The technology and the installation of acid mine water treatment by bioaccumulation, is realized in three distinct stages, namely: the primary stage, consisting of raw water capture, treatment with neutralizing and coagulating chemical reagents, solid phase settling and sludge treatment, [I, II , IV, V], the secondary stage, consisting in the removal of heavy metals and the neutralization of acidity by passing the effluent of the first stage, through a battery of phytoextraction cells, [III],using for this purpose truncated cells. In the tertiary stage, the stabilization of heavy metals in the thickened clearing and the aerial part of the sedge takes place.

The paper aims to contribute to increasing the level of knowledge about climate change and its impact on cities in western Romania. The existing legislative framework at European and national level on resilience and adaptation to climate change is presented. The necessary climatic information is identified in order to create a scenario regarding the thermal stress and the health risk of the inhabitants of Timişoara. The results are extrapolated to other cities in the west of the country. The data obtained from the use of climate models are processed in order to use them to establish the necessary adaptation measures in order to reduce the risk to the health of the population due to future thermal stress. The paper presents uncertainties and limitations, as well as conclusions and personal contributions.

Pollution caused by closed mining activities is particularly difficult to treat because it dates back a very long time. Water contamination results from large-scale disturbance of the land on which the underground exploitation of the useful mineral substance took place. Discharges from underground mines can be treated as diffuse point sources; water quality is due to reactions that occur in an area that can cover tens of square kilometres. The main sources are groundwater, which increases after the pumping is stopped, and tailings stored in dumps and tailings ponds. When the mine closes, the pumps are stopped and the groundwater level rises until it reaches the surface or discharges into the aquifers above. Although discharges from wells and galleries are often the most visible sources, surface activities such as mineral processing, tailings and waste disposal are also a significant source of pollution. The river is located on the Barza gold-silver ore mining operation took place. The runoff waters present in this perimeter can transport contaminated sediments, where the tailings dumps are washed away by precipitation. The paper aims to identify the sources of surface water pollution in the Barza closed mining site that influences the quality of surface water.

Energy poverty has become a global problem, a phenomenon that has grown alarmingly due to the crisis caused by the COVID19 pandemic, the crisis of high energy prices in 2021, followed by the invasion of Ukraine by Russia in 2022. These recent events, as well as those associated with the energy transition that occurred in the last decades, have highlighted, in addition to the involvement of government institutions in terms of the necessity of policies in the field of energy, the need to research the phenomenon of energy poverty as well as the need for awareness of the phenomenon among local authorities and of the citizens.

Lately, more and more Non-governmental Organizations are rising up against the mining industry, but without offering a solution that is at least as viable in the safety and health of the population, which depends on ensuring Romania's energy security. It is recommended to capitalize on an efficient system of supply of solid fuel (lignite), production, transport, distribution and supply, which ensures the continuous supply of all consumers in conditions of accessibility, availability and affordability of prices, taking into account the evolution of environmental quality. surrounding. Research on coal mining at the Roia Quarry includes specific requirements in order to ensure a high degree of environmental protection during the project, including the organization of the site extension, as well as during the subsequent development of the activity.

Greenhouse gases (GESs) are gaseous constituents of the atmosphere, both natural and anthropogenic, which absorb and emit infrared radiation, being responsible for climate change. Currently, carbon has become the focus of scientists, politicians and the media, due to anthropogenic activities that generate large amounts of carbon, which has a significant impact on the global climate. In the Roia de Jiu quarry, greenhouse gases are emitted by the fuel consumption of the mining equipment, as well as by the trucks for transporting the materials. Research on climate change due to the Roia de Jiu quarry expansion activity includes calculations on greenhouse gas emissions from quarry equipment in 2019 and the capacity to store CO2 vegetation by type of land use.

Jiu Valley is in an extensive transition process from an area rich in coal deposits to an area with 0 Carbon emissions. Coal mining was carried out in 14 mining perimeters arranged along the Jiu Valley. At the same time, the extraction of the useful mineral substance resulted in waste material that was stored in tailings dumps. Out of the total of 49 landfills, 25 have been greened, 15 are inactive and 9 are active. The total area occupied by them is approximately 210 ha, arranged near mining operations, in the valleys of some streams and even in the vicinity of human settlements. The paper aims to identify the potential for soil contamination due to inactive tailings dumps. [ABSTRACT FROM AUTHOR]

Coal mining is a vital industrial activity but often associated with negative environmental effects, including the accumulation of waste containing heavy metals in tailings dump. These heavy metals, such as lead, chromium, copper, zinc, cadmium, mercury, and others, pose significant risks to the environment and human health. The mobility of these heavy metals is a major concern, as they can be released into soil and water during rain or erosion processes, contaminating water sources and affecting aquatic and terrestrial life. These metals can be taken over by plants and eventually end up in the trophic chain, including in humans. The toxicity of heavy metals is well known, with these substances having harmful effects on human health. In this paper, the main ways of transferring heavy metals into environmental components and their spatial distribution from sterile holes to water and soil environment components. As a case study, the sterile Balomir hole, an inactive hole for about 9 years resulting from the exploitation of the hule from the Uricani mine located in the Jiu Valley. [ABSTRACT FROM AUTHOR]

The research, concerning the development of underground facilities worldwide, it indicates that both a favourable environment for the use of the underground space (or space location understood as great) and a boost to the adoption of the method are required to achieve the underground construction of major underground facilities. A major incentive for the use of underground space is growing international concern on the environment, which led to rethinking future urban construction and industrial. It is clear that increased pressure on the use of terrestrial lead to two trends already present in many countries, or the construction of high-rise buildings or use scale growing facilities of underground space, variant seems however, it is the most advantageous. In this context it is important to plan new type of underground facilities wisely. Planning must be effectively controlled and used to maintain the natural surface and side effects involved in the development of underground projects are anticipated. [ABSTRACT FROM AUTHOR]

La gestion des sites, dont le sol a été pollué directement ou indirectement par des activités industrielles (exploitation minière), s'effectue dans le cadre de la loi sur l'environnement. Le sujet de cet article doit résoudre le problème de la sécurité et de la réhabilitation éventuelle de la lagune du «Triangle de Marienau». La gestion d'un site dans le contexte de sols pollués repose sur l'estimation du risque réel pour l'environnement, en particulier la santé humaine et la qualité de l'eau des aquifères, en fonction de l'utilisation prévue du site. La connaissance des mécanismes de mobilisation et de transfert joue un rôle tout aussi important à cet égard que l'identification de la présence d'un contaminant à un endroit donné.
