Republicii 42, Cluj-Napoca, 400015 Abstract. A brief review of the Romanian lichenological studies is done; the main Romanian lichenologists and their research fields of interest are presented. The use of lichens as biomonitors is exemplified with a case study in the surroundings of Zlatna, a well known industrial centre in Transylvania (western part of Romania). The present paper synthesises the research work performed in the area in the last 20 years. The mineral processing plant and smelter of Zlatna town cause acid precipitation and heavy metal contamination due to gaseous emission (SO2, NOx) and fall-out of particles enriched in Pb, Zn, Cu, and Cd. The impact on the terrestrial environments consists in extremely high soil and vegetal lead level. The aim of this paper is to present the long term biomonitoring of different contaminant elements using passive and active monitoring methods based on the lichens in the studied area. In 1980, two corticolous lichen species, Parmelia conspersa and Lecanora subfusca, were transplanted into Zlatna area from an uncontaminated site. The results of short and long term exposure were compared, then the experiment was repeated after 5 years. In 1998, also the heavy metals content of samples of Cladonia fimbriata, tericolous native lichen located only outside the strongly polluted Zlatna town was investigated. The heavy metal content of the samples of Cladonia fimbriata was compared with that in soil samples collected from the same stationary. The results show that Zlatna region is excessively polluted, and can be included among the strongest polluted areas of the world. Key words: lichens, history, Romania, pollution, Zlatna, biomonitoring BRIEF SUMMARY OF ROMANIAN LICHENOLOGICAL STUDIES The debut of lichenology as an independent science in the field of botanical research was marked by the studies of Acharius (1803), who described the morphology of lichen thalli, showing that the soredia and apothecia play a reproductive role. Schwendener (1867-1869), by his theory on algal-fungi symbiosis underlined the complexity of lichens and thus lead to an increased scientific interest in this field. As in other European countries, before 1900 in Romania no paper exclusively dealing with the study of lichens was published. Lichens as components of the vegetal cover were only recorded besides mosses, pteridophytes and cormophytes. One can mention the studies of Heufler (1853), Schur (1859), Cserni (1877-1878), Simonkai (1893) and Barth (1877-1905) [4]. Between 1862 – 1878, Fuss [4] published a list of over 100 lichen species in the journal Verhandlungen und Mitteilungen des Siebenburgischen der Vereins für Naturwissenschaft, then additionally another 48 species in the in the Centuria issues I – XI. In his fundamental work Systematiche Aufzahlung der in Siebenburgen angegebonen Cryptogamen (1878), the third chapter contained exclusively data on lichens collected from Transylvania. The studies of Hazslinszky [4], concerning only cryptogams, were materialized as lichen research in the paper Magyar Birodalom zuzmóflórája (1884), the first book that contained all the current data on Transylvanian lichens for that period. Lojka (1873-1885) played an important role in the study of lichens in the same region, by describing numerous new species, in papers that are still considered as reference publications[4]. Before 1900, in the southern part of Romania (Vallachia), the activity of two botanists Kanitz (1879-1881) – who published about 22 lichen species collected from 1 Bucegi Mountains, Ceahlău Mountains and the peaks around Râmnicu-Vâlcea area, and Loitlesberger (1897) – who described two new species from Bucegi Mountains, are worth to mention [4]. Starting with the beginning of the XXth century, the number of papers on lichens increased considerably. In Moldavia,

    Scoping study: applicability of PIR systems to mine waters in Eastern and Southern Europe 151 27 SCOPING STUDY: APPLICABILITY OF PIR SYSTEMS TO MINE WATERS IN EASTERN AND SOUTHERN EUROPE 27.1 Project: PIRAMID C. Wolkersdorfer1, A. Hasche1, J. Tschapek1, M. Veselič2, M. Leblanc3 1University Freiberg, Germany 2Institute for Mining, Geotechnology and Environment, Slovenia 3Université Montpellier, France 27.2 Executive Summary Mining in Europe has great influence of the environment. A significant problem in many EU Member States and EU candidate countries is the long-term water pollution from abandoned mines and associated industrial sites. Sources of water pollution are e.g. pyrite oxidation, metal leaching by surface water or rain and leaching of residual process chemicals in the tailings. In order to reach today’s ecological standards polluted mine water needs to be treated in technical water treatment systems (conventional method). Water treatment will be necessary for a long time, consequently conventional methods will not be economically efficient. Key objectives of PIRAMID are to draw developments of passive, ecologically-friendly in-situ remedial methods for mining waters together and to support the development of new tech- niques and innovations in order to apply such technologies to a variety of of polluted mine waters. This report gives an overview of mine water problems in selected EU Member States and Accession States in Eastern and Southern Europe and assesses the potential applicability of passive treatment methods and where such methods are already applied. For most existing mining sites in the reviewed countries the applicability of passive treatment methods is possible. Furthermore, in France, Germany, Poland and the Czech Republic ex- periences with different passive treatment methods e.g.

