardus, Citrus aurantifolia, Juniperus communis, Myrtus communis and Cinnamomum zeylanicum ) for 17 microorganisms were determined using the vapour-agar contact method. The most effective EO (i.e. Lavandula angustifolia ) whose volatile components provided the sufficient microbicidal properties was chosen for detailed study of chemical composition.

Determination of heavy metals in solid energetic waste
 Kořínková, Alena ; Doležalová Weissmannová, H.
Determination of heavy metals (Pb, Cu and Cd) in solid energetic waste (loge ash, ash, scoria) was performed according to Tessier. Extraction proceeded at temperatures of 25°C and 40°C and metals were determined using atomic absorption spectrometer (F AAS and ET AAS).

Comparison of concentrations of organic compounds in PM1 aerosol in Brno and Šlapanice
 Křůmal, Kamil ; Mikuška, Pavel ; Večeřa, Zbyněk
In this work the organic compounds and organic markers used for the identification of sources of aerosols were monitored. Monosaccharide anhydrides are emitted from biomass combustion, polyaromatic hydrocarbons from traffic and incomplete combustion, hopanes from traffic and coal combustion, steranes from traffic and fatty acids from cooking.
