The research investigates the impact of persistent organic pollutants, particularly pesticides, on the aquatic ecosystems of the Jiul de Est basin. Pesticides are introduced into water bodies via surface runoff, infiltration, and atmospheric deposition, and their bioavailability is influenced by factors such as pH, temperature, and dissolved organic matter. The research evaluates the ecotoxicological effects on key aquatic species, including Salmo trutta fario (river trout) and Squalius cephalus (common chub), by ...

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...

Appropriate protection of the environment, as well as of the most vulnerable environmental factor, water, is impossible without the achievement of a civilization's progress in all its aspects (economic, social, etc.). Also, the lack of adequate economic support may lead to the impossibility of carrying out actions to protect and conserve water resources. Activities from eastern part of the Jiu Valley, constituted as integrated parts of economic growth and development, invariably degrade, through the specificity of...
