“…For 2007For , 2009 and 2011 important increases of this metal are registered especially in sections of Cisla River downstream of Baia Borşa City, which leads to the framing of water for Lăpuș, Cavnic and Săsar rivers.The presence of cadmium concentrations might be assigned to the wastewater discharge from the Ferneziu metallurgic plant (SC Romplumb SA) and upstream mining exploitations.…”

The paper highlights the current situation of the quality of surface water in the areas influenced by mining activities in the north-western part of Romania. In this respect a series of investigations have been conducted regarding the contamination with heavy metals of the water of the Someş and Tisa hydrographic Basins, which cover the northern part of Maramures County and the south-western area of Maramures County, respectively.The results of the comparative research refer to the period between 1999 and 2011 and reveal the specific heavy metal ions of mining activity: Fe, Mn, Zn, Cu, Pb Cd and Ni, as well as the water pH. The presented values as annual average values reveal an increase in several heavy metals after the closure of mines, which is due to the lack of effectiveness of the closure and of the conservation of the mine galleries, as well as of the impaired functioning of the mining wastewater treatment plants.

“…The risk associated with abandoned mines requires careful consideration because these dismissed mines can generate several forms of damage to the surrounding environment: collapse of large ar-eas, subsidence, pollution, etc. As reported by several authors [1][2][3][4][5], abandoned mines have serious implications for the land: a number of authors have studied the impact of mines on surface stability [6][7][8][9][10][11][12][13][14][15][16][17], while others have focused on pollution of the environment [18][19][20][21][22][23][24].…”

The risk of collapse in abandoned mine sites: the issue of data uncertainty

et al. 2016

Abstract:Ground collapses over abandoned underground mines constitute a new environmental risk in the world. The high risk associated with subsurface voids, together with lack of knowledge of the geometric and geomechanical features of mining areas, makes abandoned underground mines one of the current challenges for countries with a long mining history. In this study, a stability analysis of Montevecchia marl mine is performed in order to validate a general approach that takes into account the poor local information and the variability of the input data. The collapse risk was evaluated through a numerical approach that, starting with some simplifying assumptions, is able to provide an overview of the collapse probability. The nal results is an easy-accessible-transparent summary graph that shows the collapse probability. This approach may be useful for public administrators called upon to manage this environmental risk. The approach tries to simplify this complex problem in order to achieve a roughly risk assessment, but, since it relies on just a small amount of information, any nal user should be aware that a comprehensive and detailed risk scenario can be generated only through more exhaustive investigations.
