Innovation in Study of Physical and Technical Measurements. Czech-Polish Cooperation of Universities / Innowacje Studiów Fizyczne I Techniczne Metody Pomiarowe. Czesko-Polska Współpraca Uniwersytetów

Abstract

In the Faculty of Science (University of Hradec Králové) the innovative program in chemistry for the study specialization Physico-technical Measurements and Computer Technology was developed. The innovation of chemistry filed study has been focused especially on increase in competitiveness and in graduates employment. Design of innovation enables graduates applying for the position of experts in physical measurements and informatics and at the same time they expand their competence in the service of the physico-chemical instrumentation in industrial ecology. Because Faculty of Science is not equipped yet in expensive instrumentation for nuclear spectrometry, cross-border cooperation with the Faculty of Natural and Technical Sciences (University of Opole) has been started. In the area of teaching about non-traditional energy sources the cross-border cooperation with the Department of Automation and Renewable Energy Sources, Faculty of Electrical Engineering (Czestochowa University of Technology) has been initiated. Well-developed system of cooperation with companies, which are equipped with the latest technology of environmental protection, was created. In the exchange system Polish students attended for practicing in these companies. The aim of the contribution is to describe one of the means of innovation of chemistry field study in the frame of bachelor study specialization oriented in physics and computer technology. We believe that the new approach will lead to increase in graduate competitiveness as well as to development of their motivation to study and better understanding of regulation principles of chemical processes and patterns.

Modelling of Mercury Emissions from Large Solid Fuel Combustion and Biomonitoring in CZ-PL Border Region

Abstract

Tightening of norms for air protection leads to a development of new and significantly more effective techniques for removing particulate matter, SOx and NOx from flue gas which originates from large solid fuel combustion. Recently, it has been found that combinations of these environmental technologies can also lead to the reduction of mercury emissions from coal power plants. Now the greatest attention is paid especially to the coal power plant in Opatovice nad Labem, close to Hradec Kralove. Its system for flue gas dedusting was replaced by a modern type of cloth fabric filter with the highest particle separation efficiency which belongs to the category of BAT. Using this technology, together with modernization of the desulphurisation device and increasing of nitrogen oxides removal efficiency, leads also to a reduction of mercury emissions from this power plant. The University of Hradec Kralove, the Opole University and EMPLA Hradec Kralove successfully cooperate in the field of toxic metals biomonitoring almost 20 years. In the Czech-Polish border region, comprehensive biomonitoring of mercury in bioindicators Xerocomus badius in 9 long-term monitored reference points is done. The values of mercury concentration measured in 2012 and 2016 were compared with values computed by a dispersion model SYMOS′97 (updated 2014). Thanks to modern methods of dedusting and desulphurisation, emissions of mercury from this large coal power plant are now smaller than before and that the downward trends continues. The results indicate that Xerocomus badius is a suitable bioindicator for a long-term monitoring of changes in mercury imissions in this forested border region. This finding is significant because it shows that this region is suitable for leisure, recreation, and rehabilitation.
