“…The data shown on the map is consistent with the results presented in the paper [54], in which passive biomonitoring with Pb-210 was used to assess the deposition of pollutants. The presented data demonstrate that allogenic Pb-210 may be used as a marker of environmental pollution and in places where its activity is increased one may expect pollutants associated, inter alia, with the local industry.…”

Radioactive isotopes, both natural and artificial, present in the environment, may be convenient indicators that can be used to study many physical and chemical processes as well as the transport of pollutants in the ecosystem. The studies have shown that in identification of particulate matter emission sources a radioactive lead isotope (Pb-210) can be used. The Pb-210 increased activity concentration in the top soil layers suggests its current atmospheric deposition. This conclusion is confirmed by the results of the Principal Components Analysis, conducted using the measured radionuclide content in 0-30 cm deep soil layer samples. Keywords: Pb-210, pollutant emission indicator IntroductionRadioactivity is not only a source of human exposure, but it also has many practical applications. Using the properties of radioactive isotopes, it is possible, for example, to generate electricity, test materials, diagnose and treat people. Radioisotopes are also used in environmental studies [1].Radioactive isotopes are used, inter alia, to study the mechanisms and dynamics of the processes in soil and plants , to determine the age of rocks, minerals, sediments and soil (eg C-14, U-238, U-235 and Th-232), to study the circulation of elements and their radioactive isotopes in the food chain and in the monitoring studies (natural isotopes, eg K-40, U-238, or artificial isotopes, [1].The examples of monitoring studies include the assessment of the activity of caesium isotopes in surface soil in spatial terms [2][3][4][5].Radioactive isotopes are also used in laboratory testing of processes under controlled conditions, which makes it possible to describe them and to assess the behavior in the environment. The use of these methods is presented, inter alia, in sample Australian studies 1 Independent Chair of Biotechnology and Molecular Biology, Opole University, ul. kard. B.

The use of Cs-134, Sr-85 and Zn-65 made it possible to determine the penetration of radioactive fallout into tropical soil. were used to identify the mechanism and dynamics of trace metal bonding in port sediments.Radioactive isotopes present in the environment, such as Th-234, Be-7, Pb-210, Cs-137, Si-32 and C-14, were used to study present-day sedimentation in seas and oceans. Th-234 and Be-7 isotopes are used, inter alia, in bioturbation and sedimentation studies in the high material supply conditions [7,8].Pb-210 isotope is most commonly used to determine the rate of marine [9] and lacustrine [10-14] sediment increase, but also to identify the rate of snow cover increase. The lead method was also used in Alpine glacier studies [15,16].Cs-137 is used, as a time marker, very often together with Pb-210, to determine the age of lacustrine sediments. The literature review shows that Cs-137 may be used to determine the rate of deposition of overbank [17,18], lacustrine and delta [19,...

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.
