RESEARCH ON ENVIRONMENTAL FACTORS AFFECTED BY ECONOMIC ACTIVITIES IN EASTERN JIU VALLEY.

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 lead to establishing the pollution degree of the area under study. The paper presents pollution sources, methods of analyzing environmental indicators, as well as the impact of economic activities on the environment. The main conclusion of the scientific approach is that, in addition to mining activities that had and still have a negative impact on the environment, other economic activities carried out in the area, including household activities, also leave a negative impact on the environment. Which of these (quantitatively speaking) leave a larger or smaller footprint will be the subject of a future paper, that will quantify all air and water quality indicators. [ABSTRACT FROM AUTHOR]