  • Mtntng ACTTVTTIES Tn the APUSENT MOUNTATNS, ROMANTA
    Geosciences in the 27't century. ENVIRONMENTAL PROBLEMS ASSOCIATED WITH THE MtNtNG ACTTVTTIES tN THE APUSENT MOUNTATNS, ROMANTA Elena-Luisa IATAN lnstitute of Geodynamics ,,Sabba S. $tefdnescu" of Romanian Academy, D-21 Jeon-Louis Calderon St, o2oo32 Buchorest, e-mail: [email protected] Mining is one of the oldest industries, and abandoned mines with the potential to release harmful substances into soil, water and air are found throughout Romanian territory. Due to the mining activity of ore deposits for more than 2000 years, in Romania there are over 550 tailings dumps, covering an area of approximately 800 ha and storing over 200 million cubic meters of tailings and 54 tailings ponds, which covers an area of almost 1350 ha and stores over 350 million m3 of waste. Mining activities create a potential impact on the environment, both during exploitation and in the years after mine closure. Underground exploitation presents the risk of collapsing galleries and surface overflowing and involves the dislocation of a large amount of rocks. Quarrying is one of the most common forms of mineral extraction, being particularly harmful to the environment, as strategic minerals are often available in low concentrations, which increases the amount of ore extracted. Althou8h mininB activities are currently stopped in most areas, the potential risk of environmental contamination exists due to the huge quantities of tailings in the tailings ponds and the tailinBs dumps very close to the watercourses. These are permanent sources of pollution for surface and groundwater, soil and air in the area (Fig. 1). The oxidation of sulphide minerals led to the removal of soluble metal ions from the mineralization found in mining related wastes under the effect of water.

  • Hydrometeorological Risk Phenomena in the Alba Iulia – Turda Depression
    Hydrometeorological risk phenomena in the Alba iulia – Turda Depression. Romania CĂTĂLINA MĂRCULEŢ1, IOAN MĂRCULEŢ2, 1. Institute of Geography, Bucharest, Romania 2. "I.L. Caragiale" National College, Bucharest, Romania e-mail: [email protected] Abstract In order to assess the vulnerability of communities to extreme hydrometeorological phenomena, observations on their onset and development should aim at quantifying intensity and frequency, also establishing and foreseeing possible damage. The present study focuses on a few atmospheric phenomena registered in the Alba Iulia – Turda Depression over the 2002-2006 interval, given that the damage incurred involved aspects of risk. Hazardous atmospheric phenomena, heavy rainfall in the main, led to other natural risks affecting both the environment and the socio-economic activity. Apart from atmospheric causes, the risk for other natural events are related to local particularities, e.g. lithological structure (sandy-clay substrate), landform (slopes and highly fragmented relief) and soils (little forestland and grassland due to human pressure – dominantly arable land and numerous human settlements). Houses and annexes, as well as socio-economic constructions were damaged, lots of animals and poultry perished, national, county, communal and forester's roads, bridges and foot-bridges were washed away or disaffected, crops were flooded, trees were brought to the ground, electrical and telephone networks were destroyed. Heavily affected were the road infrastructure, the hydroelectrical constructions the socio- economic units, the electrical and telephone networks and agriculture generally. The number of catastrophic situations, unusually high in 2005, represented 44% of all the interventions made over the past ten years to limit and remove flood effects. Negative hydrometeorological phenomena were found to occur mainly in summer, especially in June and July when torrential rains and floods are common.

