In addition, we have studied the heavy metal contamination of the surface waters from the vicinity of these disposal facilities. The heavy metals influence was investigated by analyzing various water and soil samples collected from two county areas where more rural disposal facilities were functioned. ZeEnit 700 atomic absorption spectrometer was used for the analysis of metals and the collected soil samples were mineralized according to ISO 11466, by extraction with aqua regia (3 parts HCl: 1 part HNO3). The evaluation of the soil analysis results from the area No. 1 proves that there is no potential impact, because the studied metals concentrations are below the alert threshold. Water analysis results from area No. 1, shows a quality class V for lead and nickel, whi...

The consequences and the exposure of living organisms to plastic pollution are not yet fully understand. The risks to health, environment and climate, due to the ubiquity and persistence of plastic are of great interest. The current study analyzes the perception of the Romanians regarding plastic pollution, in order to determine any pro-recycling behaviour of the local people and to recommend specific actions to reduce plastic pollution and the environmental risks associated with the studied region. The population is an important agent in waste management, in addition to local and central authorities, sanitation and recycling companies and/or public institutions. In order to achieve our goals, we developed a questionnaire that includes a series of questions related to people-s behaviour, knowledge, perceptions and feelings about waste management in relation to the environment, reducing single-use plastic and plastic hazards. The results demonstrated that 95.6% of the interviewees agreed that the use of plastic bags is harmful to the environment, 87.9% consider that plastic packaging of some products is sometimes unnecessary, 88.5% believe that recycling is the solution for removing plastic from the environment, and only 59.3% believe that the sanitation company is able to collect the waste selectively. The average of the answers related to the use of recyclable packaging shows that people are more and more concerned about the packaging of the purchased products, their recyclability, and the risks posed by plastic in the environment. Based on the people-s responses and willingness to get involved in reducing environmental plastic pollution, some measures adapted to the region have been recommended as useful for increasing the plastic recycling rate and reducing risks to the environment.

At Cluj-Napoca, the landfill of waste is the predominant strategy used for the municipal solid waste (MSW) management. Considering the environmental impact, landfill is one of the least desirable option, because in terms of limited control possibilities of emissions, it is an "end-of-pipe" treatment option. Other options as, recovery, recycling or waste treatment or other methods for waste management can also produce environmental impact, but as different as simple storage, they present some positive aspects, such as: reducing natural resources consumption, reducing emissions of greenhouse gases (GHG), reducing all of emission directly related to the environmental impact, and better land use planning possibilities. To do an accurate analysis of the environmental impacts resulted by the different management strategies of municipal solid waste, the life cycle as...

This paper aims to investigate the links between e-waste and ELVs streams and the circular economy approach of the EU. Romania is examined as a relevant case study for the central and eastern European Region regarding: (i) the current e-waste and ELVs management deficiencies and challenges in line with circular economy principles promoted by EU; (ii) analysis of E-waste and ELVs flows data; and (iii) best circular economy initiatives related to e-waste and ELVs in Romania, including the opportunity to create new jobs in treatment activities that the simple operations from the first stages of e-waste recycling can produce locally and regionally in Romania.

România se confruntă cu probleme critice de mediu, inegalități socio-economice severe, disparități urban-rurale și regionale mai ales la periferia UE. Tranziția României către o economie circulară este un obiectiv prioritar asumat prin intermediul politicelor de mediu ale UE. Această lucrare analizează pe de o parte, deficiențile sistemelor actuale bazate pe economia liniară (deșeuri solide, ape uzate, energie, resurse naturale, inechități socio-economice, consum iresponsabil) precum și modele de bune practici în diferite sectoare economice care pot stimula progresul României către o economie circulară și o societate mai rezilientă.

The hazardous waste landfills positioning directly on the soil without other protection it is known as being a source of pollution for the underground, and the wastes resulted from ore processing are included in the hazardous waste category, due to their hazardous substances content and their large quantities. This study presents the soil pollution in the near vicinity of the tailing dams: Aurul, Bozânta Nou and Bozânta Vechi. Soil samples located in the proximity of the tailing dams as well as samples from inside the tailing dams were analysed in order to determine the acid water drainage. For the soil samples were determined the concentrations for As, Cd, Cu, Pb, Mn, Zn, total cyanide and the pH values. The results were compared with the maximum admissible threshold values in the Romanian environmental protection regulations, for less sensitive soils. Exc...

The objective of the study is to find out what are drivers, barriers and practices in the vision of young people and adolescents in Romania, in terms of social entrepreneurship. The study took place online and aimed to facilitate access to quality information related to the integration of the sustainable development principles in daily behaviors of young people, their willingness to become involved in social entrepreneurship activities. As a working methodology, a questionnaire is applied to adolescents and young people, before and after the seminars they participate, in which they are asked about how they see their involvement in some activities of the environmental protection and in social entrepreneurship activities or in what way they want to contribute ...

Metal sulphide minerals from the mining waste facilities have a potential to produce acid rock drainage (ARD) and to generate risk for the environment, including for the water resources. Some of the mining waste deposits from the region are located near the town of Baia Mare, close to the residential areas, the agricultural lands and the surface water. The short migration path between the sources and the sensitive receptors is causing an increased environmental risk. The main contaminants found in the area are heavy metals and metalloids, such as: Pb, Zn, Cd, Cu, Ni and As. Their concentrations measured in the water samples from the area exceeded the pollution thresholds. Moreover, there were measured high concentrations of heavy metals in the groundwater from the wells in the villages located downstream of the mining waste facilities. This water is us...
