From contaminated mining areas, contaminants can migrate to different components of the environment, being favored by physicochemical transfer mechanisms such as their transfer into water. The dispersion of metallic contaminants from closed mining sites in surface waters is favored by the topography, climate and lithology of the area. In the Brad mining area, activity has ceased for about 15 years. Properly unnamed tailings and coastal galleries are a diffuse source of surface water pollution. The paper aims to as...

Land contamination generated by non-metallic mining activities through inappropriate handling and storage of industrial wastes and mine waters that pass through these sites. The contaminated land is not just the surface of the soil but also the underground and underground water. This contamination has the potential to damage the human factor and the environment. For qualitative quantification of the activity carried out in the Brad mining perimeter, we carried out an assessment of the impact of pollutant emissions...

The paper deals with the implementation of modern techniques and methods of surveillance in closed mining sites, for monitoring, assessing the real state and forecasting possible changes to provide an integrated picture of the state of the natural environment. The proposed system is designed as a tool with practical applicability in the decision making process of ecological restoration strategies of closed mining sites. Closed / abandoned mines have an acute need to deploy a sensor network due to their lack of wor...

Mining generates a negative impact on the areas after stopping mining activities. Causing mines closed because of their specific, multiple and varied adverse effects on the environment by land degradation, by vertical and horizontal surface and sliding heaps and tailings ponds; polluted surface waters and groundwater; hydrodynamic imbalance of groundwater; negative influences on the atmosphere, flora and fauna; chemical pollution of the soil. Mining gold mine Barza - Brad is currently stopped, the mine was closed....

The paper aims to solve pollution problems mining sites closed on the environmental components. In this regard it is proposed the use of microcontrollers and wireless sensors for warning exceeded limit values of environmental quality indicators. It wants to create a network of wireless sensors to anticipate the amount of pollutants to take measures to reduce pollution in the mining Brad chosen as a case study.

Sludge from sewage formats municipal byproducts are considered "undesirable" that focuses remove pollutants from wastewater and can be a danger to the environment.Lupeni dump was born by storing the waste material resulting from the preparation of coal.The material deposited on the two branches of the heap consists of sandstone rocks clay, marl, carbonaceous shales and sandstones.From the analysis it is observed that: the reaction is slightly alkaline soil (pH = 7.4); humus content: medium to good; containing coar...

In most industrialized countries the problem of air pollution has become a major concern with significant social and political implications, is considered a barrier to economic and social development, drawing attention to these natural resources, materials and energy are not inexhaustible. In the literature are numerous researches on environmental pollution, correlated or not with the consequences on animals and food of animal origin, and not least on health human. In recent times the environmental pollution has d...