  • Considerations on the Acid Mine Drainage Discharges in Natural Receptors, from the Baia-Mare Former Mining Area
    STUDIA UBB AMBIENTUM, LIX, 1-2, 2014, pp. 87-95 (RECOMMENDED CITATION) CONSIDERATIONS ON THE ACID MINE DRAINAGE DISCHARGES IN NATURAL RECEPTORS, FROM THE BAIA-MARE FORMER MINING AREA Corina Ioana NEAMȚU1*, Elena Maria PICĂ1 1 Technical University of Cluj-Napoca, Faculty of Engineering Materials and Environment, 103-105 Muncii Boulevard, Cluj-Napoca, Romania * Corresponding author: [email protected] ABSTRACT. After more than a decade from the cessation of mining activity throughout Romania, acid mine drainage management has remained topical. The high content of heavy metals in mine water threatens the quality of surface water and groundwater, and thus the soil. Therefore, it is important to find suitable solutions to control the discharge of this water into the natural receptors, so that the environment is minimum damaged. This paper presents the situation of five mines in Baia-Mare area, Maramureș County (Câmpurele, Tyuzoșa, Ilba Handal – near Băița village, the gallery in the central area of Cavnic and Reiner gallery from the same town) as it is in 2013, both in terms of water treatment applied methods after the evacuation from the mine galleries, and the parameters values of water samples from these five mines. Key words: acid mine drainage, heavy metals, pollution, pH, electric conductivity INTRODUCTION The mining activities impact on the environment occurs in all phases of the production processes, beginning with the prospection of the ore deposit and intensifying with their exploitation phase (Fodor, 2006). Depending on the particularities of the area - the type of the ore deposit exploited, the topography, the soil type in the area, the area surface explored or the method of the ore extraction, the negative effects may occur over a long period of time, even after the stoppage of the mine work in the area.

Web: www.witpress.com Email [email protected] Paper from: Development and Application of Computer Techniques to Environmental Studies, CA Brebbia and P Zannetti (Editors). ISBN 1-85312-909-7 Characteristics of river flow in the Transylvanian Basin V. Sorocovschi & G. Pandi Department of Geography, Babes-Bolyai University, Romania Abstract One of the largest depression in the Romanian Carpathians, the Transylvanian Basin, occupies the central part of Romania, being a typical upland region. The river flow characteristics in the Transylvanian Basin have been pointed out as a result of data processing and interpretation activities carried out at 24 hydrometric stations. The humidity contrasts as a consequence of the territory exposure to the advection of oceanic air masses coming from the west are reflected by the distribution of the components of the hydrological balance, which has been presented in detail in the first section of the present paper. The second section focuses on the way in which the effects of the climatic demarcation influence the temporal distribution of the flow, the frequency flow rhythms, as well as on the territorial distribution of the types and subtypes of regime. 1 Introduction The Transylvanian Basin is the widest and the best individualized area with negative morphology in the Carpathian range, which covers 10.5’?/oof the Romanian territory (237,5000 km2). Because of its central position in the Carpathian-Danubian-Pontic area, the Transylvanian Basin is a place of convergence for several geographical elements, among which the rivers and the human potential are especially important.

Iorga, No.11-13, Alba, Romania bLocal Group of Action from Ampoi and Mureú Valleys, VinĠu de Jos, Alba, Romania cEconomic Studies Academy, Bucharest, Romania Abstract Rural areas have been modified during centuries of agriculture practice and, in the last decades, of other economic activities like mineral extractions and processing industry, including also touristic activity. A challenge for ensuring sustainable development in rural areas is to cover the development needs of the community. Tourism has been indicated as a good development strategy for Romanian rural areas. The article is presenting the advantages and limits in supporting touristic activity in the framework of Leader approach at the level of a Local Group of Action in Romania, Alba and Hunedoara Counties. Leader approach is offering limited support for rural area in order to encourage cultural activities, architecture rehabilitation, valorizing natural landscape and rural tourism. Through its direct and indirect impacts, tourism attracts significant foreign exchange, investment and know-how and stimulates the local economy, with a significant multiplier effect on many other areas of the economy. In the same time, it has to be paid a great attention to the effects generated upon the rural communities by the tourists’ activities.
