Environmental pollution with microplastics is a global concern, accompanied by a large body of research primarily focused on aquatic environments. Microplastic contamination has a considerable impact on both the biological diversity of aquatic ecosystems and human health. In this context, the present paper provides an overview of technologies and measures aimed at reducing the presence of microplastics in surface waters, emphasizing two complementary approaches: the removal of microplastics from transfer pathways ...

The assessment of the influence of economic activities on the population in the eastern region of the Jiu Valley (located in the south-western part of Romania) entails several stages. These include measuring the extent of air pollution, selecting a tool for evaluating air quality, and most importantly, implementing a method for estimating the environmental impact. The objective of the study is to analyze the environmental conditions by analyzing the data collected from the six designated locations and utilizing th...

Since ancient times, chromium oxide was used 2000 years ago by the Chinese to cover the tips of weapons and later, as late as 1988, hexavalent chromium was discovered to be dangerous to humans. Currently, many companies carry out chrome plating of plastic parts, which consists in creating a superficial layer of diffusion, of an iron-chromium alloy with up to 10 - 20% chromium. Coating by electrolytic deposition is the most widely used method for creating protective layers for plastic materials and consists in elec...

One of the areas in Romania where the environment felt from human activities is Jiu Valley (Petrosani Depression), an area where the main activity was mining. This fact led to pollution of the area, pollution that affects both health of population and tourism, which is considered as a viable economic alternative. Investigation of environmental components, identification and analysis of impact sources on air and surface waters are the objective of this paper, which is a first step of a larger research, that will le...

Soil and groundwater resources are natural resources of high ecological value, their protection against chemical degradation and pollution being of major interest and requesting a new methodology based on risk instruments. The need to implement methods for qualitative and quantitative assessment of ecotoxicological risk resides in objective assessment of effects pollutants have on ecosystems, to limit the transfer of xenobiotics to lower and upper levels of the food chain. In this sense, the team of the Environmen...

Urban noise is affecting an increasing number of people and this is why it is becoming a major environmental issue, being a known fact that it affects all human activities and constitutes a stress factor with negative effects on health. It can affect the population both physiologically and psychologically, having an influence on the elementary activities such as sleep, rest, study and communication. Noise in the environment - a harmful and unwanted sound from the outside - is spreading, both in duration and in geo...
