"The present study was conducted in the proximity of a chemical plant from Târgu-Mureș (Romania), where nitrogen-based fertilizers were produced. The quality of the environmental components was assessed in terms of general physico-chemical parameters and the content of nitrogen dissolved ions (NO3-, NO2-). The nitrate content in soil varied depending on the distance from the source and land use at sampling point. The nitrite content was correlated with possible transformations from the nitrate forms. For water, special attention should be paid to the nitrate content from the industrial effluent, which in one sample proved to be higher than the national legislation. Keywords: nitrogen-based fertilizers, surface water pollution, soil pollution"

"The importance of forests in our society is extremely significant, with multiple benefits for both the environment and people. Considering the high importance of forests and the need for responsible and sustainable utilization, various approaches have been developed to promote sustainable forestry in different ways. This paper focuses on identifying, classifying, and analysing these approaches in Romania and at the European level. Firstly, the legislative system, through its crucial role in establishing rules for different sectors, plays an important role in ensuring sustainable forestry. The entirety of laws that impact forests form the regulated tool of the state. On the other hand, organizations that benefit from goods and services provided by forests aim to assure customers that their activities do not have a negative impact on forests. Taking these factors into account, non-governmental organizations have developed different standards and policies to maintain and improve forest practices. These systems are not regulated by the state; rather, they are voluntary instruments. Their use depends on the willingness and interest of the forest owner or manager. Both types of instruments aim to improve forest practices and promote a sustainable approach to the utilization of forest resources. Keywords: Responsible forest management, voluntary system, reglemented system."

"The article aims to define, interpret, and identify the aims of Disaster Science, and to delimit the individual components along the examination of its disciplinary nature. Definition of the concept of Disaster Science, delimitation of its individual components from its concept, and further terminological examination of related elements. On the one hand, this is conducted with the help of the Internet and the so-called keyword search method in the Google search engine, specifically by searching for definitions, then by collecting the individual publications and the relevant bodies and organisations and analysing their use of terminology. The frequency of occurrence of disasters around the world is constantly increasing, their destructive effects can increasingly be felt. Their averting and elimination generally exceed the national level of protection, so the research results should be given priority. Among the conclusions of this publication stands the research priorities of Disaster Research having different disciplines, and due to its multi-, inter- and transdisciplinary nature, there is no unified consensus regarding the methodology and terms. The availability of literature of sociological origin is ensured, however, few works have been produced in Hungary on this topic, for instance, and even in the field of analysis of the effects of natural disasters. The Author analyses the elements of Disaster Science in an interdisciplinary manner, combining several disciplines, provides insight into Disaster Science and its research areas, and in terms of literary resources, the reader can get to know many, primarily international literature. Keywords: Disaster science, disaster risk management, discipline, disaster, hazard, risk."

"Most persistent organic pollutants (POPs) were made for specific purposes due to certain characteristic and properties. They can cause various diseases and are problematic for the environment due to their high persistence and toxicity. This study attests the presence of three classes of POPs namely polycyclic aromatic hydrocarbons (PAHs), organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in the upper urban soils of Cluj-Napoca, Romania. Soil samples were collected from 10 sampling points areas with heavy traffic. For determination of the compounds, gas chromatography coupled with mass spectrometry and with electron capture detector was used. The obtained results indicate a low level of pollution, the concentrations ranging between 8.83–184.92 ng/g for PAHs, 5.36–112.35 ng/g for PCBs, and 25.96–334.83 ng/g for OCPs. To identify the pollution emission sources, different PAHs and OCPs diagnostic ratios have been applied. Keywords: persistent organic pollutants, polycyclic aromatic hydrocarbons, polychlorinated biphenyls, organochlorine pesticides, upper urban soil"

"In the present study, in was investigated the groundwater quality from several private wells located in Seini city, Maramureș County (northwestern part of Romania). The investigated quality parameters were pH, redox potential, electrical conductivity, total dissolved solids, salinity, dissolved ions and heavy metals. The analysis showed that some of the investigated wells had a high content of nitrate, ammonium, and heavy metals. The continuous consumption of water from these sources can be a real threat for consumers’ health. The inhabitants should limit as much as possible the usage of water from these wells for drinking purposes and they should use the water from the local distribution network. Keywords: ground water quality, drinking water, chemical quality parameters"
