Assessment of exceedance of critical levels for ozone in Slovak forest ecosystems
2002
Pavlendova, H. | Mindas, J. (Forest Research Institute, Zvolen (Slovak Republic))
For assessment of ozone risks to forests we used ozone thresholds and air quality guidelines set by several international organizations for protection of vegetation. We also used spatial modelling for estimation of basic ozone characteristics. Calculations of models were performed in the environment of the programme Idrisi 32. The spatial coverage of ozone monitoring network in the Slovak Republic has insufficient density. Ozone data come from two sources; SHMI/EMEP database of ozone concentrations from 4 monitoring stations and ozone database of FRI from 3 monitoring stations

Soil microorganisms are important for plant growth and beneficial for the nutrition and the development of a variety of soil animals. Together with soil invertebrates they also improve nutrients availability in soils. Although not frequent in Europe , magnesite emissions can affect the nutritional status of the vegetation and the survival of soil microorganisms as well as other biota locally, and thus may be crucially responsible for the quality of the entire biotic system. The observed gradients of soil microbial characteristics reflect the physico-chemical properties of soils around the magnesite plant and may be used to predict transitory changes during amelioration

2002
Pavlenda, P. (Forest Research Institute, Zvolen (Slovak Republic))
Forest soil condition in Slovakia harmonised with the programme ICP Forests has been monitored since 1988. There are presented some results of the first complete survey for 111 observation plots and three sampling depths (overlaying humus layer, 0-10 cm and 10-20 cm layer of mineral soil). Geological and geochemical diversity has resulted in rather differentiated forest soil condition and soil properties in Slovakia. That has strong effect on sensitivity to soil acidification as well as it brings other risks of air pollution impact

The terrestrial moss Hypnum cupressiforme was collected in the surroundings of oil plant Slovnaft (Slovakia) and oil industry in Ploiesti (Romania) to monitor heavy metal atmospheric deposition. A comparative evaluation of heavy metal atmospheric deposition recorded at the two locations versus a background area in Europe as Norway is presented. The highest concentrations were observed for V, Cr, Fe, Co, Ni and As at Ploiesti and for V, Cr, Fe, Co, and Ag at Slovnaft. This moss is very useful as biomonitoring organism to indicate and characterize deposition of atmospheric pollutants nearby oil plants

2002
Mankovska, B. (Forest Research Institute, Zvolen (Slovak Republic)) | Florek, M.: Frontasyeva, M. V. | Ermakova, E. V. | Oprea, K. | Pavlov, S. S.
The mosses Pleurozium schreberi, Hylocomium splendes and Dicranum scoparium were used as biomonitors to study the atmospheric deposition of heavy metals on the territory of Slovakia. The samples of mosses were collected on 86 permanent plots. Comparison with limit values from Norway shows strong pollution of the examined areas of Slovakia with many different heavy metals. The maximum level of pollution by heavy metals was observed in the region Gemer-Spis. The most important feature of sampling is that it correlates with the European Moss-Survey-2000 and the results obtained will be incorporated in the Atlas of Heavy Metal Atmospheric Deposition in Europe

2002
Mankovska, B. (Forest Research Institute, Zvolen (Slovak Republic))
Presented paper based on long-term and systematic research of the negative effect of pollutants and of the content of the elements in particular parts of forest environment (the years 1965/2002) proves of the importance, need and justificatin of the research on given subject. Knowing the elemental composition of pollutants as to its quality and quantity is basic precondition with diagnosing the effect of polluted air on forest environment. For the needs of practice three main pollution deposition types (acid, alkaline and ammonia) and 8 subtypes were established. They represent changes of forest ecosystems caused by different substances from pollutants
