Characterization of Metals in Atmospheric Aerosol
Cigánková, Hana ; Ličbinský, Roman (referee) ; Vojtíšek,, Michal (referee) ; Krajčovič, Jozef (advisor)
The presented doctoral thesis deals with the characterization of elements in two size fractions of urban aerosol, which was sampled in all seasons on the terrace of the Institute of Analytical Chemistry of the CAS in Brno in 2018. The theoretical part of the thesis summarizes the basic information about the analysis and health risks of atmospheric aerosol and metals bound to aerosol. Furthermore, the work describes methods for determining the inhalation bioaccessibility of aerosol particles and methods used for the determination of oxidative potential. The first part of the thesis describes in detail the sampling and analysis of urban aerosol particles. The mass concentration of both aerosol size fractions and the total concentration of 21 elements were determined. The probable sources of the analysed elements were calculated using the enrichment factor and positive matrix factorization. The second part of the thesis deals with the determination of the oxidative potential of the aerosol and bioaccessible concentration of the analysed elements in three simulated lung fluids (deionized water, simulated alveoli fluid, Gamble solution). In addition to determining the oxidative potential of real samples, the oxidative potential of individual elements was also analysed. From the obtained results was calculated the probable contribution of the elements to the measured oxidative potential.
Air quality monitoring in areas with high traffic load
Ličbinský, Roman ; Huzlík, Jiří ; Hegrová, Jitka
Emissions of pollutants are one of the most serious problems of transportation, particularly as a result of a significant risk to human health. The causes of emissions of pollutants to ambient air are the exhaust gases generated by the combustion of fuel in motor vehicles. They are complex mixtures containing hundreds of chemical substances at different concentrations contributing to long-term warming of the atmosphere, the so-called "greenhouse effect" or often with toxic, mutagenic and carcinogenic properties for humans. The presented methodology was developed within project TE01020168 - Center for effective and sustainable transport infrastructure (CESTI) with the financial support of the Technological Agency of the Czech Republic within the Competence Centres Programme. Its aim is to unify the procedures for the implementation and evaluation of air quality monitoring in order to provide objective information on the actual status and development of air quality in areas with intensive transport. It summarizes the legislatively defined requirements for air quality monitoring and at the same time defines the pollutants whose very important source is transport and which should be monitored when assessing the impact of transport on air quality: nitrogen dioxide, (nano)particles, benzene, or platinum group elements and benzo[a]pyrene. The methodology can be used by the Ministry of Transport, road owners or their managers (ŘSD, regions and municipalities) as an effective tool for controlling both long-term monitoring and indicative measurements of air quality in the vicinity of roadways. At the same time, it will find application to metering processors and organizations providing their own air quality measurement to provide a standardized procedure to ensure a precise air quality assessment based on real data. The methodology will also help to deepen the knowledge of the staff of all the mentioned institutions and provide a standardized procedure for which, for example, contracting authorities may refer to public procurement.

Toxicity Assessment of Firewaters
Rybková, Tereza ; Ličbinský, Roman (referee) ; Adamec, Vladimír (advisor)
The issue of toxic extinguishing water is currently getting more to the fore. When a fire arises a wide range of hazardous substances that may negatively affect the quality of some components of the environment. A significant problem can be then extinguishing water runoff into sewers or some components of the environment. The objective is to assess the ecotoxicological properties of extinguishing water, determine the toxicity of the extinguishing water by experiments and thus contribute to the deepening of knowledge in so very few solved problems.
Morfologie‚ chemická a toxikologická charakteristika pouličního prachu a suspendovaných prachových částic‚ včetně určení zdrojů původu
Centrum dopravního výzkumu, v.v.i., Brno ; Del favero, David ; Dočekal, Bohumil ; Večeřa, Zbyněk ; Mikuška, Pavel ; Ličbinský, Roman ; Huzlík, Jiří ; Adamec, Vladimír
Cílem řešení projektu je prohloubení znalostí a získání nových poznatků o chování, složení, morfologii a zdrojích pouličního prachu, a tím i suspendovaných pevných částic na lokalitách zatížených mobilními zdroji znečištění. Hodnocení vlivu látek vyskytujících se v ovzduší na sledovaných lokalitách (Brno - Kotlářská, Ostrava - Bartovice) jak z pohledu životního prostředí (toxikologické testy), tak zdraví člověka (odhad zdravotních rizik shodně označují ve sledovaných faktorech za více zatíženou lokalitu Brno Bartovice, i když druhou lokalitu nelze označit za vyhovující. Odhad celkového individuálního karcinogenního rizika je vyšší než uznávaná zdravotně bezpečná hodnota na všech sledovaných lokalitách.

Environmental and economical evaluation of clean vehicles promotion: Final report
Špička, Libor ; Dostál, Ivo ; Dufek, Jiří ; Jedlička, Jiří ; Ličbinský, Roman
This project was focused on environmental and economic assessment of tools for indirect promoting of clean vehicles. During the solution was proposed a set of possible support tools. The locality for application of tools was identified on the basis of air quality analysis. For the chosen city was created and calibrated the traffic model which was extended by two scenarios. These scenarios include a set of proposed tools for promoting of clean vehicles. The chosen scenarios were assessed environmentally and compared with the basic present state. On the basis of the environmental assessment was prepared the dispersion studies which were used as a basis for the assessment of impacts on human health. Other outputs of environmental assessment were used for the economic evaluation of proposed tools for promoting of clean vehicles.
