Abstract A biomonitoring technique never before used in the Czech Republic was used to test its validity and applicability in the region of Ostrava that is eminently affected by industry. Transplants of two moss species Hylocomium splendens and Pleurozium schreberi were exposed to atmospheric pollution using the technique of an “irrigated moss bag” placed at a height of both 1 m and 2 m above ground. The samples were then analysed for concentration levels of trace elements Al, As, Cd, Cr, Cu, Fe, Hg, Pb, V and Zn. The patterns of bioaccumulation in general show that Hylocomium splendens is more suitable for monitoring purposes and that 2 m height above ground of transplants should be preferred.

Deposits of coal combustion wastes, especially fly ash, are sources of environmental and health risks in industrial regions. Recently, fly ash deposits have been reported as habitat surrogates for some threatened arthropods in Central Europe. However, the potential environmental risks of fly ash have not yet been assessed in the region. We analysed concentrations of 19 minor and trace elements in 19 lignite combustion waste deposits in the Czech Republic. We assessed their environmental risks by comparison with the national and EU legislation limits, and with several commonly used indices. Over 50% of the samples exceeded the Czech national limits for As, Cu, V, or Zn, whilst only V exceeded the EU limits. For some studied elements, the high-risk indices were detected in several localities. Nevertheless, the measured water characteristics, the long-term presence of fly ash, previous leaching by acid rains, and the low amount of organic matter altogether can infer low biological availability of these elements. We presume the revealed high concentrations of some heavy metals at some studied sites can be harmful for some colonising species. Nevertheless, more ecotoxicological research on particular species is needed for final decision on their conservation potential for terrestrial and freshwater biota.

Photosynthesis And Respiration

Fumigation with SO2 of the three feather mosses Pleurozium schreberi, Hylocomium splendens, and Ptilium crista-castrensis results in an immediate decline in their rate of photosynthesis but has no effect upon respiration. Pleurozium schreberi is the most sensitive of the three species, even though they all take up the same amount of SO2. Thus, the feather moss species appear to have similar degrees of SO2 avoidance (uptake) but dissimilar degrees of SO2 tolerance. With increasing desiccation, respiration declines equally in all three species, but photosynthesis declines most rapidly for P. schreberi. The immediate effects of SO2 upon photosynthesis of water-limited and of fully hydrated feather mosses are similar, but after a 24-h recovery period in an SO2-free environment photosynthesis remains impaired only in those mosses fumigated in the fully hydrated state. This probably is related to the larger amounts of SO2 absorbed by hydrated mosses.

Abstract For the third time since 2005 atmospheric deposition of trace elements in Belarus was monitored by the moss technique widely used in Europe for air pollution studies. Samples of moss species of Hylocomium splendens and Pleurozium schreberi were collected at 86 sites over the Gomel, Vitebsk and Minsk Regions in the summer of 2015. A total of 30 elements were determined by epithermal neutron activation analysis. Studying of the temporal trends in Belarus was undertaken with the results obtained in previous moss surveys in 2005/2006 and 2010/2011. Comparison with the analogous data from the neighbouring countries showed relatively low contamination levels in Belarus for the most heavy and toxic elements. The results of survey 2010/2011 showed that, except Cr, other element concentrations reduce or are at the same levels.

The review presents the analysis of publications dedicated to problems of using of Bryobionta representatives for bryogeochemical indication and biomonitoring of heavy metals and radionuclides in the environment. Taxonomic structure of Bryobionta is briefly observed, three divisions of Bryobionta are elucidated – Anthocerotophyta, Marchantiophyta and Bryophyta. It is concluded that the most suitable moss species for biomonitoring of heavy metals and radionuclides are representatives from division Bryophyta, such as Hylocomium splendens, Pleurozium schreberi, Hypnum cupressiforme, Scleropodium purum. The mosses have been successfully used in biomonitoring of atmospheric fallout of heavy metals in the environment in Europe for 25 years. A special system of monitoring on their basis is applied in 28 countries of the continent. For the most important moss species used as test-objects of biomonitoring, significant width of their geographic distribution is shown as well as distribution on different substrates of growth (epigeious, epiphytic, epilytic). The main biological peculiarities of mosses which allow to use them for purposes of biomonitoring of heavy metals and radionuclides have been analyzed, i.e. absence of roots, that permits them to derive the main part of nutrients (and pollutants) directly from aerial fallouts – dry (dust) and wet (rain, snow), and high cation exchange capacity of their cell membranes. The most important anatomical and morphological features of three moss groups (endohydritic, ectohydritic, mixohydritic) are briefly reported, and a conclusion about the best suitability of ectohydritic moss species for bryogeochemical indication and biomonitoring of pollutants is made. Results of numerous biomonitoring studies conducted with using of widely distributed moss species in Europe in nature and anthropogenic biogeocenoses are demonstrated. Criteria to mosses as test-objects of bryogeochemical indication and biomonitoring are briefly reported. Physiological adaptations of mosses to stress emerging due to intake of significant concentrations of heavy metals to their phytomass are generalized. Requirements to sampling of moss cover for purposes of bryogeochemical indication and biomonitoring of pollutants are reported. Perspective moss species as test-objects of environmental pollution by heavy metals and radionuclides are proposed for different natural zones of Ukraine: for Polissya zone – Hylocomium splendens and Pleurozium schreberi, for Forest-Steppe zone – Hypnum cupressiforme, for Steppe zone – Tortula muralis and Bryum argenteum.
